Removal of the transverse steering rod must be carried out in the following order.
Prepare the "32.3.160" device. Fix the relative position of the wheel relative to the hub with paint or a marker. Hang the front part of the car on stands and remove the front wheel. If necessary, remove the side panel of the engine crankcase protection.
Using the "32.3.090" tool or a standard "779-1" type puller, loosen the ball joint mounting nut on the swivel support (arrow, see Fig. 12.18) and disconnect the transverse steering rod. Cut off the clamps and remove the corrugated protective cover.
Insert the toothed rack into the steering mechanism as far as possible. Unscrew the transverse steering rod from the toothed rack using the device "32.3.160" (fig. 12.23).
On the old steering rod, determine the dimension "A" (see fig. 12.21) and set it on the new rod, which will make it easier to adjust the toe-in.
Install a new corrugated cover (4, see Fig. 12.22) and clamps (3 and 5). Install the transverse steering rod on the toothed rack (right and left) and tighten it to a torque of 110–120 N·m (11.0–12.0 kgf·m). Replace the self-locking nut, there should be no traces of grease on the seating surface of the pivot bearing hinge, and tighten it to a torque of 80 N·m (8.0 kgf·m).
Install the wheel and tighten the dry bolts by hand. Lower the car onto the wheels and tighten the wheel bolts crosswise to 140 N·m (14.0 kgf·m).
Loosen the lock nut (2, see Fig. 12.21) transverse steering rod on the left and right sides. By turning the transverse steering rod by the hexagon (3), set the positive toe-in angle of the wheel. Make sure that the boot on the rod does not turn. Tighten the lock nut to a torque of 51 N·m (5.1 kgf·m).
Attention! Adjustment of the steering wheels must be carried out on both steering rods simultaneously. The ends of the transverse steering rods must not have any gaps.
