    your car lowered? if so, you need engine mount spacers or shorter axles.

    then it's 95% likely to still be your shafts, the inner joints are probably loose, atleast one of them

    Exact same thing that was wrong with mine. Passenger side tripot (inner) joint was all chewed up. Dealer had "fixed" a leaking boot under warranty, and here's what I think of their fix.
