Find a smooth, quiet road and try rocking the steering wheel side to side at about 30 mph. If the noise changes it might be a wheel bearing, as they're alternately loaded and unloaded due to weight transfer side to side.
#6 of 14 Other suggestions to diagnose problem?

Okay thank you very much for the suggestion, but if the sound doesnt change when doing this then what might be some other things to consider given the nature of the symptom (roaring or humming w/slight vibration that escalates/increases as speed increases) 90k miles and the history/problems of the 97 LS Convertible model . Steering and suspension seem to be solid/tight and no problems at all with transmission shifting. The car is "tight" and rides very nicely otherwise i.e. accelerates very quickly (almost too fast) and is geared nicely.

Point taken. Sincere thanks.
#9 of 14 Took your advice re. smooth road steering test.
Nov 08, 2002 (5:11 am)
Found a very smooth low traffic road and rocked the steering wheel as suggested however the sound did not vary much, if at all. Decided that it wouldn't hurt to spend the $59.00 for a bearing/hub assy in case after removing the front wheels I find that(bearing)to be the problem. Senior tech at auto parts store said that with front end jacked up, should be able to grasp and wiggle the wheels one at a time to determine if there is slop, focusing on the hub/bearings. Noticed a substantial amount(more than usual) of (brake?) dust on front driver side rim. Humming sound seems predominate on that side. Sure hope this is it.

I don't think jacking the car on one side, grabbing the tire and wiggling it is a very precise indicator of a problem. How would you know what is acceptable "wiggle", or whether the play is coming from other steering or suspenion components? It's not good advice. You need to bust out the wheel bearing and examine it to know for certain or wait until things get so loud the problem is more easily detectable.
#11 of 14 you might be able to hear a brinelled bearing

aka one with a bunch of pits in it... by putting a mechanics stethoscope on the hub and spinning the tire. check with the others. if one sounds like a big wheel trike on a gravel drive, replace it.

I JUST FOUND THIS SITE - PRETTY COOL - ANYWAY - I HAVE A 1996 CAVALIER W/ 200K MILES - REALLY - I HAD BOTH FRONT WHEEL BEARINGS REPLACED 75K MILES. JUST FYI ....
#13 of 14 Oil Pressure on new truck
Dec 11, 2002 (9:27 am)
Have a 2002 Chevy truck with the 4.8 V8. The oil pressure stays around 60#. Dealer says this is normal but I was wondering what other owners
oil pressure was running. Thanks for any info.
#14 of 14 That's right -

should be 25-30 at idle, 60-80 on normal driving and acceleration.
