1986 BMW 325 drive shaft makes noise (like spinning un-even) between 1st gear and 2nd gear then stops and drives fine was told this was a bearing can this be changed easily or will it require a shop to do this work.

do you mean the shaft from g/box to axle ,or shafts to rear wheels?

sounds like its comeing from the shaft to the rear wheel i can feel it hitting on the bottom of the console between the 2 front seats inside the car not hard or loud but can tell. The last owner said he had a shop replaced the top bearing but not the bottom bearing and thanks the bottom is now going out.

it's your driveshaft causing the noise and vibration and while the centersupport is probably broken, these break for a reason........the center and rear u-joints begin seizing up causing rapid speed chages in the shaft, quickly destroying the rubber carrier of the support. replacing just the support/center bearing may give you temporary relief but the u-joints are likely also bad. the best place to obtain a rebuilt here in the NW is 'Drivelines NW' in Portland, OR. this can be do-it yourself but it's not easy [exhaust must be lowered/removed] and the alignment of the replace centersupport fore/aft is important.
