rv mm 35.05.000

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.

  1. With the vehicle on a level surface, remove the hub cap (also referred to as a beauty ring).
  2. Rotate the rear wheels so that the rear hub drain plugs are positioned downward.
  3. Chock the tires.
  4. Place suitable containers under the hubs, remove the filler plugs (in the ends of the hub caps) and the drain plugs, and allow the hubs to drain completely. See Fig..
