Front suspension
The front suspension has an independent design. Steering knuckles are connected by upper and lower suspension arms (control levers) through ball bearings. Opposite ends of the levers are bolted to the frame. The standard equipment includes a stabilizer bar, which reduces the rocking and roll of the car when cornering.
Instead of coil springs, torsion bars are used, which are attached to the upper suspension arms.
The front suspension is based on telescopic shock absorbers. The lower shock absorber mounts are bolted to the lower suspension arms. The upper ends of the shock absorbers are fixed in the support brackets of the carrier frame.
Rear suspension
Rear Suspension Components
1 - Lower suspension arm; 2 - Upper suspension arm; 3 - Helical spring; 4 - Clamps for fastening the anti-roll bar; 5 - Bar stabilizer bar; 6 - Rear axle; 7 - Bushing of the upper suspension arm; 8 - shock absorber; 9 - Rack of a bar of the stabilizer of cross-section stability; 10 - Lower shock absorber support
The rear suspension is organized by a pair of coil springs, two telescopic shock absorbers, four levers (two lower and two upper) and a torque rod connecting the left end of the bridge with the beam of the supporting frame. The anti-roll bar is bolted to the rear axle assembly and is attached to the vehicle frame by means of two racks (refer to illustration above).
Steering gear
The models under consideration are equipped with a rack-and-pinion hydraulic power steering connected to the steering knuckles by means of two steering rods. The crankcase of the mechanism is attached to the transverse beam.
Often during the maintenance of suspension and steering components, one has to deal with hard-to-return fasteners. «sticking» fasteners due to the fact that they are constantly exposed to external influences, are in contact with water, dirt, soot and other substances that contribute to the development of corrosion. In order to facilitate the procedure for giving such «stuck» fasteners, it should be impregnated in advance with a copious amount of penetrating oil. Scouring exposed threaded parts of fasteners with a stiff wire brush also helps loosen rusted nuts. Sometimes, in especially severe cases, for letting go «stuck» bolts / nuts, you can use a drift. The punch rests against the edge of the slot of the nut / bolt head, then sharp blows are applied to its opposite end with a hammer. Make sure that the drift does not break, try not to damage the thread with inaccurate blows. Heating a non-retractable fastener and the surrounding surface of the component with a blowtorch or gas burner is also a fairly effective method, although the drafters of this Guide do not recommend resorting to this technology unless absolutely necessary due to its potential danger associated with the possibility of fire and the risk of burns. To increase the torque when releasing fasteners, various kinds of extensions, gates and pipe nozzles are used on them. However, remember that you should not use this kind of amplifying devices complete with equipped «ratchet» drive - the risk of failure of the ratchet mechanism is too great. Sometimes «ingrained» the fastener begins to give in after it is preliminarily slightly tightened clockwise. All fasteners, the release of which required the use of extraordinary measures during assembly, must be replaced!
Note. After giving the fastener, carefully check its condition and, if necessary, replace it with elements of the same size. When assembling, tighten the fasteners of the suspension and steering components strictly with the required force.
Attention! Never try to straighten deformed suspension and steering components - replace defective parts with new ones!
Since the maintenance procedures for the suspension components are performed under the vehicle, care should be taken in advance to raise the vehicle and fix it in a raised position (prepare a reliable jack and props).
Attention! Under no circumstances should you carry out any work under the vehicle, which has only been secured in the raised position with a jack!
