    ok so my back part of my car vibrates and makes noice when im engine breaking below 3k.
    sounds like its from the back shaft/ rear differential area. what could be the cause? u-joint? or one of the shaft holders?

    jack it up and check every thing it could be a carrier bearing or u-joint or a bad axle or bearing just check every thing and go from there

    well i took my car to my buddies suspension shop and found nothing wrong with axels, rear end, or shaft. only thing we notice is the the rear sway bar is a little loose cause the bushings on the holder brackets are worn... could that be why?

    no that shouldn't cause it but maybe check all of your motor mounts one could be worn out or broke sending your vibration to the back and make you think its back there check the front and rear roll stops

    the term roll stops i am referring to are the front and rear motor mounts the keep the engine from rolling front wards or backwards like if you have the hood open and you rev the engine manually the engine is going to try and rotate backwards and the rear motor mount keeps it from doing this so if one of the roll stops are bad then it will make the noise your describing because the engine is jerking when you do that

    O OK... thanx for the explanation. as for the front and back mount they have the inserts and the engine does not really quick when i manually rev it... im going to change the bushings from my rear sway bar and see if that changes anything... ill let you know.
