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

4. If after that the steering wheel play still exceeds the maximum permissible value, then install the front wheels parallel to the longitudinal axis of the car with the engine off (pic. 13.2). Apply a force of 5 N in the direction of the steering wheel rim and check the play.
Rated value (with the engine off) – 10 mm or less.
5. If the backlash exceeds the nominal value, then remove the steering gear and check the moment of resistance to rotation of the gear.
