Well fellas the sts v has got me gone in a loop! Here's the story: Recently my car has began to shake at speeds 65+. I took it to the dealer where they told me I have two bent front wheels... Quotes me 978 and some change A PIECE! And i was charged 298 for labor for them "finding the peoblem"So I said screw that and bought to NEW never used wheels online. For 340 a piece. Took them to Firestone auto care to get them mounted balanced and an alignment.. After all said and done I'm 700$ deep into this and guess what still shakes! Please help me !

Did you re use the original tires? Are they worn any way?

Have you inspected the struts and control arms for bushing wear? How many miles on the car?

All suspension has been listed, how about brakes. Are the front rotors experiencing some form of rotor runout that's bad enough to impact things even while not braking. Although I would think this would be a progressive issue at all speeds...

Tires can still be the culprit too. I can look at a tire too and tell you "it looks fine", but even a brand new tire, based on it's mold, can sometimes not be within tolerance enough to be offset by wheel weights and being balanced. Add in wear and overall usage and it can only exacerbate the issue.

oh oh oh let me let me!! just dealt with this. lol. I went in due to EXCESSIVE inner tire wear. found out the lower control arm BUSHINGS where bad, and had a ball joint pop (which I had known about for some time) so I jumped on ebay got a GREAT DEAL on lower controls arms had then in two days, had them installed and couldn't get alignment in spec and vibration still there. immediately I started thinking the tires I had bought were just junk (they were cheap ones to tide over until suspension was fixed). noticed the rotors had some hot spots so went ahead and ordered new rotors, replaced those and high speed vibration was still there. took it back AGAIN today for the third alignment process in 1month. finally got it in spec with straps and many ppl helping and the vibration is now gone. firestone ALSO did my alignment.

Was you car in an accident? That seems like a lot of suspension and subframe work (I.E. damage), to have to realign.

Who was the one who did the final correct alignment?

Boomy what specs did you set for front alignment??
Also PS on tires--sometimes the belts inside the tires can shift causing major vibrations--they will look fine,but be very bad--to me id feel it over 70

Your back wheels could be bent as well, happened to me already, couldn't figure it out until I bought new tires for the car and found one of my back wheels bent slightly. Replaced it and no more issues. The stock wheels are prone to warping like any other wheel. I would have them all checked. I also agree that your tires could be out of round to. A buddy of mine had that issue as well. Good luck!

back wheels or tires OR driveline issues will be felt in the floor/seat of the car not the steering wheel. steering wheel is usually connected to the front only. I will have to get a pic of the new alignment stuff. my car has 100k on it so im thinking maybe the springs are settling OR the shocks might be slightly bad to cause the issues we had alignment wise. its 100x better now. found out a back rim IS bent, but with the new tires is 100x better so I don't care currently. lol. also OP you might have bad wheel bearing, those can cause steering wheel shaking also. take wheel off and spin the hud, youll know quickly if its bad.

Thanks for all the posts fellas, the shake is felt in the front/ steering wheel also. It feels like it's right underneath me when I drive. Wouldn't an alignment be able to pinpoint the problem area?

An alignment is only going to tell you where the wheels are pointed. I've had alignments where the guy didn't notice that the tie rod was worn out. You can check for bad ball joints and tie rods yourself easily. Jack the car up and grab the wheel from the top and bottom and try to rock it. If it moves you have bad ball joints or bushings. Then grab it from the front and back and try to rock it that way. You'll be able to feel it if the tie rod is bad.

you can road force the wheels also to see if a rim is bent. since often you cant see if with eyes or by rubbing your hand over it. id find a shop local to you (from my understanding must firestones have roadforce machines) that has a roadforce balancer and have them balance all four tires. that will tell you if rim is bent. do what time said to find out if tie rod is bad, however, with the moving back and fourth it could also be a wheel bearing, so id take the wheels off and spin the hub with the lug nuts, if they make noise I would replace them as they should not. once all of that is done and everything is good, have it aligned again. once that is done take it back and make sure the alignment is good. I would almost guess that you have a bad wheel bearing though honestly, my passenger side was bad and didn't show any signs other than noise (which I could never hear) and caused a bad vibration.

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

Thanks everyone for the input so far... Do you guy's think based on my problems that my car is safe to drive?

I would be concerned its a bad cord in a tire and that can go a any time. If you are 99.5% shore it's not the tires you should be fine to drive it.

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.

We're these the tires that were on the bent wheels?

im currently driving on a slightly bent rear rim. just don't have time to deal with it currently, are there any long term issues with doing that mad?

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?

I think you hit some thing in our on the road some times it's the small holes that get you. And it bent the wheel and messed up the tires.

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 ;)
