Remove the front brake caliper with the brake pads. Do not allow the caliper to hang on the high-pressure hoses.
Attach the 67.7834.9507 tool with the indicator (Fig. 4-4) to the steering knuckle so that the indicator leg rests against the wheel hub as close as possible to the adjusting nut. While turning the hub in both directions, simultaneously move it along the steering knuckle axis with the 67.7820.9521 lever (from and to oneself). Measure the amount of movement (gap) using the indicator.
If the gap is more than 0.15 mm, adjust it in the following order:
- unscrew the adjusting nut from the outer hinge housing tailstock;
- install a new or used nut, but on another car, and tighten it to a torque of 19.6 N·m (2 kgf·m), while turning the hub in both directions 2-3 times to self-align the roller bearings;
- loosen the adjusting nut and tighten it again to 6.86 N·m (0.7 kgf·m);
- make a mark B on the washer (Fig. 4-5), then loosen the nut by 20-25° until the first edge A coincides with the mark;
- lock the nut in this position by pressing the notches on the neck into the grooves on the end of the outer joint collar shank.

After adjustment, the bearing clearance should be within 0.01-0.07 mm.
