Rolling Noise, "Mechanic" Says Bearing
|
Can't Post
|
|
Hello,
2002 "Olympic" model, manual transmission, low mileage
I had the front disc brakes replaced recently. Apparently, if the bolts are overtorqued (using an un-calibrated air wrench), some damage may occur.
My unlicensed mechanic changed the right wheel bearing, but I told him it was the other wheel making the rolling noise. He said he would change the other bearing on "3 or 4 months". I want to fix the problem now.
Is it really the bearing that makes the rolling noise? He didn't hear it during a half-mile test drive, but I hear it quite a lot. Mechanic says the tie rod ends and ball joints are all okay. He doesn't have any electronic equipment other than a wheel balance machine.
Could it be the universal (U) joint? What are the symptoms of one failing?
Thanks!

Depends on what exactly the "noise" sounds like and when you hear it.
Technically the PT only has CV joints (constant velocity joints) rather than U joints - same functionality but with much more flexibility and therefore less binding. Anyway, bad CV joints make a kind of a cracking noise especially when the wheel is fully turned. Go to an empty parking lot and with the wheel in full lock just drive in circles a few times. Then repeat in the opposite direction. Listen for the cracking noise which will tell you that you have bad CV joints
If the noise is a low-pitched "growning" noise and you hear it when you are driving, especially at moderate to high speeds, then it is likely to be a wheel bearing. When wheel bearings first start to go bad, you may only hear the noise when you turn in one direction but then it goes away when you go straight or turn in the opposite direction. If neglected, the noise will get progressively louder and will eventually become constant.
If the noise is a high-pitched, nails against the chalkboard kind of noise, it is likely to be the brakes.
Other components mentioned, such as tie rod ends, ball joints... don't make any kind of rolling noise that stays on for any duration. When they go bad the clank here or there as you hit bumps and/or turn the wheel but I would not describe their noise as "rolling noise."
It's kind of hard writing about noises without actually hearing them, but I hope this helps a little.

In the early '80's I was "School" trianed for suspension and brakes. They drilled into us, "What you do to one side you must do to the other." the reasoning was to maintain consistancy and balance in all the systems which will help prevent other problems further down the road.
Just go tell the guy you want the bearings replaced now. He would be a fool not to do it.
