Rear end moves... back and fort!

[pedro]

Hello guys! I'm worried and really need your help. Everytime I drive my car and start braking to stop completely, the rear end makes a clunk you can barely hear and it feels as it moves back and fort. It moves only once back and fort, just before you stop. What could be causing this problem?

You sure that clunk isn't just your brakes? The rear drums on my Mustang used to clunk when you stopped at low speeds, and occasionally would lock up on wet roads.

you might have some rear control arm bushings or u-joint issues. Slide under it and pull on everything and see if something is loose.
