If the repair of the suspension requires a complete disassembly of its components, then start it directly on the car, before compressing the suspension spring.
1. Bend the tabs of the locking plates, unscrew the caliper mounting bolts, moving it to the side, and fix the caliper so that it does not hang on the hoses.
2. Puller 67.7801.9514 remove the front wheel hub cap.

4. Carry out further disassembly after removing the suspension unit from the vehicle, fixing it on a workbench.
5. Loosen all nuts 1 (see fig. Left wheel suspension assembly fixed on a workbench for disassembly), remove the lock plates and knuckle arm; at the same time, the brake caliper mounting bracket 2 and the protective cover 3 of the brake disc are released.
6. Loosen pin nut 2 (see fig. Removing the upper arm) upper hinge, install tool 3 (puller 67.7801.9513) between the fingers of the ball joints and, wrapping the bolt of the puller, press out the pin of the upper hinge from the steering knuckle 1.
7. Unscrew the nut of the lower hinge pin and install between the hinge pins and stop 2 (see fig. Removing the lower arm) puller 67.7801.9513; while tightening the puller bolt, press out the finger and remove the lower arm from the knuckle.
8. When repairing the front wheel hub, use mandrels: 67.7853. 9526; 67.8953.9527; 67.7853.9525; A.74155.
9. The assembly of the front suspension units is carried out in the reverse order of disassembly.
10. Lubricate the front wheel hub bearings with LITOL-24 grease, as indicated in subsection 6.1.5.
11. Before assembling the ball joints of the suspension arms, put grease ShRB-4 or LITOL-24 into protective covers in an amount equal to 1/3 of the volume of the cover in a free state.
12. Tighten the nuts and bolts for fastening the suspension assemblies and parts to the torques specified in subsection 3.4.
