I dig my "new" 1995 E320 Wagon but have 2 separate noise issues in the rear.
First, there is a creaking noise from the shocks. This is at low speeds, when turning a corner, when backing out of the driveway, etc. Annoying, yes, but tolerable if necessary.
The second one is driving me crazy. When I hit any kind of ripple in the road, a crack in the pavement, whatever, I get a thud from the passenger rear. At first I thought that something was loose in the cargo hold so I went back and checked everything: tools, jack, spare, all seem secure. As does the hatch: it is closing and locking down firmly.
My mechanic said that he cannot find anything with the shocks or the SLS system that is causing the noise.
I do have the third seat option, and I'm wondering if that's the cause. I can't seem to lock it down even though I see a keylock underneath the pull-up handle. How is this supposed to work? When I tinker with it, I find that it's actually hinged and pops up???
Just some guidance on how the lock-down is supposed to work would be great. Or if there is something else that is causing the noise?
