Ok, so my wife's 95 ATX has been having some... issues. One day on the way home from work, her front left wheel fell off. We don't know whether somebody was trying to steal it and only got halfway through or what, but one of the studs was snapped and the other four were stripped pretty bad. There was major vibration beforehand, and fortunately she pulled over before it actually fell off, so no major damage was done. She was also right across the street from an AAP so she and a friend of mine hammered some new studs in and all was good. Or so we thought.

After that, the car started making a weird noise. It sounded, honest to God, like a swarm of locusts was following the car. I didn't know what to make of it, and my wife was adamant that it was the wheel bearing. It started getting a little louder, and the other day it started making a horrible screeching noise. I drove it, and it sounded like the pie tin was touching the rotor, and I told her so, but she was inconsolable. She wouldn't drive it. So one of her coworkers at advance auto called around and found a shop that would replace her wheel bearing for $160, provided we supply the parts (which we had). Pretty good deal.

We take the car into the shop. I tell the mechanic to check the pie tin cos it might be touching the rotor. He takes it in, we go back to the store. We get a call 20 minutes later saying it's fixed. Turns out it was indeed the pie tin touching the rotor (score one for me!). We drive it, locust sound is still there. Granted, it's hard to hear in traffic, but he didn't charge us anything to push the pie tin back so we weren't too worried. Everybody that knows him says "if he says it's not the wheel bearing, it ain't the wheel bearing."

One of her regular customers comes in who fixes people's cars a lot and Michelle (the wife) asks him if he can drive the car and see what's wrong with it. I go with him and we come to the conclusion that the ABS sensor is contacting the ring. It sounds plausible; the PRF is about right.

I have to go to work, but michelle comes home and checks the sensor out; it's not touching anything. So we're back at square one. It's not the wheel bearing, it's not the ABS sensor. What the **** is making this noise?

We put the front of the car up on jackstands and run the wheels so I can hear what's making the noise. It sounds like it's coming from the calipers. Could the slotted rotors be making this noise as the slots pass under the pads? They didn't make that noise when installed... but it's possible. I took a video of it, you guys be the judge. I also took a shot from above the wheel to see if it's wobbling at all; the wheel might have been thrown out of balance when it fell off as the hub landed on the inside of the wheel. You can see the freshly painted calipers and brackets that got all fu**ed up :madflame:.

Anybody have any inputs? I'm tired of telling my wife her wheel bearing's not going to self-destruct. I need some backup. You be the judge...

- Just guessing, but I would add a new suspect - CV joint. No guarantees, hard to tell by video sound only. Repeat this test and turn the steering wheel lock to lock. Listen for a difference in pitch or volume. It may announce itself more clearly.

If you get no leads from that, I would take off the wheel and look for indications of contact on the inside of the tire. If nothing shows, remove the caliper and check for something loose or trapped within. If nothing shows, hang the caliper out of the way and repeat the running test. Remember to NOT apply the brakes until the caliper is re-installed.

If nothing found, report back here.

Did the rotor/hub impact the ground when the wheel feel off.

I'm gonna say its still the wheel bearing. Balls are flat. Check around the bearing seal for signs of grease. It just sounds so much like a bearing with flat balls or no grease. If it is you will find out soon.

I had a car back in high school (yes we had high school back then) that had a wheel bearing let loose going down the freeway it's not pretty. It sheerd my wheel off via the lugs and then proceeded to inflict as much damage as possible to the front quarter panel.

I guess I should've mentioned... it comes from both sides. Equally loud. Also, I don't know if you can tell from the video or not, but the sound is loudest from the caliper area. I moved my whole head around the circumference of the wheel while it was moving and it was loudest by the calipers... but thank you for the tips. I will keep the new hub/bearing for now... and pray to the Parts Cars god should the worst happen. I hope she doesn't lose control if the wheel comes off!

Sound can eminate and transfer thru anything causing it to sound like it comes from all over.

But since there are marks on the brake caliper it wouldn't hurt to one like SASHO91 said remove the tire and see if it stops and then the brake cailper and see if it stops. Keep in mind when you pull rotational mass off the bearing such as the tire the sound may stop as well. So unless you can definatly find something then you may just be just givint the bearing a breather and reducing/eliminating the sound.

The bearing that I just recently replace would not make any noise unless I had the weight of the car on it plus turning a certian direction. Outside of that I only found play/roughness in the bearing once I had removed it from the spindle (Gen III so it just requires 3 bolts to remove).

- Just weighing in again on this. With the caliper hung out of the way, you should try the test with wheel on and with wheel off. When wheel is off, remember to re-install the lug nuts to ensure the rotor stays put.

So now it's on you. Jim Morrison said, "You can not petition the Lord with prayer". That may or may not be true with Parts Gods, but please minimize or eliminate travel in this vehicle until you have at least tried this simple, free, informative, diagnostic test series.
