Bad vibrations in reverse... any ideas? - Benzworld.org - Mercedes-Benz Discussion Forum

Starting yesterday I noticed that when I put my SLK in reverse ('98 230 with auto) the whole car shakes. I am not talking about a small vibration, I mean the car shakes like it is going to fall apart. In drive, it feels fine. This occurs with the car sitting still or moving backwards, anytime the transmission is on "R". Neurtal is also OK.

Anyone else have this problem or hsve any ideas what might cause it? I am going to take it to the dealer as soon as I can (of course this happens on labor day weekend...) but I was curious if anyone else had this happen. I have stopped driving it since it happened, because I am nervous that it is going to get worse.

Thanks in advance

no one has any ideas...

I hope my transmission is not shot...

I'm just guessing, but do a search for motor mounts. I remember people complaining of harsh vibration, but I can't recall if it was in any particular gear.

Good memory. That is the best guess I can come up with at this point.

search function isn't working for me. here's a quick list I got from another forum.

I do remember people talking about motor mounts, it just seems weird that it is so much worse in reverse.

Oh well, I guess I will find out the hard (and expensive) way when I take it to the dealer.

Use advanced search in Google using the URL from this site.
I did a rough one above.

Just an update incase anyone was interested.
The dealer found two problems, one was in fact the motor mounts (which were completely trashed, all of the oil sprayed out of them) and the second was a leaking rear differential (honestly, I am not sure what that exactly indicates...).
Total cost was 1500$, my extended warrentee is only covering 650$ (the motor mounts are a wear and tear item).

Since I didn't diagnose the differential problem, I won't send you a bill.[:D]

I hate that so much of the cost is out of pocket, but sounds like it should be a simple fix. When is it going to be taken to the shop?

Getting fixed right now. Hopefully I will have it back tomorrow. I am driving my friends Mazda 626 right now... lets just say I miss my SLK.
