In detail: do-it-yourself repair of the front suspension of a UAZ patriot from a real master for the site my.housecope.com.

In the design of each car, an element such as a suspension plays an important role. It is thanks to the suspension that the driver and passengers during the trip do not experience all the negativity from movement on the roads. The more complex the suspension on the car, the more comfortable the passengers and the driver feel. The Ulyanovsk-made SUV UAZ 3163 Patriot has both rear and front suspensions. You can learn more about the rear suspension from this material. Today we will pay attention to the design features of the front suspension of the UAZ 3163, and also consider what this device represents.

On the UAZ Patriot SUV, the front suspension is dependent and is presented in the form of the following devices:

  • coil springs;
  • shock absorbers of hydraulic type;
  • anti-roll bars;
  • ball pins and longitudinal rods.

The longitudinal rods and the transverse link are designed to ensure that the optional front axle is properly secured. The rods are directly attached to the front axle structure by means of non-separable silent blocks and brackets. The second end of the rod is fixed to the frame of the UAZ 3163 SUV by means of rubber hinges.

Two telescopic shock absorbers, which also serve to limit the suspension travel, play the main role in removing the vibrations of the vehicle. The rear is also equipped with two shock absorbers, but they are different from the front ones, therefore they are not interchangeable.

The steering knuckles have hubs on which the brake discs are located. The rotation of the hub is provided by two roller bearings on each side, which eventually deteriorate and require replacement. Bearing adjustment is carried out using a nut located on a trunnion with a locknut.

The front suspension of the UAZ 3163 Patriot SUV is subject to various negative factors if it is used for its intended purpose. Therefore, you can often hear extraneous sounds from under a moving car. At the first sign of a front suspension malfunction, it is important to troubleshoot immediately and remedy them if possible.

Checking the suspension on the UAZ Patriot SUV is carried out by carrying out the following actions:

  • First, you should pay attention to the condition of the rubber-metal seals or hinges, which are the very first contenders for failure.
  • The suspension arms are also subject to inspection, on which various defects in the form of cracks, chips and other types of damage can often appear.
  • A visual inspection of the shock absorbers is also carried out, which may have such types of damage as malfunctioning bushings, as well as violation of the integrity of the device itself, drips.

The design of the front suspension of all vehicles is much more complex than the rear. This is primarily due to the fact that the front wheels are assigned the control function. Therefore, it is very important that the structure is always in good order and does not let you down on the way. To do this, periodic maintenance of the undercarriage should be carried out, even by placing the machine in an inspection pit and carrying out a visual inspection. If various types of malfunctions are identified, then only repair will help.

What is the repair of the front suspension of the UAZ 3163 SUV, we will consider further.

If on most passenger cars the front suspension structure is independent, then on the Patriot and many other SUVs it is dependent. To repair the suspension on the UAZ 3163 Patriot, the first step is to find out the cause of the malfunction. There can be many reasons, as you understand, but frequent breakdowns are already known to the owners of this car.

Before repairing the suspension, you should carry out dismantling work, which consists of the following steps:

  • the car is placed in the inspection pit;
  • wheels are dismantled, as well as tie rod ends;
  • the front wheel calipers are also removed;
  • the pivots are removed and they are repaired or the ball bearings are replaced;
  • the spring is dismantled by means of a special tool to compress it;
  • shock absorbers are dismantled, and they are repaired or replaced.

Depending on the malfunction, an appropriate repair of the unit or mechanism is carried out. Some devices need to be replaced and others can be repaired, for example, ball joints need to be replaced and shock absorbers are repaired. The springs sag over time, so in order not to replace them, special polyurethane spacers are installed.
