Re: Please give me good news
Yeah, I've never seen a wheel bearing bad enough to cause a shake either. Only way I could tell other than the noise was by feel when turning it by had with the wheel off. Sometimes it's impossible to figure out which side is bad from the sound alone. That's why you have to feel.
my wheel bearing caused a shake. didn't make MUCH noise, but cause annoying vibration. went to autozone, got the cheapy $50 one and it went away. now when I replaced the pads on the driver side the bearing was grinding, so itll be replaced soon enough. only takes 15min. lol
Guess ill buy 2 new front tires and see where that gets me, i'm transferred 3.5 hours from home for work for the next 4 weeks making the drive back home for the weekends. I need this shake gone before something bad happens while I'm out of town.. Is it strange that it's been to two different shops( Cadillac and Firestone) and no one has said "hey your wheel bearing is bad" or something along those lines? I paid cadillac over 200 dollars to "diagnose" the issue and they came up with bent wheels, and they also did a full vehicle inspection and mentioned nothing to me other than the front wheels being bent.
9 times out of 10, you will hear a wheel bearing/hub assembly going south and if bad enough, poor fuel economy. It'll buzz/whirr as you're driving.
I still say tires, but instead of paying for a new set, do you have any warranty left on the ones you have on currently (the Michelin's). Michelin is pretty good about warranty and if anything you could get some pro-ration.
Something to concider....
Wheels don't just bend on their own. If you had a bent wheel or even concern of a bent wheel (i.e. dealer told you it's bent) think of this. If there was an impact hard enough to bend your wheel, chances are it damaged the tire that was on the wheel as well. If all your bushings look good I would certainly go with buying a new set of front tires or as stated above, try to get a warranty replacement on your tires.
The thing is I never did anything to the car to bend the wheels, I'm not sure if I just hit a pot hole or something, would the wheel being bent cause uneven wear causing a shake or would it have to be bending the wheel caused a warped tire?
well coming from a technicians view at a gm dealer you def need to do as boomys10 said and need to take wheels and tires to dealership or place that can roadforce tires, i have had ton of vibration issues that you can balance the tire all day and as soon as you roadforce tires you will find your problem. high spots in the tire need to be matched to low spot in wheel or either tires replaced if forcematching isn't able to be performed which the machine will tell you. def would recomend having that done tire with excessive runout will cause all kinds of vibration issues.
okay guys, after the initial bent front wheels the shake continued after I took it to Firestone for the dismount/mount, balance and, alignment it continued to shake.. I took it to the dealership again and to my surprise Firestone left off half the required weights.. The car is now running smooth as ever, thanks everyone for your input. I'm now selling it due to my need for a truck, if there is anyone interested in a 06 V hit me up
