9. Place the hub onto a clean work bench with the seal end
DOWN. Install the spacer.
앫 If the spacer has a tapered end: The tapered end should
face TOWARD the outboard end of the hub. Figure 5.3.

10. Before installing a wheel hub, ensure that all debris has been
removed.
11. Lubricate the outer bearing cone with the correct wheel-end
lubricant. Install the cone into the hub assembly. Figure 5.4.
Figure 5.4
You must apply grease to the bearing journals to prevent
fretting corrosion, which could result in damage to
components.
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
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.
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.

앫 If a lubricant fill hole is available: Lubricant can be
installed after assembly.
