Hi guys can you assist me. My e90 330i auto has developed a shudder from the rear. This only shudders at low revs when you accelerate then dies out as the revs pick up. It does not shudder at speed either. I have checked the gearbox oil seems fine. I have checked the prop bearing seems fine. I have checked the prop shaft rubbers that seems fine. I have seen there seems to be a sign of slightly worn control arm rubbers /stabalizer links at the rear. Could this cause the shudder at low revs when accelerating or do I check other arears on the rear end.

There is only 3 places the problem can come from, ie gearbox, propshaft or rear suspension. My money would be the propshaft as it will cause a shudder when the guilbo goes. Had this on both my previous E36 and E46.
Have you checked for cracks inside the guilbo as it might still be one piece but flex when it is having the most torque (from standstill to driving) sent to it. Like when it is going at a speed and suddenly you want to accelerate and the guilbo rubber is worn and flex a bit the propshaft will turn first and with some degrees prior to the rear diff catching up and once going with less throttle input it will be less severe.
