33–05 Oil-Filled Hubs Oil Level
Checking
WARNING
Be careful not to overfill the hubs. Overfilling may cause oil to be forced out of the hubs and to contaminate the brake linings and other brake components.
This could result in loss of vehicle control and lead to personal injury and property damage.
1. With the vehicle on a level surface, rotate the front wheels and allow the oil in the hubs to settle.
2. Chock the tires.
IMPORTANT: The oil level should be at, or no more than 1/4 inch (6 mm) above the level indicators on the hub caps.

In section 33-06 it indicates:

1. With the vehicle on a level surface, rotate the front wheels so that the front hub drain plugs are positioned downward.
2. Chock the tires.
3. Place suitable containers under the hubs, remove the filler plugs (in the ends of the hubcaps) and the drain plugs, and allow the hubs to drain completely. See Fig. 11.
4. Install the drain plugs and tighten 25 lbf·in (282 N·cm).
5. Add approximately 1 to 1-1/2 pints (0.5 to 0.7 L) of oil (80W–90 hypoid gear oil) to each hub.
6. Rotate the wheels, allow the oil to settle, and check the levels.
IMPORTANT: Fill the hubs to the level indicators on the hub caps, or to no more than 1/4 inch (6mm) above the indicators. See Fig. 11.
7. Install the filler plugs securely.
