Checking and preliminary adjustment before installation
Secure the steering gear in a vice with jaws covered with soft material.
Warning: When securing the steering gear in a vice, wrap the steering gear in a cloth and be careful not to damage it when the vice is tightened.
Gear preload
1. Measure the preload by turning the pinion with the special tool 09565-11100 one revolution every 4-6 s. Also measure the starting force of the toothed rack. Total gear preload: 0.6–1.3 Nm.
Warning: Measure the preload over the full stroke of the rack.
2. If the preload is not within the required value, first adjust the tightening torque of the plug and recheck the preload of the gear.
3. If adjusting the plug tightening torque does not produce positive results, check or replace the plug components.
Steering traction resistance
1. Perform 10 steering rod deflections.
2. Use a dynamometer to measure the force required to move the steering rod. Steering rod deflection force: 8–22 N.
3. If the measured value exceeds the standard value, replace the steering tie rod assembly.
Caution! If the measured value is below the nominal value and the steering rod turns smoothly and without play, it can be installed on the vehicle. However, if the measured value is below 4.3 N, replace the tie rod.
Checking the corrugated protective cover
1. Visually inspect the corrugated protective cover for damage and deterioration of its properties.
2. Make sure the protective cover is installed in the correct position.
3. If the corrugated protective cover has defects, replace it.
Disassembly
1. Remove the tie rod end from the tie rod.

12. Remove the spring, stop and bushing from the steering gear housing.
13. Remove the two bolts and remove the valve body.
14. Using a screwdriver blade, turn the rack stopper clockwise until the end of the locking ring comes out of the groove in the steering gear housing.
15. When the end of the locking ring comes out of the hole in the rack cylinder housing, use a screwdriver blade to turn the steering gear stopper counterclockwise and remove the locking ring.
16. Remove the O-ring from the rack bushing.
17. Remove the oil seal ring from the rack bushing.
18. Using a plastic hammer, knock the valve body out of the casing.
19. Using special tool 09565-21000, remove the oil seal and ball bearing from the valve body.
20. Remove the ball bearing from the steering gear housing.
Warning: Be careful not to damage the valve cylinder in the steering gear housing.
21. Using special tools 09573–21200, 09555–21000, remove the oil seal from the steering gear housing.
Warning: Be careful not to damage the rack cylinder in the steering gear housing.
Checking the toothed rack
1. Check the rack for damaged or worn teeth.
2. Check the oil seal contact surfaces for damage.
3. Check the rack for deflection or twisting.
4. Check the O-ring for any damage or wear.
5. Check the oil seal for damage or wear.
Checking the valve gear
1. Check the valve gear for damage to the teeth or wear.
2. Check the oil seal contact surfaces for damage.
3. Check the sealing ring for damage or wear.
4. Check the oil seal for damage or wear.
