Caution! When installing the steering gear, it is necessary to use new steering gear mounting bolts, new ball joint nuts, center tie rod and transverse tie rod, as well as new rubber coupling mounting bolts.
Removal
Steering gear with power steering system
1 – steering gear; 2 – steering column; 3 – central steering rod; 4 – transverse steering rod; 5 – supply and return hoses; 6 – bolts
Hose connection points to the steering gear
1. Apply the parking brake, then raise the front of the vehicle and secure it on stands.
2. Set the front wheels to the straight-ahead position and in this position lock the steering column with the steering column lock.
Caution: After removing the steering gear, do not turn the steering wheel.
3. On models with power steering, use clamps to pinch the feed and return hoses near the steering gear. Label the hoses, then unscrew the union nuts and disconnect the feed and return hoses from the steering gear (see fig. Power steering gear, Hose connection points to the steering gear). Plug the ends of the hoses and the holes in the steering gear.
4. Using paint, mark the relative positions of the lower end of the steering column, the rubber coupling, and the steering gear pinion shaft. On some models, the heat shield must be removed from the steering gear to access the rubber coupling.
5. Loosen the rubber coupling mounting bolts and move it onto the steering column until it is removed from the steering gear shaft.
6. Unscrew the nuts securing the ball joints of the transverse tie rod and the center tie rod to the steering knuckle. Using a puller, remove the ball joints of the steering rods from the steering knuckle.
7. Remove the three bolts securing the steering gear located under the wheel arch and remove the steering gear from the vehicle.
Repair
1. Check the condition of the steering gear for wear and damage. Repair of the steering gear must be carried out at a service station. You can only replace the steering gear sealing ring yourself.
Installation
Centering the steering gear on early models (before 1990)
1 – steering gear; 2 – piston; 3 – gear; 4 – locking screw
Alignment of mark on steering gear pinion with mark on steering gear housing on 1990 and later models
1. Before installing a new steering gear, the steering gear must be centered.
2. On early models (before 1990) unscrew the plug and the sealing ring located on the side of the steering gear assembly. Then rotate the gear to a position where the centering hole aligns with the recess in the plug. If there is a cone locking screw, screw it in so that the steering gear pinion is securely locked (see Fig. Centering the steering gear pinion on early models (before 1990)).
3. On later models (since 1990) align the timing mark on the steering gear pinion with the mark on the steering gear housing (see fig. Alignment of mark on steering gear pinion with mark on steering gear housing on models since 1990).
4. Install the steering gear in place. Align the marks made before removal (when reinstalling the steering gear) or check the correct installation of the gear (when installing a new steering gear) and, moving the rubber coupling to the steering column, connect it to the steering gear shaft.
5. Secure the steering gear with new bolts, tightening them to the specified torque.
6. On early models, remove the cone bolt that secures the gear and replace the plug and O-ring.
7. Secure the rubber coupling with new bolts, tightening them to the specified torque.
8. Insert the ball joint pins of the central and transverse steering rods into the steering gear pitman arm and secure them with new nuts, tightening them to the required torque.
9. On models with power steering, connect the hoses to the steering gear and secure them with the union nuts, tightening them to the specified torque. Bleed the air from the power steering hydraulic system.
