Regular king pins are able to serve properly for a long time only if the driver complies with all technological requirements for adjusting and assembling the elements in question, especially after the plant begins to install carbon fiber liners. In the friction zone, carbon fiber is able to work properly without lubrication until dirt appears and the tightness of the seal is not violated. After that, the liners quickly fail. Nevertheless, no matter how many positive qualities carbon fiber kingpins have, it is only clear that this part of the UAZ is considered a weak point. Sooner or later, you will need to replace the pivots with a UAZ.

The features of this procedure are of interest to many car owners, along with the feasibility of switching the manufacturer to liners instead of bushings. The main point is that the pivot assembly produced at the factory requires too much attention to itself. As mentioned earlier, a high performance indicator is observed only when the owner of the car complies with all technological requirements when assembling and adjusting the pivots on the UAZ.

If the necessary requirements are not observed when tightening the pivots during operation, the cone or slotted nut may shrink, resulting in play, often in the upper sample. The transfer of the load distributed along the perimeter of the liner to a point is also carried out. As a result, the carbon fiber is damaged. In any case, the hauling immediately leads to the fact that you will lose control of the cars. IN this case it will be relevant to replace the pivots with a UAZ.

If you do not know how to change the king pin for a UAZ, it is recommended that you familiarize yourself with the following technologies.

Installation of pivots depending on their type:

Installation of pins with a bronze insert. Bronze pins are theoretically strong even under heavy suspension shocks. They are more durable compared to bearings, which is why they are placed for heavy off-road. Kingpins with bronze liners give a good result on all UAZ vehicles. It is worth remembering that during the first two thousand kilometers, turning the steering wheel will be a little difficult. After the break-in, when the castor angle increases, the installation is correct, and the lubrication is of high quality, you will exert less effort on the UAZ relative steering wheel. When installing a king pin with bronze liners on the UAZ, if possible, it is recommended to increase the castor angle so that the wheels can more easily return to their original position on their own without much effort on the part of the driver. The use of bronze pivots on UAZ is considered the most inexpensive and at the same time reliable solution to the problem of low-quality pivots. In the event of any problems, it is imperative that the pivots on the UAZ be repaired in a timely manner.
Installation of pivots on bearings. UAZ control is greatly facilitated by the pivots on bearings, they are also quite reliable. If the constant operation of the UAZ on heavy off-road is not included in your plans, it would be most advisable to install a kingpin on bearings. The procedure in question will cost significantly more than installing similar elements with bronze liners. In this case, it is mandatory to install a steering damper. Without this element, the car will behave as if the front wheels need to be balanced.

If you do not know how to replace the kingpin with a UAZ, it is recommended to use the following step-by-step instructions.

Step-by-step technology for replacing pivots:

Drain the oil from the axle, jack up the axle and chock the wheels.
Unscrew the brake caliper together with the disc.
Unscrew the brake shield and remove the wire assembly together with the bearing housing.
Remove the steering tip and unscrew the lower oiler.
Remove the kingpin cap along with the lubrication valve.
Remove the plug from the lower king pin.
Soak the disassembled kingpins and disassemble the second side in the same sequence.
Thoroughly clean the removed units and inspect them visually.
Lubricate the bushings and compress them.
Clear the swarf from the lubrication spiral channel and inspect it.
Replace the axle shaft seals if necessary, then lubricate the lips with oil.
Check the pins in the trunnion upon completion of work. Each threaded connection must be checked on the CV joint. View the axial movement of the knuckle.
Install the oiler and king pin cover.
Lubricate the drive neck and insert the wire after the final check.
Assemble all knots in reverse order.

On this, the procedure for replacing the pivots hastily completed. It is highly recommended that you work with someone who understands the subject if you know absolutely nothing about changing pivots.

Video instruction - "Replacing the pivots on the UAZ"

The chassis of the Ulyanovsk off-road UAZ Patriot periodically needs maintenance. In order for all components in the suspension to function properly, timely periodic inspection for the presence of wear is required, after which the part that has become unusable must be replaced. Sometimes only a tightening of the pivots is required. In this article we will consider the question of how to tighten the king pin.

To pull and adjust the pivot elements should be inclined in the following three cases:

when wear is observed on the bearings of the swivel, which is confirmed by the appearance of play;
during repair operations related to the disassembly and maintenance of the pivot pin;
if the pivot joint needs to be replaced.

In the first variant, the rotary mechanism is not completely disassembled. Here you can do only with an additional tightening of the nuts of the adjustment mechanism.

In other situations, the front axle is subject to disassembly, which involves the complete removal of the axle shafts with related drive parts.

Instruments

Before the repair procedure, the UAZ Patriot car should be thoroughly washed.

We use the following set of tools and devices:

two jacks;
a wrench that allows you to tighten the previously specified nuts;
hammer;
set of pads.

Special equipment can be found in kits that are sold for repair work on replacing liners and kingpins. If it is not available, you will need to purchase separately.

The wrench looks like a splined pad, the protrusions of which are aligned with special grooves on the clamping nut. To ensure the most accurate tightening, you will need to use a torque wrench.

King pin adjustment

When minor gaps appear, the adjustment process can be performed without resorting to disassembling the steering knuckle.

The pivots can be adjusted independently.

We place the SUV on a flat area, hang the front end with the help of jacks and dismantle the wheels.
We remove the protective linings and gaskets present at the clamping bushings of the pivots.
A few hammer blows on the pivot pin help to settle it, thereby reducing the preload.
Using a special key, we tighten the clamping sleeve until the backlash that was previously present is eliminated. We perform broach at 10-12º, with a moment of approximately 30 Nm, but no more.
We carry out the adjustment procedure in turn: first on the upper support, and then on the lower one.
We check the amount of effort when moving the fist. Recall that it must be free.
Lubricate the clamping bushings, after which we install the gasket and protective cover.

If there is significant play in the suspension, then the usual kingpin adjustment will not be effective. Here you will need to replace the liners present at the ball joint. This action involves the complete disassembly of the fist. Also, during assembly, it will be necessary to adjust the pivot mechanism.

We act

We remove the caliper with the UAZ Patriot brake disc. We hang it to some suspension element in order to avoid the impact of the load on the brake circuit hose.
We release the fasteners of the trunnion and dismantle the assembly complete with the hub, clutch and protective cover of the brake mechanism.
We remove the half shaft. For this purpose, with the help of rotational-translational efforts, we pull the axis itself towards ourselves. It should disengage from the front axle.
We unscrew the tie rod ends from the pin. We turn out the bolts and dismantle the steering knuckle.
We fix the assembly in a vice and disassemble it in order to replace worn components (liners).
According to the reverse algorithm of actions, we collect a fist.
When installing, do not forget about the lubrication of the nodes.
Upon completion of the replacement procedure in the UAZ Patriot car, you will need to resort to adjusting the toe-in of the front wheels. This will prevent subsequent uneven abrasion of tires.

Important! After disassembly, it will be necessary to correctly adjust the relative position of the knuckle body with the pivot mechanism. Here you need to achieve the exact location of the ball bearings in relation to the fist. The permissible error should not exceed 0.2 mm. General moment tightening must not exceed 250 Nm.

After the whole complex of works, the UAZ Patriot has improved handling. Now you know how to tighten the kingpin.

Summing up

The repair procedure considered by us and tightening of the pivots is available for independent execution without contacting the service. Here it is recommended to involve a partner, since the nodes in the suspension of the UAZ Patriot are heavy and another pair of hands is needed for the correct assembly and adjustment process.

UAZ "Hunter" is a fairly practical SUV that feels great on various types of roads. This car is distinguished by a rather strict look in modern assembly and processing.

General characteristics of the UAZ "Hunter"

"Hunter" in all its glory

Outwardly, this car is very similar to a military jeep, but at the same time, the manufacturer took care of the convenience and comfort of the driver and his passengers. "Hunter" is of two types.

With petrol engine.
With diesel engine.

The car is very roomy and quite comfortable, has a large carrying capacity. To increase comfort, the manufacturer equipped the seats with an adjustment mechanism, so any person will be comfortable in the car. The driver will get a lot of pleasure from traveling on the UAZ "Hunter" in any terrain.

One of the most discussed and controversial topics is the repair and adjustment of the pivot assembly of this vehicle.

The choice of modification of the pivot assembly

The pivots of the steering knuckle of the UAZ "Hunter" car are:

on bushings;

bearings;

balls.

What to choose from this, the car owner decides. Opinions on this issue vary greatly. It is easier for someone to change the liner more often, and someone installs the bearing and for a long time forgets about repairing and adjusting the pivots on the UAZ Hunter. Of course, the most budgetary repair is the replacement of the sleeve. But whichever option is chosen, the king pins must always be given great attention, change them in time and adjust as needed.

Assembly of the pivot assembly

The installation of pivots with angular contact tapered bearings on the front axle of the UAZ Hunter instead of standard plastic parts provides many advantages. Often they change the material of the kingpin, but the result is worse than when replacing the kingpin itself, since the problem lies in the composition of the assembly. Having understood the operation of the pivots, you can easily understand that the support is needed stable, otherwise the object to be installed may be deformed.

It cannot be said that such a design is unsuitable for use, but replacing the pivots with a UAZ, installing bearings and adjusting will help to avoid some problems in the future.

When choosing the first option for pivots on a UAZ, the car will require timely maintenance and repair. But modern car owners do not want to repair the same part several times. That is why the so-called disposable spare parts are gaining immense popularity. But when buying a UAZ car, it is worth remembering that its internal design is quite old. It requires constant adjustment, repair and tuning. However, imported cars of the same class are in many ways inferior to this car due to the fact that the UAZ can be adjusted to suit itself, and you will have to spend quite a bit on it.

The correct replacement of pivots for UAZ allows the car owner to forget about adjustment, repair, purchase of spare parts and so on for a long time. How does the quality of UAZ pivots affect the operation of the machine?

When choosing one or another node mechanism, you should pay attention to the following parameters.

The possibility of heat treatment.
The material from which the part is made and the quality of the bearing.
Landing and admission of pivots.
Part wear resistance.

The master installs the node on the machine

A well-made, properly installed and well-adjusted set of pivots UAZ "Hunter" will never lead to resonance. It is worth recalling that we are talking about mounting the assembly on the bearing.

Repair and adjustment of pivots

Cars such as UAZ should be repaired in specialized centers. There, experts can easily install and adjust both kingpin sets and any other necessary parts. But it also happens that the owner cannot or does not want to trust his car to other people, but wants to do everything himself. It is worth figuring out what the sequence of actions is when replacing, repairing and adjusting the pivot assembly.

First you need to hang out the bridge, then remove the wheel, then unscrew the kingpin nut, unscrew the clamping sleeve with a wrench specially designed for this, and then remove the insert and kingpin. This is a laborious and lengthy procedure. Without experience in such matters, you can be transported for quite a long time. You will have to change the liners for king pins quite often.

The constant assembly and disassembly of large parts sooner or later leads to the fact that the owner of the UAZ nevertheless decides to replace not the liner, but to install the bearing. And not in vain. This will save you a lot of time, effort and money.

A step-by-step description of the repair, replacement and adjustment of the pivot assembly.

It is necessary to prepare keys for "19", "22" and "24", a device for installing and removing bushings, a dynamic key.
Put the car on the handbrake, put the stop on the rear wheels, raise the front of the car with a jack and remove the wheel.
Next, the steering knuckle is removed. To do this, you first need to dismantle the disk, then unscrew the bolts securing the fist, remove the trunnion with the hub, which are attached to six bolts, remove the axle shaft. After that, separate the tie rod end from the steering knuckle, unscrew the bolts securing the support to the axle shaft, remove the wheel stop stop and, as a result, dismantle the steering knuckle.
Unscrew the nut with a suitable wrench, remove the gasket and trim.
Turn out the clamping sleeve with a special tool.
Remove the kingpin. In the same sequence, remove the second kingpin from the other side.
Next, you need to remove the ball joint. Use a screwdriver or other handy tool to pry up on the earbud and pull it out.
Install the ball joint in the steering knuckle, lubricate and install the king pins.
Tighten bushings evenly. Do not forget about filling the cavity above the bushing with special grease.

Further, the actions are carried out in the reverse order: linings with gaskets are installed, a steering knuckle is placed and adjustment is carried out. At the end of the repair, it is imperative to adjust the front hubs.

Node device

The kingpin is necessary to move the wheel of the machine within the limits set in the steering mechanism. The main component of the king pin is a spherical hinge.

The usual design is famous for its problems: every day it is necessary to check the play connecting the steering knuckle to the ball joint, control the presence of lubrication, notice problems with gaskets in time and eliminate them.

There are several types of pivots:

with bronze insert;
on bearings.

Consider a kingpin with a bronze insert. This option is very durable, it will not be damaged even if the suspension is hit hard. These parts have shown themselves well on all types of roads. A kingpin with a bronze insert is put on UAZ 469 or UAZ "loaf" cars, achieving excellent driving characteristics of the car. When the car has been run-in at 2 thousand kilometers, it will become easier to drive. To install the part with a bronze insert, it is necessary to increase the angle of the castor for free rotation of the wheels.

It becomes much easier to drive the UAZ thanks to the pivots on bearings, they are very practical to use. Especially if the motorist does not intend to drive the UAZ on difficult roads. Installing a kingpin on bearings is expensive, putting bronze liners will be much cheaper. Before mounting the part, it is necessary to install a steering damper or balance the front wheels.

Repair and replacement of the pivot assembly

UAZ king pin lubrication

Repair of cars such as UAZ is best done in car dealerships. Experienced professionals without any problems will set up all the components of the king pin, troubleshoot other parts. But some motorists can perfectly fix the car without outside help.

Repair or replacement of pivots on the UAZ Patriot takes place in several stages:

prepare the tool needed to remove the bushing;
put the car on the handbrake, it is recommended to support the car from behind and raise it with a jack, remove the wheel from the front;
dismantle the fist from the turn;
unscrew the washer with the appropriate key, remove the interfering parts;
remove the clamp bushings;
remove the pins;
remove the supports from the balls using the right tool;
return everything to its place;
apply a special gel.

By following these steps, you can make repairs yourself. Ordinary UAZ 469 pivots are able to work without breaking for a very long time, if the motorist complies with the necessary operating requirements, recommendations for self-disassembly of the necessary elements and repair.

The manufacturer installs on UAZ and carbon-fiber kingpins. They have positive reviews, but are still a weak link in the car. Some time will pass, and they will have to be changed.

Replacement is carried out in the following sequence:

drain the oil, hang the bridge, put a stupor under the wheels;
unscrew the caliper responsible for the brake;
remove the brake shield;
remove the steering wheel;
remove the pins and valves of the gels from above and below;
wash the kingpin, which has just been removed;
wash all removed nodes, inspect them;
lubricate bushings, compress;
remove chips from the spiral channel;
change the semi-axial oil seals, if necessary;
make sure that the king pin is working;
return the oilers and pivot covers to their places;
install cords;
put everything back after repair.

Required tool:

Cuff 32x50-10 with spring assembly, 2 pcs.; Inserts (plastic or bronze), 4 pcs.; Ball bearing gasket (Cat. No. 31-0121238), 2 pcs.; SHRUS-4M; Cold welding;

We install a new cuff of the axle shaft in the ball joint. The orientation of the cuff is carried out along the sealing spring - it must be on the side of the final drive gearbox (i.e., when installing, the spring should "look" at you). Install the gasket on the end of the ball joint.

In cases where there is slight wear or deformation of the kingpin support along the inner hemisphere, it is allowed to use composite materials to fill the damaged areas. In this case, it is necessary to install the pivots and bushings without waiting for the polymerization of the composition.

We install new liners (plastic or bronze) in the pivot bearings on the ball joint and apply SHRUS-4M grease to the inner surface of the liners.

Step 14 Assemble the steering knuckle

Required tool:

Litol-24, 0.5 kg per side; SHRUS-4M, 50-75 grams;

We install new thrust washers of the steering knuckle joint in the ball joint and the steering knuckle housing.

Before assembly, apply Litol-24 grease, about 0.5 kg, to the inner surfaces of the steering knuckle housing and ball joint

and insert the axle shaft with a constant velocity joint, on which SHRUS-4M is applied up to 100 grams.

Step 15 Installing the ball joint

We put a ball joint on the axle shaft, while monitoring the correct orientation of it.
The bottom of the ball joint is determined very simply: on the bottom side of the flange there are three holes, on the top side there are two. We recommend that you notice the orientation of the steering knuckle housings during disassembly, for example, by punching or paint.
We pay attention to this, since the knot is assembled in any combination and you can easily make a mistake.

Step 16 Lubricate the pivots

Required tool:

Kingpins; SHRUS-4M up to 30 grams";

Lubricate the conical surface and thread of the clamping sleeve, the rubbing surfaces of the king pin with SHRUS-4M grease

Step 17: Tightening the clamping sleeves

Required tool:

Pivot key; Head for 27; Torque wrench up to 30 kgf*m; Soft (copper or aluminum) mandrel; Hammer; Calipers;

We insert the pins into the threaded holes of the steering knuckle housing and wrap the clamping sleeves until the pins stop in the supports. If you have installed kingpins with a channel for lubrication, then for further work it is necessary to unscrew the grease fittings from them with an "8" wrench

We center the body of the steering knuckle relative to the ball joint with an accuracy of 0.2 mm from the ends of the influxes of the body of the steering knuckle, using a kingpin wrench with a "27" head

1 - Pin;
2 - Body of the rotary knuckle;
3 - Expanding sleeve;
4 - Kingpin;
5 - Insert;
6 - Hinge of equal angular velocities;
7 - Ball bearing;
A and B - Controlled dimensions, A=B

Alternately increasing the torque by 2-3 kgf * m, using torque wrench (periodically monitoring the symmetry with respect to the ends, the deviation should not exceed 0.2 mm), tighten the clamping sleeves with a final torque of 20-25 kgf * m.
With a successive increase in the torque of the clamping sleeve, each time through soft mandrel strike with a hammer (video clip) along the axis of the pivots on both sides.
It is necessary to ensure the accuracy of the symmetry of the installation of the ball joint of 0.2 mm, relative to the ends of the influxes of the steering knuckle housing.
Measurements are made using caliper.
This centering is necessary for the correct operation of the axle shaft seals and to reduce the load on the constant velocity joints.

Please note that after tightening the clamping bushings with a force of 25 kgf * m, the ball joint rotates very tightly relative to the steering knuckle housing, as it should be. The turning force is adjusted separately - by tightening the pivot nuts ().

Step 18. Installing the cage and cuff of the steering knuckle

Required tool:

Litol-24, 100 grams; Head for 10

We stuff Litol-24 into the cavity between the ball joint and the steering knuckle housing.

Then install the cuff of the steering knuckle ..

We install a felt ring (ring SP134-12-5), which must first be soaked in machine oil.

Installing the steering knuckle collar

Using the "10" head, we screw it on eight M6x12 bolts

Step 19: Adjusting the Stop Bolt

Required tool:

Key for 12, 14, 17; Caliper with depth gauge (Columbic);

We screw in the locking bolt-stop with a lock nut, set the previously measured height on the caliper and fix it with a "17" key and a "12" key.

We fasten the bolt M10x1x16 with a "14" key.

Step 20: Installing the Gasket and Knuckle Arm

Required tool:

Head for 19; Gasket for the kingpin pad (Cat. No. 3160-2304028), 3 pcs.; Swing arm gasket (p/n 3160-2304029), 1 pc.

We install the gasket, lining and screw the M16x1.5 nut with the flange onto the kingpin.

We install the gasket and the steering knuckle lever, expander bushings and fasten them onto four Ml2x1.25 nuts using the “19” head and screw the M16x1.5 nut with a flange onto the kingpin. On the this photo a variant of the steering knuckle lever for UAZ-374195 vehicles and its modifications is presented

Step 21. Installing the steering knuckle with the axle shaft

Required tool:

Key for 14

We fasten the steering knuckle with the axle shaft to the flange of the axle shaft housing with five special bolts Ml0x1x30, two of them having previously put on the rotation limit, with the "14" key until it stops.

Attention, after a run of 200-500 kilometers, repeat the tightening of the indicated five special bolts Ml0x1x30
