Figure 86. Pressing out the ball joint pin of the steering rod from the steering column pivot arm
Disconnect the suspension arm 1 from the body bracket 4 and remove the arm assembly with the tensioner 8 and bracket 10. Unscrew the bolts 11 securing the shoe guide to the steering knuckle 12, hang the caliper assembly with the shoes on a technological hook to the body so that the hose is not loaded.
By moving the stand 6 to the side and turning it, the splined tail of the constant velocity joint is removed from the wheel hub. From the engine compartment side, the protective cap of the support is removed, nuts 1 (see figure 82) fastening the telescopic strut to the body and remove the front suspension strut assembly with the steering knuckle and wheel hub.
While performing the above operations, remove the other front suspension strut. Then remove struts 5 (see figure 85), unscrew the nuts securing the anti-roll bar to the body and carefully remove the anti-roll bar from under the exhaust pipe.
Installation of front suspension components and parts is carried out in the reverse order of removal, taking into account the following:
- the front strut nuts, the nuts of the suspension arm mounting bolts to the body brackets, the nuts of the stabilizer struts mounting to the suspension arms and the nuts of the stabilizer bar mounting to the body are pre-tightened until the clearances in the joints are selected;
- all nuts securing rubber-metal hinges, rubber bushings and cushions are finally tightened to the torques specified in Appendix 1, under a static load of 320 kg, which corresponds to the mass of 4 people and 40 kg of cargo in the trunk;
- when installing bracket 10 (see figure 85) when fastening the strut to the body, care is taken not to damage the threads in the welded bushings of the body;
- when installing the anti-roll bar, do not allow longitudinal displacement of the pads on the bar, as they must be located at the same distance from the center of the bar (the distance between the centers of the pillow brackets should be 700 mm). First, tighten the front mounting bolts of the 3 stabilizer cushion brackets (from the side of the cut of the pillows), and then the rear ones. At the same time, make sure that when tightening the bolts, the gap in the cushion cuts is completely eliminated and the cushions are not damaged.
On cars manufactured in 1985, UG-9 anaerobic glue was used in the splined connection of the wheel hub with the outer joint housing. In case of reuse of the wheel hub and joint housing, the glue is removed and immediately before assembly, the splines of the hub and joint are degreased and UG-9 anaerobic glue is applied to the splined part of the joint housing farthest from the threaded end in a 10-20 mm annular strip. After this, the wheel hub is put on and the hub fastening nut is tightened to a torque of 23-25 kgf·m. During the first 4 hours required for the polymerization of the glue, the car is transported by towing or under its own power, provided that it starts off smoothly, without jerks, at a speed of no more than 10 km/h.
