2001 Chevy Impala

Ok i have a 2001 impala that has about 135000 miles and I am having an issue with diagnosing a noise problem.
first of all i was getting a bearing type noise from the passenger (right) front end. Figured it was a wheel bearings , so i replaced the wheel bearings , then it deadened the noise. Then i replaced the cv shafts, no difference, did the brakes all the way around, no difference. Wheel bearing started to go bad again and replaced it again , and the noise deadened again. Then my transmission went out and put the new transmission in it, and then replaced the tires in the front , but still have a bad bearing type of noise. Anyone have any ideas of what else it may be.

Welcome to AF. How about the other side bearing or where both done?

they were both done within a week of each other

If you run the car ft wheels off the ground, safely of course, can hear a noise in either wheel?

the best and cheapest thing to do is call GM and complain. Their number is 1-800-222-1020. These transmissions are known to be defective but have yet to be recalled. I called today 6-21-2010.


Update
GM was useless

I got the transgo sk4t65e kit and used the accumulator springs and spacers, easy to do, cost about $65 for kit, and takes about an hour. drop pan, unbolt accumulator housing install springs, reinstall. works great
