The axial movement of the tip relative to the finger should be 1-1.5 mm. This movement indicates that the pin bushing is not wedged in the thrust tip socket and moves with the pin, compressing the spring. Replace jammed bushing.
Shaking the steering wheel in both directions, check by touch that there is no free play in the steering rod joints. If free play is felt in the ball joint, replace the tie rod end or tie rod assembly.
Check up a condition of protective caps of spherical hinges of steering draughts.
If the protective caps are in good condition and keep the inside of the hinges clean, then the service life of the latter is practically unlimited. If moisture, dust, etc. gets into the hinge parts wear out prematurely.
The cap must be replaced if it has cracks, tears, and also if the lubricant penetrates outward when squeezing it with your fingers.
Checking and adjusting the clearance in the steering gear worm bearings
Set the front wheels to the straight-ahead position, and by turning the steering wheel in either direction, check if the distance between the end of the crankcase does not change 7 (rice. 5-2) and label «IN», applied to the steering gear worm shaft.
A change in distance is a sign of clearance in the worm bearings.
To adjust the clearance in the worm bearings, turn the steering wheel to the left side by 1-1.5 turns, unscrew the bolts securing the bottom cover 19 and drain the oil from the steering gear housing. Remove the bottom cover, remove one of the shims 18 or replace it with a thinner one.
Note. Shims are supplied as spares in 0.10 and 0.15 mm thicknesses.
After securing the bottom cover, check again if there is any axial movement of the worm in the bearings. If there is no movement, pour 0.125 liters of transmission oil TAD-17i into the crankcase of the steering mechanism.
Check the steering force by placing the front wheels on a smooth slab. It should not exceed 196 N (20 kgf), 245 K* (25 kgf) *.
