Reverse drops in hard

[ufo8mycow]

when the car has been driven for a little while if i drop it into reverse it drops in hard with a clunk, does anyone know what the problem could be?

Yes. It sounds like the uni-joints in your tailshaft.

is that bad?

is that bad?

not really.

uni-joints are about $30 from an auto shop and easy as to remove/install.

search the "how to" section and there should be a writeup on how to replace a uni-joint
