    Bowling Ball in Trunk?

    I just started getting this issues, when I go around corners and hit any sort of bump I get what sounds like a bowling ball rattling/thumping around. I was also parked on a hill and held the brake and put it into reverse, started letting go of the brake and I didn't move at all. Any ideas? Bad diff is my thought.

    I'm not thinking so, maybe loose axle bolts, or possibly subframe, t/a bolts. Sounds like something is loose back there, check the RSM's as well.

        Rear shock mounts.

            I used to experience the same sound in my trunk. Turns out...it was the spare GSXR 750 engine that I had in it, haha. Note to self: find a way to secure the next engine I put in my trunk down so it doesn't put dents in my trunk lid from the inside
