I swear it sounds like every bearing under my car is shot. This is a 2000 Camaro SS. The thing wails horribly above 10 mph and I cannot tell if the noise is coming from the front or the rear. I bought the car last year and I initially thought the noise was coming from the rear. Just pulled it out of storage and I swear the noise was coming from the front, then a few minutes later I couldn't tell where it was coming from. When I apply the brakes I am also hearing an even louder buzz/grinding sound, definitely up front.

Also, I have grabbed the wheel at 12 and 6 to test for play and there is none.

Please have a listen and let me know what you think. Thanks.

When driving does the sound change as you slightly turn the car left or right?

Kinda hard to tell in the video. Like posted above it will normally get better or worse if you turn left or right. Also if you have a temperature gun go for a cruise at highway speeds and then coast to a stop...check center hubs to see if there is much of a temp difference between left and right hubs. That's normally how I double check that I didn't over torque my wheel bearings/seals on my semi truck. Stethoscopes work pretty good too. On my pick up truck both front wheel bearing went out about the same time so if you find out it is a bearing...it might be a good idea to replace both sides at the same time. Good luck.

It does, but its only slightly noticable...

I do have a harbor freight stethescope I bought a while back for God knows what reason. What exactly should I listen for? Thanks guys.

pull the wheel off and check the brakes,
if roor and pads all look good
just replace the bearing, they are cheap enought.

if money is tight and time isn't swap the front wheel bearings

after you get the rotor and caliper off
its only three 15mm bolts holding it in the knuckle.

With the front jacked up put the stethoscope somewhere on or right next to hub and spin the wheel......then go to the other wheel and do the same thing. If one wheel sounds or spins notably different then more then likely one of your bearings is going bad. They normally make a more pronounced ticking sound if they are getting bad. If the bearings are real bad sometimes you can feel it being notchy or the wheel will stop on the bad spot when you spin it. Having said all that...sometimes you can't tell until you just replace them. As mentioned above they are very easy to replace.

Thanks everyone. Going to tinker a bit more, I have a feeling I'm going to just replace both.

You can jack up the front end and grab the wheel and move it around and see if its the bearing. thats how i knew i needed a new wheel bearing..it was wobbly

dano91

Yep, tried that as well. They are solid, no wobble.

Geez, I was 90% sure that everyone would hear the rattling or whatever that is in the video and confirm it is bad. I guess not....

I just wanted to get some more advice here if i could...I ended up just replacing both front wheel bearings last weekend and the noise persists. I took it to a local mechanic and he took it for a spin and could hear the noise in the front but said he doesnt believe there is a problem with the front bearings at all (they are brand new after all). He thinks the noise is coming from the rear bearings and travelling down the drive train/bouncing around the inside of the car and sounds like the front. I do recall last fall seeing oil on the rear wheels wondering where the heck it came from. Bad seals? There is definately a roar coming from the rear, but I though I would start at the front and try to rid that "noise" first, but it turns out there may be no noise.

He wants 400 to do the rear bearings. Im thinking about attempting to do the rears myself but here are my questions:

1.) What do you think about what the mechanic said?

2.) could there be anything else in the front making a noise? Brakes or tires?

3.) How can I trouble shoot rear bearing noise vs. gear noise or differential noise. I'd hate to tear all that apart and be wrong again!

Thanks!

Worn axles can cause leaks through seals and howl like dog!

- Pull axles check for wear
- Replace bearings when you re-install.

Grinding noise when applying the brakes is usually the worn pads....
Check rotors for lips (inside is deeper then edge) or scoring (grooves)....

Amazon has a great deal on AC delco rotors...$28.

28 bucks!? sign me up! Thanks!

fasteddy

Actually 26.72.... for the rears

Fronts are $34

dano91

Heres another update: Took it to a reputable shop and he said its 2 things -

1.) Bad bearing in the differential
2.) The noise from the front is actully from the TIRES!?

I am kind of shocked by this as its an awfully loud noise to be coming from the tires, I think.

He pulled it over and had me feel the tires and on the inside you can feel high and low spots. Would they be that loud? My next step is to swap front and rears to see if there is a difference.

I also talked to him about possible swapping the gear to a 3.73 while he's in there...I forgot to ask him - Can you keep the traction control if you swap out the gears. Someone told me you cannot, but I cant really find any verification of this.

I love this car, but it sure is a pain in the a$$. Thanks!

YES, tires will do that.
they can make tons of noise

NO, gears will have no effect on ASR

Awesome, thank you.

This may sound stupid, but does your center wheel cap have any play in it?
