1. Make sure that the steering column locking lever is raised to the stop. Trying to move the steering wheel in the vertical plane, check the reliability of the steering column fastening by the locking mechanism. If the steering column moves, adjust the locking mechanism (see "Steering column locking mechanism - checking and adjustment").
2. Trying to move the steering wheel along the axis of the steering shaft, we make sure that there is no play in the steering wheel on the splines of the shaft and the shaft in the steering column.
3. To check for play in the steering, turn the steering wheel to the position corresponding to driving straight ahead. Place a flat-blade screwdriver on the instrument panel so that its blade is located next to the steering wheel rim. Turn the steering wheel to the right until the wheels start to turn (choosing backlash), and then to the left and, using a screwdriver blade as a guide, chalk, wire pieces or some other method, mark these positions on the rim. The play should not be more than 5° (or 18 mm) when measured along the outer part of the rim.
Note: Increased play indicates the need to find and fix the problem. As a rule, the first thing to fail in the steering system is the tie rod ends.
4. To check for play in the tie rod ends, have the assistant gently rock the steering wheel from side to side.
Place your hand on the junction of the steering rod and the suspension strut pivot arm so that your palm touches them simultaneously. When there is play in the steering rod end, you will feel the pivot arm shift relative to the rod.
5. Check the tightening of the coupling locknuts.
6. Repeat the check on the other side of the car. Replace faulty joints (see "Tie Rod End - Replacement"). If necessary, tighten the lock nuts.
7. When rocking the steering wheel from side to side, listen to the operation of the steering mechanism. A knock from the right edge of the steering mechanism indicates wear of the support bushing. Disassemble and repair or replace the faulty steering mechanism (see "Steering gear - removal and installation").
