Detroit™ Axles

rv mm 33.01.000

Notice: Use regulated pressure when lubricating the knuckle assemblies, otherwise damage could result to the knuckle caps.

On the front axle, grease fittings are on the top and bottom caps of each knuckle.

  1. Park the vehicle on a level surface, shut down the engine, and set the parking brake. Chock the tires. When lubricating upper and lower knuckle assemblies, do not raise the front axle.
  2. Wipe the grease fittings clean.
  3. Apply multipurpose chassis grease, NLGI Grade 1 (6% 12-hydroxy lithium stearate grease) or NLGI Grade 2 (8% 12-hydroxy lithium stearate grease), until new grease is seen at the junctions of the axle beam and knuckles. For locations of grease fittings, see Fig.; for grease exit points, see Fig..
