    Rear Clunking Noise - Braking and Driving

    I have an issue with my 1986 325es. I am not really sure what it is, and I am a bit worried at this point. Basically, whenever I brake in gear, it makes a lound clunk seeming to come out of the rear. I accelerate and I can vaguely hear it. But I sense it is there. If I turn left or right, the sound is even stronger. I have figured out this only happens IN GEAR. I push the clutch in and it immediately stops. Pull it out, and the sound comes in again. I am hoping it isn't a huge problem where it is going to cost me thousands, like a new differential or, at thw worst, a new transmission. Please let me know your input. I will be taking it in to my high school class to look at it. Thank you!

    The first check would be all of the rear suspension parts and the differential mounting. If not that there is a problem in the drive train from the transmission back.
    The car makes it possible, but the driver makes it happen.

      Agree with Jim, start with the entire rear suspension - shocks/mounts, subframe bushings, etc. The way you describe it though, could be driveline related or a combination.
