    What Is The Sign Of Transmission Mount Failure?

    What Is The Sign Of Transmission Mount Failure?
    I have been trying to solve an annoying knocking noise from the rear
    of my 15 yr old E30 318i Auto since I bought the car 3 mths back.

    I have todate changed the driveshaft,center bearing,trailing arm
    bushes and rear axle bushes.

    My car is much quieter now but the knocking noise remains.....it seems
    to happen when I slow down or suddenly take my foot off the
    accelarator.

    My next project is the Transmission @ Motor Mount/Tranny bushes?

    Any advise?

    Thanks.

    A common symptom is that the car jumps around when backing, particularly
    backing uphill. If it is difficult to get a smooth launch in reverse on a
    hill, or anytime, then this is a sign of a broken mount. By your
    description, I don't think you have a bad mount. I am worried that you might
    be having something ready to let go in the differential.

    Could be something simple like the exhaust box rubbing on the bodywork??
