I've been out early morning today to open summer driving season
Had done a few sporty drifting laps and after some time when returning home I was faced with these new awful sounds coming from the end of my 325e 86':
1) when cruising (no gear engaged) >40kmh a strong chattering and a feel of vibration emerges from the rear of the car
if I engage a gear and accelerate or decelerate (stopping car with an engine) it almost disappears;
if I press the brakes - it almost disappears;
if I change the gear up/down, at the time when there is no gear I hear the chattering again.
Shortly, it seems that the chattering is coming when there is no tension in the drivetrain.
2) when starting from a standstill I hear CLANK! (or BANG!)
: then the car runs fine (until I reach middle speeds)...
I have inserted a viscous LSD differential a few years ago. Also had done a major rebuild of it (in order to make more lock) two years ago. And it worked great. Hope it's not a diff... I would suspect the diffs U joint, but then why it appears when cruising and not viceversa?
Hope for your help,
