135i low rpm Vibration (driveshaft

[dsocold]

To start with my rear end is completely new ( wheel bearings, all new bushings and ball joints, m3 arms, m3 subframe mounts, new oem diff mounts.

Now the problem, It only occurs from 1500-1800 rpm and it feels like a vibration and sometimes its a pretty darn stong vibration which shakes the whole rear in a very vibrate like fashion.. It basically happens under high load usually in gears like 1st, 2nd, and 3rd gear with light throttle at the desired rpm mentioned above but doesnt happen on gears 4,5,6. It also has at WOT a small vibration, almost like driving on a bent rim vibration from what feels like a driveshaft movement
I have 145k so i am suspecting its driveshaft related but i was always used to the hammer like sound from my old bmw when the center driveshaft bearing fails. I havent seen many guibo or center support bearing changes on the 135i so im wondering has anyone had anything similar or any insight.

Check your tires and wheels to make sure they're balanced well.

I definitely recommend going to get it checked out, DS failure can be pretty extreme even at low speeds.

All the more reason to check it. Misbalanced wheels can cause all sorts of weird vibration issues...badly balanced wheels are a possibility.
