so one of the bolts of my guibo seems to always come loose. ive replaced it with an oem bolt from a bmw shop and the vibration did go away. but now theres a slight vibration between 40-50 mph, i thought the bolt came off again but i jacked the car up took a look and its still intact. its not so bad i can drive the car but it does make the car a bit shaky while accelerating. at 60mph and above, you cant feel the vibration at all. what could be the problem? i know its hard to diagnose without taking a look, but a wild guess is either center support bearing or the driveshaft..

It sounds like a worn out CSB. I tore a CSB one time and it vibrated really bad under load at low speeds but went away at high speeds. I'd dig in there and check it out.Last edited by andyman2487; 09-04-2009, 05:42 PM. -

A bad/loose guibo will kill a CSB pretty quickly. I replaced my guibo one time with a cheap ass knockoff part, and after a few clutch dumps a bunch of rubber chunks were missing. The CSB failed almost immediately. That rubber web that holds the CSB is super thin and easily ripped.Comment
