<< A >> CALIPER ASSEMBLY REMOVAL
Secure the removed caliper assembly with wire, etc.
<< B >> DRIVESHAFT NUT REMOVAL
| CAUTION | Do not apply pressure to wheel bearing by the vehicle weight to avoid possible damage when driveshaft nut is loosened. |
Use special tool MB990767 to fix the hub and remove the driveshaft nut.
Scheme 40
<< D >> DRIVESHAFT REMOVAL
Use special tools MB990241 and MB990767 to pull out the driveshaft from the hub and knuckle.
Scheme 41
>>A<< STABILIZER BAR INSTALLATION
Install the stabilizer bar so that the protruding length of the stabilizer bar mounting bolt meets its standard value (A).
Standard value (A): 1 +/- 22.5 mm (0.0 +/- 87.06 inch)
Scheme 42
Scheme 43
- Be sure to install the driveshaft washer in the specified direction.
- Using special tool MB990767, tighten the driveshaft nut. NOTE: Before securely tightening the driveshaft nuts, make sure there is no load on the wheel bearings. Otherwise wheel bearing will be damaged.
<< A >> HUB REMOVAL
| CAUTION | When the hub has been removed, always replace the wheel bearing with a new part because wheel bearing frictional surface will be damaged when removing the hub. |
Use special tools MB991017, MB991056 or MB991355, MB991001 (MB990998) to pull out the hub from the knuckle.

Scheme 47
- Crush the oil seal in two places so that the tabs of the special tool will be caught on the wheel bearing inner race (outside). CAUTION: When removing the inner race (outside) from the hub, be careful not to let the hub drop.
- Remove the wheel bearing inner race (outside) from the front hub by using special tool MB990810.
- Install the inner race (outside) that was removed from the hub to the wheel bearing, and then use special tools MB990935, MB990938, MB991056 or MB991355 to remove the wheel bearing.
Scheme 48
- Fill the wheel bearing with multipurpose grease.
- Apply a thin coating of multipurpose grease to the knuckle. and bearing contact surfaces. CAUTION: Press the outer race when pressing-in the wheel bearing. Otherwise the wheel bearing will be damaged.
- Press-in the bearing by using special tools MB990938, MB990935, MB991576.

Scheme 50
- Tighten special tools MB991000 (MB990998) and MB991017 to the specified torque, and then press the hub into the knuckle.
- Rotate the hub in order to seat the bearing.
- Measure the hub starting torque by using the special tools MB990326 and MB990685. Limit: 1.8 N.m (16 in-lb)
- The starting torque must be within the limit and, in addition, the hub rotation must be smooth.
Scheme 51
- Measure to determine whether the end play of the hub is within the specified limit or not. Limit: 0.05 mm (0.002 inch)
- If the starting torque and hub end play are not within the limit range while the nut is tightened to 29 +/- 245 N.m (21 +/- 181 ft-lb), the bearing, hub and/or knuckle have probably not been installed correctly. Replace the bearing and re-install.
