You should repack the bearings with MIL-G-81322 grease. Spread a thin layer of grease on bearing cups. Inspect the rubber grease retainers for evidence of deterioration. Inspect the felt grease retainers for deterioration, contamination, or water saturation. Replace them if necessary. Freshwater-saturated felt retainers may be dried and reused if they are otherwise serviceable. Saltwater contaminated felt seals must be replaced. You should presoak felt retainers with VV-L-800 oil prior to their installation. Reinstall the wheel on the aircraft according to the applicable maintenance instructions manual (MIM).

When you reinstall the wheel on the aircraft, the proper adjustment of the bearings is extremely important. The following general rules apply to wheel installation:

1. Tighten the axle nut while you spin the wheel with your hand.

2. When the wheel no longer spins freely, back off the axle nut one castellation (one-sixth turn). When properly installed and adjusted, the wheel will turn freely, but will not move sidewise.

NOTE: This procedure may vary from one aircraft to another. Some aircraft require a specific torque to be applied to the axle nut. In these cases, you should refer to the applicable MIM.

4. Install and lock the hubcap in place. There are some inboard bearings that do not need to be removed except to be replaced. These bearings are listed in table 3-2, Aircraft Wheels, NAVAIR 04-10-1.

When you perform tire and wheel maintenance, you should handle inflated and partially inflated wheel assemblies with the same respect and care as live ordnance because of the destructive potential of a gas under pressure.
