Attention! Attempting to reduce bearing clearance by over-tightening the hub nut will result in accelerated bearing failure.
When the bearing is pressed out, it is destroyed and replaced with a new one.
Withdrawal procedure:
- remove the steering knuckle as described above;
- install the steering knuckle on wooden supports;
- resting a suitable tubular mandrel only on the inner part of the hub flange, press it out of the bearing. If the hub was pressed together with the inner double bearing race, pull the race off the hub using a puller;
- remove the retaining ring from the groove on the steering knuckle;
- press out the remaining part of the bearing with a press, applying force to the inner ring of the bearing;
- thoroughly clean the steering knuckle and hub from grease and dirt, remove possible nicks and burrs with a needle file. Inspect parts for cracks or other damage. The bearing and retaining ring are replaced with new ones.
Installation order:
- make sure (if it is possible) presence of lubrication in the inner cavity of the bearing;
- lightly lubricate the surfaces of the bearing rings with grease;
Pic. 5.10. Pressing the bearing into the steering knuckle
- using a press, press the bearing into the steering knuckle using a mandrel with an outer diameter of 70 mm and an inner diameter of 66 mm, applying force to the outer ring (pic. 5.10);
- install a new retaining ring in the groove on the steering knuckle;
Pic. 5.11. Pressing the bearing onto the front wheel hub
- put the inner race on the hub and press the bearing onto the hub using a mandrel with an outer diameter of 48 mm and an inner diameter of 42 mm, applying a load to the inner bearing race (pic. 5.11);
- make sure that the hub flange rotates freely and remove excess grease;
- Install the steering knuckle as described above.
