recently, my car has started to make a strange sound when i brake in a new direction. Basically, when i reverse out of the drive, then hit the brakes, i get a slight clunk. Then, the first time i stop going forwards (at the end of the road) i get a slight clunk. it doesn't do it again until i change directions to reverse. i swear ive heard this before in other cars, but dont have any idea where to start looking. any ideas people?

Guibo? Its just a guess, but if it happens when changing from forward to reverse and reverse to forward the tension is realeased and force is then put on it the other way.

Diff guibo.....or CAB's. When have those been changed.

I have had a similar clunk coming from the front when changing directions (very slow in the driveway, going up and down for example). The car would also occasionally have a clunk upon applying brakes for the first time. Go forward 5 yards, hit brakes -clunk, go backward 5 yards hit brakes- clunk, etc...
T'was my lower ball joint on the front control arm. Had it replaced yesterday, and that clunk is gone.

Sounds like control arm bushings.

How about control arm itself (and its 2 anchor ball joints), not the bushing?

Bad control arm usually clunks when going over bumps or change of direction, iirc.
Bad CABs usually clunk when you stab the brakes.
Might be able to narrow it down by trying both of the above and seeing which one reproduces best.

Jack up the front end....grab the tire at nine and three.....if it moves....CABs are bad.
