Front Axle Installation Details
1 - Trailing arm; 2 - Frame; 3 - Shock absorber; 4 - Diagonal bar; 5 - Brake line; 6 - Anti-roll bar; 7 - Transverse steering rod; 8 - Steering knuckle; 9 - Reducer (differential); 10 - Coil springs; 11 - Bolts; 12 - Assembling the front axle; 13 - Rubber bushings; 14 - Cardan shaft
Removal
1. Drain the oil from the front differential (see Chapter Routine care and maintenance).
2. Separate the cardan shaft (14) from the connecting flange of the main gear drive pinion and tie it to the frame.
3. Loosen the nuts securing the lower shock absorber supports (3).
4. Loosen the diagonal bar (4) to the frame.
5. Disconnect the brake lines (5) - immediately plug the open ends of the lines to minimize loss of hydraulic fluid.
6. Disconnect (and seal it immediately) hydraulic lines from the differential lock actuator cylinder.
7. Disconnect the wiring from the differential lock pressure switch.
8. Unscrew the contact pads of the brake pad wear sensors.
9. Remove the wheel sensors and electrical wiring located near the front axle assembly.
10. Remove the anti-roll bar (6) assembly with the struts.
11. Remove the cotter pin and loosen the castellated nut securing the steering trailing arm (7).
12. Press the transverse rod (7) out of the steering arm (8).
13. Disconnect the trailing arms (1) of the suspension from the frame (2).
14. Raise the vehicle so that the coil springs (10) can be removed (see Section Removal and installation front suspension springs).
15. Loosen the bolt (11) securing the diagonal rod (4), then move the axle assembly (12) forward and remove it from under the vehicle.
Installation
1. From the front, place the axle assembly (12) under the vehicle.
2. Install the coil springs (10) (see Section Removal and installation front suspension springs).
3. Install (but don't delay yet) bolt (11) for fastening the diagonal bar (4).
4. Lower the vehicle so that the longitudinal arms (1) can be seated in the frame.
5. Install the rubber bushings (13) and tighten the nuts.
6. Install the shock absorbers (3) and tighten their mounting nuts.
7. Tighten the anti-roll bar support fasteners (6).
8. Tighten the bolt (11) securing the diagonal bar (4) to the frame (2).
9. Connect the transverse steering rod (7) and tighten the castle nut of its fastening. Secure the nut with a cotter pin.
10. Connect the brake lines (6) - make sure that the lines are at least 20 mm away from the springs in any position of the front wheels.
11. Connect the hydraulic lines and electrical wiring to the differential lock actuator cylinder.
12. Connect the wiring to the contact pads and brake pad wear sensors.
13. Connect the propeller shaft (14) - ensure that the NEW self-locking nuts are tightened to the required torque.
14. Fill the differential with oil (see Chapter Routine care and maintenance).
15. Bleed the brake system (see Chapter Brake and auxiliary systems) and check the proper functioning of the brakes.
