    Kah-Clunk from the back of the car every time I let off the gas

    As posted, whenever I let on the gas, or get on the clutch, the back of the car gives this Kah-Clunk sound. It takes about 1-2 seconds after letting off the gas.

    I'm thinking some part has gone bad, any ideas?

    Technically three, but the one you need to check is the large one in the rear of the diff. Mine looks like this currently. Hopefully I can replace it this weekend without too much drama.

    I'm doing all three. I got the back one out; it's sitting overnight, I'll do the front ones too while I have the diff out.

    God bless youtube videos.

    Did you use a special tool?

    I have a Koch tool that’s available for rent that helps with the big one. Also RTABs. It won’t work for the two small diff bushings unless you drop the subframe.
