i have a 2008 MCs cabrio and after i get pass 35mph i hear what sounds like a wobble in the back, thats the best i can describe it, but there is no vibrations or anything and it doesnt get any louder when going faster. its driving me nuts and cant find anything wrong. any help or suggestions what it can be??

thx mike

 

Check your wheel bearings This sounds similar to the issue I fixed this weekend on my sister's 2006 cooper S. I had to replace both front wheel bearings to get rid of the noise.

 

Ok thx mine sounds like its in the back so i will start there and check the fronts. My car only has 32,000 on it seems kinda fast for bearings to go.
