Bearing? or something else?
My car is making a humming sound when going at high speeds, 60 to 80 Mph and when going slow.. when pressing the brakes for a stop or red light I can ear a kind of grinding sound, but very light not a BIG grinding sound. (brakes are ok)
I heard a ticking sound when stopping also, but maybe maybe once or twice.. thats it.
I'm thinking one of my bearings is going bad, but witch one?

I just changed two front bearings on a 2000 Cavalier last weekend,
Are the rear berings on a Vette similar in setup? what about he front?
Thanks!

I left my Cavalier service manual in my other pants.
If you are referring to wheel bearings, the C4 front and rear bearings are of a similar type to each other. Not the same part numbers, but both, bolt on, sealed, assemblies.
By the source of the noise??? Looseness???
RACE ON!!!
and is there a difference between the front and rear berings?
What is the best way to determine what bering needs to be changed?
RACE ON!!!

Check your tires before going into bearings. They are pricy bastards.

I'm happy you brought that up, I didn't think about the tires. I had all 4 of them balanced last year and remember being told one of the wheels was a bit crooked... maybe that could be it, it was making a similar sound last year as well, but I've only really paid attention to it this year.
I know the wheel bearings are expensive, 280$ Canadian (that's with a garage shop discount) and me installing it. This is why I'm asking my buddy's on the forum first.
I really just want to know if any one had a good technique or trick to finding out what bearing is causing the sound. Last time I changed a wheel bearing on the Cavalier the only way I could tell it was bad was by turning it by hand, once it was all dismantled from the car. It was "barely" making any sound. When going 70 Mph it was a different story.

If one of your tires is showing bared cord, then it's a tire.
I am trying to remember... and can't, the proper testing procedure for a wheel bearing. In the front, it's easy, just jack up a wheel and wiggle.
In the rear, one way tests the u-joint, the other, the bearing.

The rear U joint were changed with new ones last summer or the summer before and they were greased since they weren't sealed U joint, they should still be good.
So? this is why I'm assuming Bearing, but if one of my wheel is crooked it would make sence that could be it also.

On the price of the bearings, I remember someone posting (it was a year or so ago) that you can use a Camaro or Firebird bearing (same GM part number) but much less expensive. Sorry that its not much help but maybe someone else knows if this is true.

As for tires, cord showing is a good indicator, but tire age and or wear can also cause noise like this. If the tires are seriously cupped, for sure.
