Default Wheel Grinding

Hello, my front left wheel is grinding... the only problem is I don't know where exactly and what is causing it. It sounds kinda like I have a monster truck tire. It sounds like whatever is making the sound rotates. And it produces this sound regardless of whether the brake is applied or not. I thought it might've been the brakes so I changed them, but it didn't help at all... was a good time to change them anyways... Any ideas of what the noise is? Thanks!

Could be the wheel bearings. Lift the wheels off the ground. Grab either the top and bottom or both sides and shake (pull/push). If there's a good bit of movement, it's probably the wheel bearings are shot.

Did you check to see if the caliper piston is retracting when the brakes aren't applied?

The wheel moved a fraction of an inch. I compared this to the other front tire, which didn't move at all. Is this small amount enough to diagnose it as the wheel bearing? And I didn't check the piston, other than putting it back into place when I installed new brakes.

You wouldn't think that little bit of movement would be a bad bearing but it's enough to it it further diagnosed by someone with experience.

I went to a parts store, and they quoted the price to replace the bearings at around $70. Also, the guy at the shop said that they were "pressed", and I would have to take it somewhere to get the new bearings "pressed". Are there any other things I can check to see that may be causing this sound? I'm not too familiar with everything dealing with axles and steering, but I can't really afford to take it to a shop right now. Any suggesstions at all would be great. Thanks

After my last post, I read several other posts on this site and others about the ground cables keepings the wheel bearings from going bad. When I replaced my brakes, the ground cable on the drivers side was snapped off. I would've never made the connection.

Yep, been telling everyone I can and posted threads and pictures of that grounding wire. Make sure they are connected securely on both front wheels.

Hey their bjagd02,

How are your Tires? The reason I ask, back when I first bought my PT it came with some way cool high performance BFG Flame Cut Tires which I loved big time as they looked pretty cool. Problem was at around 33,000 miles or so I started developing a loud grinding like noise which I too thought was my wheel bearings so I replaced them but the noise still remained. It was then mentioned that the tires might be the issue which I was skeptical but after replacing them with a different tire and tread pattern the noise went away and everything was dead quiet once again. Their are not too many things as far as I am aware that can cause that kind of grinding noise that I am aware other than bearings or tires.

That's my two cents anyway. I wish you the best o luck on trying to troubleshoot and diagnose your problem.

if there are grounding straps on the front disk brakes.... do the rear disk brakes have them also?
