Adjusting the clearance in the steering worm bearings (VAZ-21051)

1. Set the front wheels to the straight-ahead position and, by turning the steering wheel in both directions, check whether the distance between the end of the crankcase 7 (see Fig. Section of the steering gear housing) of the steering gear and the tip of the steering shaft. A change in distance is a sign of clearance in the worm bearings.

2. To adjust the clearance in the worm bearings, turn the steering wheel to the left by 1–1.5 turns, unscrew the bolts securing the lower cover 19 and drain the oil from the steering gear housing. Remove the lower cover, remove one of the adjusting linings 18 or replace it with a thinner one.

Attention! Adjusting shims are supplied as spare parts with a thickness of 0.10 and 0.15 mm.

3. Having secured the lower cover, check again for axial movement of the worm in the bearings. If there is no movement, pour 0.215 l of TAD-17i transmission oil into the steering gear housing.

4. Check the steering wheel turning force by placing the front wheels on a smooth tile. It should not exceed 196 N (20 kgf).
