In order to help you better, I need more information. Please answer all my questions and we can narrow down the problem instead of quessing the answer. Let's start with the unanswered questions. 1) Is your power steering level full? 2)Does it make the noise sitting still, wheels not moving in drive? 3) Have you checked your brakes to see if nothing is rubbing and lining is not on wear indicators? 4) Is there any vibration on acceleration? 5) Is there a clicking noise when turning? 6) Does the noise change when turning side to side while moving?
Get a stethoscope and try to determin exactly where the noise is comming from. You could also use a long screwdriver and listen on the handle end. It would also serve you well to get a trans dipstick and check your fluid level.
Did you check with a stethoscope and find where the noise is comming from?
I had one of these Cavaliers bearing only last one month then the noise came back, another bad hub bearing.
There is no dipstick for the newer model Automatic transmission Cavaliers, however, There is a red fill cap on the drivers' side on top of the transmission. The only way to check fluid level is to jack up the car, making sure it level with a jack stand on each side of the car, and remove a small plug from the side of the transmission, underneath the car. It will be small and in an American size. It is either a 3/8" or a 7/16" size plug. Once it is removed, fluid will drain out if it is overfilled. Once there is no more fluid coming out, it is at it's proper level. If there is none coming out, then add more until it comes out and levels off. It has a capacity of about 11 quarts for the 4 speed models. The 3 speed models have about 7 quarts.
