need to know what gear oil to use to top up the rear diff and how.

Instead of topping it off, why dont you do a complete drain and fill. When I did it to mine the fluid came out looking like nasty chocolate milk LOL.

Only buy the fluid from an MB dealership as they use a special fluid. Maybe someone here can recommend a similar fluid that can be bought at a parts store but I was also told to only buy the gear fluid at MB.

At what interval or how often do we need to change the rear diff oil?

tastoto

Had mine serviced by MB dealership for $120. Noticed some rear end slippage & traction cntrl light flash when accelerating around turns...... no probs since.

Is there a drain plug and refill plug on the diff? I just hit 50k on my 03clk430conv and figured it was time. Also what's the capacity, less than 2qt?

tastoto

these a drain plug.
