Quick question about wheel bearings/hubs

Greg T · #1 (**permalink**) 09-19-2011, 10:07 PM

I have an 06 Envoy with 57000 miles. LOUD humming vibe from front end. Get noticable worse when turning the wheels slightly right and much quieter when turning left. Does anyone know for sure which one it is? I'm guessing LEFT side because of the added stress on a right turn, but don't want to tear the wrong one out. Ideas?

My suggestion would be to jack up the front end and place on stands, with someone helping you, have them put it in gear and let the tire rotate while you listen to each side. You may have to have them give it a little gas to turn them faster. The side the noise is coming from should be distinctive. I have had the same issue with my wifes car and it seems that you really can't tell which side it is by which direction you turn. Just my .02 cents worth.

That wouldn't work. It's all wheel drive and the noise is in the front. Would have to get all 4 off the ground. Thanx for the input, though.

I have an 05 Uplander AWD, probably the same bearings....I have replaced all 4......

I also work at a NAPA store....Wheel bearings just fly out of here.......Why cant these car companies still use repackable bearings?

If you jack it up, usually the noisy bearing will have some play in it if you wiggle the wheel. It usually is not hard to determine which wheel the noise is coming from while driving. make you you drive with the windows up, it is easier to tell.

I trusted my years of experience and pulled the left side. Sure'nuff, felt dry when I turned it slowly. o play tho. Tight as a new one, but you could feel the rollers. Got one from Rockauto.com for 64 bux shipped. All is good!
