Pontiac has new tires and still has a loud roar in the front, gets louder the faster you go. Sounds like a plane taking off or something.

Wheel bearing? If you turn left and it gets louder. It is the right wheel bearing. And vice versa.

Did it do this before things were replaced? Did you replace the half shafts (driveshafts)?

It could be the the wheel bearing...again, as you said. I also would like to know if you had the front end aligned when you changed the wheel bearing. If the tires have excessive wear on the outside or inside tread, you are out of alignment and BOTH wheel bearings need to be changed! It could also be the brakes wearing thin...check it out!

it could be a wheel bearing, or tire? but that a guess from a guy on the net that hasnt seen the car. See if you can find out front, rear, right, left.

ask a local mechanic to have a look and a test drive as no technician on any site can give you an answer only a guess and that is the wheel bearings

Tires, front diff bearings.

sounds to me like its a cv joint. if the rubber boot gets damaged in any way, dirt gets in there and really does some damage. check the boot really good. if you dont see any holes or anything it might just be the wheel bearing. id take it to a mechanic and ask him to just look at it. usually they wont charge ya.

The deeper or bolder the tread cut will cause more 'road noise'. The only solution would be to replace tires with manufature recommended tread design. You could also increase insulation under your carpetting or spray on "body insulation" on firewall to dampen the sound.

jack up front of car get hold of tyre an see if u get any play if u do u may get away with nipping them up a bit

It gets louder the faster you go and has gotten worse at lower speeds over the past month. Its a front wheel drive SUV and I had the bearings changed out last month. It is loud as all get out
