Note. When installing, you will need new tie rod end nuts, steering gear mounting nuts, intermediate shaft pinch bolt, and pipe fitting sealing washers.
Withdrawal
1. Chock the rear wheels and apply the parking brake. Raise the front of the car and place it on stands (cm. "Lifting and placing the car on supports"). Remove both front wheels, then remove the screws and remove the engine crankcase protection.
2. Turn away nuts of hinges of steering draughts and take out fingers of hinges from rotary fists by means of a stripper.
3. Mark with a marker the position of the intermediate shaft coupling relative to the steering gear shaft.
Note. Some models already have marks on the gear flange and on the steering gear housing. Align these marks before disassembly (pic. 21.3).
4. Turn out a bolt of fastening of the coupling (pic. 21.4).
5. Pinch the power steering hydraulic hoses next to the hydraulic reservoir. This will help reduce fluid leakage. Tag hoses (for ease of reassembly), then unscrew the bolts of the pressure and return hose fittings. Remove sealing washers. Prepare for a fluid leak. Place a container under the hoses (pic. 21.5). Plug the ends of the hoses and the holes in the steering gear to prevent leakage of fluid and dirt from entering the hydraulic system.
6. Turn out bolts and nuts of fastening of the steering mechanism and take it out from under the car (pic. 21.6).
Repair
7. Inspect the steering gear for wear and damage. Make sure that the rack moves smoothly and without sticking throughout the entire range. Make sure there is no play between rack and pinion. The steering mechanism is not repaired. In case of damage to its parts, it is necessary to replace the entire assembly. You can only replace rack covers, tie rods and tip pivots. The procedure for replacing these parts is described later in this chapter.
Installation
8. Reinstall the steering mechanism and insert the bolts of its fastening. Screw new nuts onto the bolts and tighten them to the required torque.
9. Install new sealing washers on both sides of each hose, insert union bolts and torque tighten.
10. Align the marks made before removal and connect the intermediate shaft coupling to the gear flange. Insert a new tie bolt and tighten it to the required torque.
11. Insert axes of hinges of steering draughts in rotary fists, screw new nuts and tighten them the demanded moment.
12. Install the wheels and crankcase protection, lower the vehicle to the ground and tighten the wheel bolts to the required torque.
13. Bleed air from power steering hydraulic system (see paragraph 23).
