2. By turning the steering wheel slightly in both directions until the front wheels start turning, measure the free play (backlash) of the steering wheel on its rim. The maximum permissible value is 30 mm.
3. If the steering wheel play exceeds the maximum permissible value, check the steering shaft connections and steering rods for clearances. Repair or replace worn parts.

4. If after this the steering wheel play still exceeds the maximum permissible value, then set the front wheels parallel to the longitudinal axis of the car with the engine not running (Fig. 13.2). Apply a force of 5 N in the direction of the steering wheel rim and check the play.
The nominal value (with the engine not running) is 10 mm or less.
5. If the play exceeds the nominal value, remove the steering gear and check the torque of resistance to rotation of the gear.
