Checking the Oil-Filled Hubs Oil Level
rv mm 33.05.000
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.
- With the vehicle on a level surface, rotate the front wheels and allow the oil in the hubs to settle.
- Chock the tires.
- If necessary, remove the filler caps (in the ends of the hub caps) and add enough oil (80W–90 hypoid gear oil) to bring the oil to the proper level.
- Rotate the wheels, allow the oil to settle, and check the levels again.
- Install the filler caps securely.
- Remove the chocks from 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.
