Hey guys, I've got an issue in my '05 330xi, vibration only occurring under acceleration, worse in higher gears especially when accelerating from low in the rpm range, vibration feels like it's coming from right under me/center of car. Mechanic said the rear u-joint for the rear Driveshaft is bad, all rear bushings, CSB and guibo look fine.
Are xi and i Driveshafts interchangeable? I have an e46 328i Driveshaft lying around and would much prefer to use that instead of having to try and source an expensive replacement. Thanks for the advice!
Not interchangeable. XI is much shorter, use a different CSB, and the slip yoke is backwards. Because of the transfer case, the driveshaft actually starts right underneath the arm rest where non XI drive shafts start under the gear shifter. It is very common on all E46's to have the rear-most U joint go bad.
