Clunk when Moving in Reverse

E91 Hoarder · 07-15-2021, 02:43 PM

When I shift into reverse and start moving I hear slight clunk. May this indicate any potential issues? Car is 2012 E70 35i.

I am new to E70, coming from E92, having manuals all my life. Any advise is appreciated.

Where is the clunk coming from? Front, rear, underneath where transmission/transfer case would be?

The clunk is coming from underneath, seems like where transmition/tr case is.

Any updates? Getting worse? Fixed?

No, have not addressed it. Still there. not completely sure what it is. Trying to find another e70 to compare.

I have the same thing happen. A soft think and a jerk after placing it in reverse, before moving. I have the v8. E70 2007 89k miles. Had the dealer look at it, and they said they could not find anything wrong.

I know a few folks recommend doing a transmission fluid flush/change or maybe transfer case fluid change as the car ages. The local dealer is not recommending it though.

Bump…..Curious if anyone has an idea about what is going on here? Much appreciated.

Internals on transmissions usually do not clunk and if they do, it is loud and forceful.
I am going to bet you have 1 of 3 things:
Struts and strut mounts are worn
Engine and or transmission mounts are worn
A-arm bushings, ball joints, or tie rod ends are worn.

One other possibility is the bolts connecting the undercarriage to frame are a slight bit loose, but this is unlikely and usually only a result of having those previously removed.

Drive it over an inspection pit, get underneath it and see/hear what moves when it is placed into reverse...

Could be as simple as a bad trans or engine mount. They do go bad, especially at the age of your car. rubber doesn't last forever.
