Steering - inspection,
check and adjustment
General inspection
The steering system should be examined at any signs of mal-
function (rattle, excessive free play of the steering wheel or, on
the contrary, its hard rotation, and so on). The inspection is car-
ried out on the trestles or an inspection pit in the following order.
Clean the components of the steering mechanism and the
steering box. Place the wheels in position corresponding to
straight movement.
Turn the steering wheel in both directions, and ensure:
- the steering wheel free play does not exceed 5° (when mea-
sured on the wheel rim, no more than 18-20 mm). To perform this
operation use tool 67.8720.9501;
- there is no rattle in joints, connections and steering mecha-
nism;
- reliable fastening of the steering box and the slave arm
bracket (tighten the threaded connections if necessary);
- there is no free play in the tie-rod balljoint and in the slave
arm bracket, and there is no axial displacement of the worm
shaft;
- the steering wheel turns with the effort (with the front wheels
standing on smooth surface) not exceeding 196 N (20 kgf), 245*
N (25* kgf).
Check the tie-rod adjuster pins, ensure reliable tightening of
the clamps.
Inspect the balljoint and protective caps, as set forth below.
Inspection of the tie-rod balljoint
First, check the movement of the tie-rod ends along the pins.
For this purpose, move the end parallel to the pin, using a lever
and a support.
The axial movement of the end in relation to the pin should
be 1-1.5 mm. This will prove that the pin insert is not jammed in
the tie-rod end and it moves together with the pin, depressing the
spring. Replace the joint with a jammed insert.
Rotate the steering wheel in both directions, by touch ensure
there is no free play in the tie-rod joints. If the free play in the ball
is detected, replace the tie-rod ends or tie-rod assembly.
