Strange Noise, Help!
I noticed this noise in the 98 on the way home from Carlisle. It is a low pitched buzz or hum that sounds like it is coming from the rear of the car. If I take the car out of gear it remains constant untill I coast down to about 30-35 mph. It then goes away and the same thing happens if driving under load. The noise disappears at under 30-35 mph. I'm wondering if it's a wheel bearing. Anyone have anything similiar to this?

Hmmm, not sure if my problem was exactlly like yours. Mine was a low pitch rumble, sort of hard to describe, like a rmmmm, rmmmm, rmmmm. It also did not change pitch when i changed from accelrate to decelerate, or take out of gear. My noise started at about 70 mph and got louder the faster I went. It turned out to be a rear wheel bearing.

Mine starts about 55 but from your description I'm leaning toward a rear wheel bearing.

Re: Strange Noise, Help! (XCELR8R)
Same situation with our 1998. 63,000 miles and the noise starts about 35 or so and continues. Thought it was tire noise and replaced the bald rear tires, but no change in noise at all.
Will go to the shop next week for extended warranty repairs.

Re: Strange Noise, Help! (jimhild)
Mine also was diagnosed as tire noise initially. Mine only has 20k miles. Luckily it was covered by GM warranty. I think the bearings are a sealed unit and are quite expensive. I never saw the price.
I noticed my noise after getting new Michelins, so that's why some thought it was the tires. I think the noise was there before the tire change. The old noisy Goodyears just covered the noise.

The car has 49,000+ miles on it. I haven't checked to see if there is a change in pitch during side loading. I'll try that today.

Re: Strange Noise, Help! (Mark 84ltblu)
I recently drove a '98 coupe with 51K miles on it and new Goodyear F1s, and it had this AWFUL noise coming from the rear of it over 35mph. Sounded like tire noise (definately not diff whine), but I know the F1s are not this loud. LMK if yours turned out to be a bearing, as I'm thinking this is what was wrong with the car I looked at. I'm curious to see how $$$ it is to fix. The one I looked at was a nice car, otherwise...

Re: Strange Noise, Help! (C5Luv'R)
I found a place on line that sells both Timken & Chicago Rawhide bearing assemblies. They both go for around $ 160 and I'll do the labor myself. The Delco bearings are $349 or higher and I bvelieve are made for Delco by these two companies.

Timken is the OEM on these bearings. Can you tell us where you found them as Autozone has been hit and miss. Also I have a 1.8 meg file that somebody put together that shows a step by step proceedure if you would like me to E_Mail it to you?
