Axle Hub Assembly: Reassembly
WARNING: This page is about a different variant/trim than selected.
- Fill the wheel bearing with multi-purpose grease. Apply a thin coating of multi-purpose grease to the knuckle and bearing surfaces. Using Brass Bar (MB990938), Installer Adapter (MB990935), and Base (MB991576), press in the bearing. See Fig 1 .
- Install snap ring. See Figure .
- Install dust cover.
- Install hub.
- Tighten Front Hub Remover and Installer (MB991000 or MB990998) and Front Hub Remover & Installer (MB991017) to 160-202 ft. lbs. (216-274 N.m) and press the hub into the knuckle. See Fig 2 . Rotate the hub in order to seat the bearing. Using Preload Socket (MB990326) and Torque Wrench (MB990685), measure the hub starting torque. The starting torque must be within 16 INCH lbs. (1.8 N.m) and, in addition, the hub rotation must be smooth.
- Measure the end play of the hub. Hub end play should be 0.002" (0.05 mm).
- If the starting torque is not within 16 INCH lbs. (1.8 N.m) and hub end play is not within 0.002" (0.05 mm) while the nut is tightened to 160-202 ft. lbs. (216-274 N.m), the bearing, hub, and/or knuckle have probably not been installed correctly. Replace the bearing and reinstall.
