My 1992 Lumina Euro is making a loud clunking noise in the back right tire when I go over large bumps in the road. Most of the people I have talked to thinks it's a wheel bearing problem, but some doubt that. If I grab the wheel by the sides and rock it back and forth, the sound is generated...if I do this on any other wheel, it does not. Car milage is 63000. Any help will be appreciated.

Does the wheel actually move when you rock it? If it does then it is the bearing assembly.

yes it has some give and play in it...where the other wheels do not. this wheel is abs, how hard is it to replace the bearings?

Its been about a year since I last worked on one of those so I do not remember the specifics but i do not remember it being very difficult.

if it's not the bearing, any clue as to what it could be?
