  1. Clean area around oil filler screw (50 g).

    IMPORTANT Only carry out the oil level check at interior temperature and not on a rear axle center assembly which is at operating temperature. Otherwise, when the rear axle differential is at operating temperature, required oil could escape.

  2. Remove oil filler screw (50 g)

    IMPORTANT Replace oil filler screw (50g).

  3. If necessary collect oil running out and allow to run out until oil only drips out of opening.

    G04734723
  4. Check oil level.

    IMPORTANT When the oil level is correct, the oil reaches the lower edge of the oil filler hole, refill if necessary.

    IMPORTANT The fully synthetic oil can also be used without reservations rear axle center assemblies which have been produced before 4.11.2001. Mixing old universal hypoid gear oil and new FE hypoid gear oil does not impair the basic functions such as wear characteristics, leaktightness, etc. at the rear axle differential, but on should, however, be avoided in the interest of better fuel economy.

  5. Clean the new oil filler screw (50 g) and the threaded hole in the rear axle differential with Loctite 7063 cleaning spray and a suitable rag.

    IMPORTANT The oil filler screw (50g) and tapped hole must be free of oil and grease.

  6. Apply about a drop of Omnifit sealing compound 100H on the second or third lower thread of the oil filler screw (50 g).

  7. Screw oil filler screw (50 g) immediately into the rear axle differential and tighten with specified torque TORQUE SPECIFICATION .
