[B]I just bought a 2003 G3 6mt with 45000 miles. The car looks new and runs great but it has a loud roar from the left front wheel. I sounds like a wheel bearing. It has gold Brembo brakes on all for with plenty of pad. Not sure if I should change the bearing or look into the brakes. Has any body had this problem? If you think I should change it do you know where I can find one at a good price.

 

[b] odds are it is a bad tire. [/b{

 

If it were the tire would it roar t 15 mph?

 

43K miles is super low for it to be a wheel bearing. Previous owner would have to put that thing from some real serious and consistent cornering to blow out factory wheel bearings that quickly.

Almost all G35 Coupes have tire noise from the front tires as they wear. Turn your wheels all the way to one side and get out and look at the inside edge of the tires. Chances are that the front tires are feathered and worn only on the inside edge as a result of the aggressive stock alignment configuration.

Without changing your control arms to adjustable ones, expect to go through front tires about every 15K to 25K miles, depending on how hard you drive and what kind of tires you put on there. A real soft tire will wear out faster.

 

I had some nasty roar sound coming to a stop. It was "feathering" of my cheap Nankang tires. Infiniti put new wheel bearings and it didn't fix the sound. Only until they swapped front wheels that they determined that it was the tires. I got everything free since they did it under warranty but I ended up new tires.

 

Radar, before you kiss this ^ idea off check the condition of your front tires! Are the insides bald or close to it? Only time I've ever heard the roar described was days before installing my camber kit and replacing worn b-stones! If your tires aren't worn as described have your alignment checked...Gary

 

As someone who's changed 3 bad wheel bearings on my car (2 at 60K miles), the easier way to tell is to jack up the car and remove thw wheel. Remove the caliper and brake and grab the hub and spin.

A good wheel bearing will feel smooth and spin without any roughness.

A bad wheel bearing will feel rough to turn.

 

Hey Gary... what control arm/camber kit are you using? I've heard of a lot of people having issues with welds and quality control on some of the aftermarket adjustable control arm kits for the 03/04 G Coupes. Some were just installed upside down (apparently), but I was curious how you like yours and how well they are holding up and about how much you paid for them.

 

Gary you were right. It was the tires on the front. The guy I bought it from didn't do an alignment on it about 10,000 miles ago and the tires were cupping on the inside. Is the Camber adjustable? The car is all stock with 18" wheels
