Thanks for answering my last question and all the other info I have gotten through MercedesSource by way of instructions and guides. I have new rotors that I aquired and the part number indicates that they go to the front of my 1984 300D. My question is that the old rotors (probably the originals)are bolted to the front bearing hub as you have confirmed. These new aftermarket rotors have no threads in the hub mating surface to accept the 5 mounting bolts that hold the old ones on. What gives? I have looked at other replacement brands also and see no way of fastening them to the hub.

Hi all. I purchased the injector pump rack dampner bolt from Mercedessource complete with instructions. The mention of an O-ring made me somewhat prepared for some kind of fluid to be leaking out as O-rings are usually sealing something off. I expected diesel fuel but oil leaked out of the hole. There was no mention in the instructions of any fluids leaking out of the hole when removing the old one but I had some oil leak out and was wondering if that was normal.

I own two wagons, an 82 and an 85. The 82 has rebuilt rear suspension in the form of new accumulators, shocks and leveling valve. The 85 has had the shocks replaced some time ago, but is now mushy and leaks down over a period of 12-24 hours. I'd like to perform a preventive maintenance inspection and performance test to determine the condition of the system and point to component failures. Where is a good place to start?
