Hi guy's,

I have a vibration in my BMW and I can't find where it comes from.

When I drive 120/130KM/U my rear end is shaking and my passenger seat is vibrating. So I guess it comes from the rear end also because I feel nothing in my steering wheel.

Also when I launch really hard I feel a small//quick vibration in the rear end for like 1 or 2 seconds.

I did an inspection on the drive shaft and everything moves very good. The only thing I felt was a little bit of movement in the spline section when you trying to twist the 2 separate shafts with your hands.

What I already did:
Replaced flex disc front and rear
Replaced support bearing drive shaft for billet one
Replaced engine mounts + PU inserts
Replaced rear diff mounts + PU inserts
Replaced brakes and pads
Replaced wheels, straighten them + balanced

What i want to do:
Remove the front drive shaft to be sure that is not the problem (no costs)
Replace the drive shaft from the gearbox to the rear diff if needed.

Does anyone has a similar problem or have an idea where the vibration is coming from?

“Poorly stored” tires can have a “slight flatness”, here is something to consider (experienced on Mercedes for me)

Your problem might be your e-brake retaining clip.
Watch this video on youtube, maybe you will recognize the rattle sound on your car as well.
