Rear suspension (figure 1.2.a) also consists of a MacPherson strut, four wishbones (two front and two rear) and two longitudinal levers. The upper end of the flock is attached to the car body. The lower end of the strut rests against the rear axle hub support. The outer ends of the wishbones are bolted to the lower parts of the hub supports. In the longitudinal direction, the hub supports are fixed using longitudinal levers. The anti-roll bar is attached to the body using two brackets and to the wishbones using earrings (figure 1.2,b).
The rack and pinion steering mechanism is located behind the engine, on the subframe. It is connected to the steering knuckles by means of steering rods. The inner ends of the rods are protected by rubber boots. It is necessary to periodically inspect these covers and check for any tears or grease leaks.
The power steering system consists of a hydraulic pump and a system of hoses and pipes. Periodically check the presence of oil in the booster pump reservoir (see chapter 1).
The steering wheel is mounted on a steering shaft, which is connected to the steering gear via a cardan joint. Increased play in the steering may be due to wear of the universal joint, rack and pinion, tie rod end joints, or loose steering component mounting bolts.
Often when performing repair work on the suspension or steering gear, you may encounter connections that cannot be loosened. The fact is that these connections are exposed to water, dirt, etc., which leads to the formation of rust. To make disassembling these connections easier, generously moisten them with liquid oil or a special liquid and let it soak in for some time, clean the nuts and bolts with a wire brush. As a last resort, you can try to loosen the connection by first tapping it with a hammer. It makes disassembling and heating the connection easier using a soldering iron, although in this case there is an obvious fire hazard. Sometimes, to loosen a nut, you first need to squeeze it. Any connections that are destroyed or damaged during assembly must be replaced with new ones.

Because the procedures described in this chapter require raising the vehicle. You will need a pair of sturdy supports for the car. A hydraulic trolley jack is preferable as it allows you to lift and support various components during disassembly and assembly.
Caution! Never, under any circumstances, crawl under a vehicle that is supported only by a jack. If you remove any suspension or steering fastener, inspect it carefully and, if necessary, replace it with new ones of the same type, size and quality. Tighten the connections to torque. given in Technical data. Never heat or straighten suspension or steering components. Replace all damaged and deformed parts with new ones.
