Lubrication Of The Steering Shaft

4700 mm 46.04.001

    Important: Only steering shafts with zerk fittings should be lubricated. Shafts without zerk fittings come with grease sealed inside and should not be greased.

    Important: Some vehicles may have additional U-joints on the steering column or stubshaft. These should also be lubricated at this interval.

  1. Open the hood and locate the lower steering shaft U-joint grease fitting.
  2. Using a clean rag, wipe all dirt from the grease fitting.
  3. Using a pressure gun, apply clean grease at the grease fitting until old grease is forced out of the seals. Use multipurpose chassis grease NLGI Grade 2 (8% 12-hydroxy lithium stearate grease) or NLGI Grade 1 (6% 12-hydroxy lithium stearate grease); Grade 2 is preferred. See Fig..

  5. Using a clean rag, wipe all dirt from the grease fittings.
  6. Using a pressure gun, apply clean grease at both grease fittings until old grease is forced out of the seals. Use multipurpose chassis grease NLGI Grade 2 (8% 12-hydroxy lithium stearate grease) or NLGI Grade 1 (6% 12-hydroxy lithium stearate grease); Grade 2 is preferred. See Fig..
