Unhappy 99 Pontiac Grand Am Front End Noise

Noise starts as soon as the vehicle moves, the noise is from the front of the car, the faster the car goes the louder the noise is. The noise can be described as a growl. When I turn the steering wheel to the left, the noise quits. When I turn the steering wheel to the right, the noise stays the same or gets louder. I thought the noise was because of a bad driver's side front hub assembly so I changed it. The noise is still there after installing new driver's side front hub assembly. I have inspected the passenger side hub assembly and it seems fine. I have inspected both cv joints for play and they also seem fine. Any help with troubleshooting this matter would be greatly appreciated. Thanks.

the noise you are describing sounds like bad whell bearings,when you replaced the r-front hub was it used or did it have a new wheel bearing in it also that type of noise carries how did you inspect the left hub?I could never tell a bad bearing by looking.and even turning will seem smooth but when they wind up with weight from the car on them they make noise!!Two othr things how many miles on the car and have you rotated the tires to see if the noise moves?you can rule out the cv joints as the either break or make a knocking noise when turning if they are bad!

The hub assembly was brand new made by Timken. This was installed on the driver's side front. I inspected the passenger side front by looking for play with caliper removed and then placing indicator on surface on hub asseembly and looking for more than 4 thousandths movement. I have 130,000 miles on the car. I do not have any knocking noises when turning, this is a constant noise. I can change the tone of the noise by moving steering wheel left to right but the noise is always there. I have always had a noise in this car but one day last week the normal noise got really loud. Could this be a driveaxle bearing in the transmission?

Possibly a motor mount, causing engine & transaxles to shift, and changing sound?

I also jacked the car and supported on jackstands, then I removed the tires. With car in drive, I gave the car gas the drivers side drive shaft and hub rotated and made noise but the passenger side hub / driveshaft did not rotate. I think it is coming from the driver's side of the car, but that is the side that I just replaced the hub assembly.

Grand Am front end noise - I have the same problem

Did you solve your problem with your grand am. I have exactly the same problem you are describing. I also had a crackling sound which was cause by the CV axle (that's gone now) but I still have the growling noise which gets worse as I accelerate and when I turn to the right? Did you ever solve this problem? I was going to change my wheel bearing because it sounds like a wheel bearing problem to me, but it seems like you did that and still have the same problem?

usually the transaxles have bushings not bearings. get an automotive stheathascope and put it back up on jackstands, taking care to level the car with the weight on the suspinsion, remove the wheels and tires, then run the car in gear and very carefully listen for the noise, you will probably need a helper to turn the steering and apply brakes to help isolate. don't lay under the car with out making sure it will not fall while turning the steering and running. my guess based on what you have done so far is sound transfer through exhaust or motor/transaxle mount from something else. Last thought, have you checked the bearing that is in the top of your struts. If it is bad this could allow noise transfer from the road to car body.

having same problem...

i just spent the morning changing my drivers side hub assembly (new) and the test drive revealed that the noise is still present. This does not sound like a motor mount problem. It sounds like a driveline problem, but not sure where/what it would be.

any ideas anyone??

oh yeah, something that the others didnt mention is that it throws "service vehicle soon", "Trac off" and "ABS" lights on my dash. which is why we all decided it had to be a bad sensor/hub assembly.

thanks

Have been fooled many time by a noise that sounded like one side and it was on other side. I would pull axel out of hub on other side and turn hub hand and see if it feels rough, etired few years ago don't know about lights maybe sensor loose or damaged.
