I have a low growling type of noise while driving my 2002 Trail Blazer. The noise is not constant and seems to change on left hand turns and my ABS light came on. When I asked around, I was told that it may be a wheel bearing. With 107,000 miles on the truck is this normal and should I it? There are two wheel bearings, right? Should I replace both of them? How much do you think it will cost?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Kathy, Yes it is typical to have to replace wheel bearing around 100k miles, and yes, if one side is replaced the other side is recommended at the same time or (no more than a few months apart). In most cases you can take your vehicle to a local auto parts store an they can read your codes are reasons for the ABS light to be illuminated . Each wheel bearing average cost can be around $400 each.

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube It could be a gear box, tire, or wheel bearing - take it to a qualified mechanic

Laurie Sarno, Co-Owner at Super Girls Auto Most modern wheel bearings are of the sealed "cartridge" type. It is certainly not uncommon for them to fail by 100,000 miles. There is one bearing assembly for each front wheel, however the rear axle bearings are contained within the axle housing, and there are six altogether in the rear axle assembly on your particular vehicle, but these are internally lubricated and seldom fail. Your front wheel bearings cost anywhere from $75-$250 each depending on the source of the part (parts store or dealership), and installation for both sides is anywhere from $150-$350 or higher depending on the shop hourly rate. To save future problems, I would replace both, since one has failed, the other may soon follow. Hope this helps - Super Girls Auto

Suzanne Grego, Technician at City of Philadelphia Fleet Management Kathy, I would also suggest that the cause of the noise is a wheel bearing. This sound is normal when they go bad and this is a safety issue. If you like this vehicle and don't have many other concerns with it, then yes, I would repair it. Labor rates and parts prices vary from area to area. I suggest, first having the vehicle looked at by a technician that can say for absolute certainty that this is the problem. Then you can shop around a little. Call a few reputable shops and ask for the best price. Suzanne
