12. Use a fine abrasive to remove any light corrosion fretting on the
spindle. Clean and wipe with an oily rag. Cover the spindle with
standard Grade 2 grease. Both the bearing journals and the
seal journal must be well-coated. In severe environments, use
a Moly-grease to provide added protection.

Installation

Wheel Hub

WARNING
Fill the oil reservoir to the correct level. If the oil reservoir is
low, damage to the bearings can result, which can cause a fire
in the wheel-end assembly, or the assembly can separate from
the vehicle. Serious personal injury and damage to
components will result.
CAUTION
Do not support the hub on the spindle with only the inner
bearing and seal. Damage to the seal can result.
1. For drive hub installation only, place the hub horizontally and
remove the outer cone and spacer. Fill the oil reservoir with as
much oil as possible through the end of the hub with the axle
flange studs. Install the spacer and outer cone into the hub.
Use only lubricant approved by the component manufacturer.
Figure 5.5.
If a lubricant fill hole is available: Lubricant can be
installed after assembly.
