- raise the front of the car and secure it on stands;
- remove the front wheels;
Figure 6.7. Fastening the device that prevents the hub from turning: 1 - cotter pin; 2 - cap; 3 - nut, 325 Nm; 4 - a device that fixes the hub from turning
- remove cotter pin 1 and remove cap 2 (figure 6.7), securing the nut that secures the drive shaft to the hub from loosening;
- using tool 4, secure the hub from turning and loosen and then unscrew nut 3 securing the drive shaft to the front wheel hub;
Figure 6.8. Location of the bolt (2) for securing the ABS sensor (1)
- unscrew bolt 2 and remove ABS sensor 1 (figure 6.8) from the steering knuckle;
Figure 6.9. Location of the caliper mounting bolts (1) and the nut (2) for fastening the ball joint pin of the lower wishbone to the steering knuckle
- unscrew bolts 1 (figure 6.9), remove the front brake caliper and tie the caliper to the body with soft wire. The caliper should not hang on the brake hose;
- remove the brake disc;
- unscrew nut 2 securing the ball joint pin of the steering knuckle to the lower wishbone;
- using a ball joint puller, remove the steering knuckle ball joint pin from the lower control arm;
Figure 6.22. Using lever 0622 to separate the ball joints of the steering knuckle, to remove the lower wishbone from the ball joint journal of the steering knuckle
- using the 0622 lever for separating the ball joints, separate the lower wishbone from the ball joint of the steering knuckle (figure 6.22). Be careful not to damage the protective cover of the constant velocity joint of the drive shaft;
Figure 6.2. Location of shock absorber strut mounting nuts: 1 - nut for fastening to the anti-roll bar link; 2 - nut for fastening to the steering knuckle; 3 - nut for fastening the steering rod end to the ball joint
- unscrew nut 3 (see Figure 6.2) fastening the ball joint journal of the tie rod end to the steering knuckle, being careful not to damage the protective boot of the constant velocity joint of the drive shaft;
- using a puller, remove the ball joint from the steering knuckle;
- mark the position of the bolts securing the lower part of the shock absorber to the steering knuckle;
- holding the bolts from turning with one key, use the second key to unscrew the nuts 2 (see Figure 6.2);
- remove the bolts securing the lower part of the shock absorber strut to the steering knuckle;
- with the steering knuckle tilted away from the vehicle, remove the drive shaft from the front wheel hub and secure the drive shaft to the vehicle body with soft wire;
- remove the steering knuckle from the vehicle, being careful not to let the drive shaft come out of the differential housings.
Caution! Never lower the vehicle onto its wheels with one or both drive shafts removed, as this will damage the wheel bearings. If it is necessary to place the vehicle on its wheels and move it with the shafts removed, install its outer joint instead of the drive shaft and tighten the joint mounting bolt to a torque of 325 N·m.
Install the steering knuckle in the reverse order of removal, taking into account the following:
1) When installing, replace the caliper mounting nuts and bolts with new self-locking nuts and bolts, applying a locking compound to the threads to prevent them from loosening;
2) Tighten the nuts and bolts to the following torques:
- tie rod end ball joint fastening nut — 50 Nm;
- fastening the shock absorber strut to the steering knuckle - 90 Nm;
- ABS wheel sensor mounting bolt - 9 Nm;
- hub mounting nut - 325 Nm;
- caliper mounting bolts to the steering knuckle - 105 Nm;
- brake disc mounting bolt - 10 Nm.
