I have a 2000 Malibu with 124K miles that for about 4 months has developed a buzzing/growling noise in the drivetrain when driving. The noise changes with the wheel speed and gets loudest when steering left. I first suspected wheel bearings, so I replaced the right side but it didn't help. I just replaced both axles and still have the noise. I also just got new tires today (they were getting bald). Still no change in the noise. There is no evidence of transaxle leakage and it shifts very smoothly, so I have not checked the fluid level yet. Even with me doing my own work, this is getting expensive. Anyone got any ideas of what is wrong?

Everything but the lt wheel bearing?

I can't remember if I swapped that or not. I know I pulled the hub out with the intention of putting the old right side one in it's place, since there was nothing wrong with it. I just can't recall if I carried out my stupid plan. Shoot. Lousy A.D.D. :banghead: :uhoh:

It was the left hub bearing. I would be more upset about replacing all that other stuff if I wasn't giving this car to my daughter for college.
