Hi,
I posted some other threads regarding a bad hit on a curb i had to take on my Z06 to avoid a collision with a dolt that ran a red light.

Anyway i put 4 new wheels on it and had the old tires mounted and balanced. I then still had a pull to the right and then when i would correct it to the left it would make noises. It was a bad wheel bearing on the wheel that took the hit and i replaced it today. The noise is now gone but it still pulled to the right

I took it to get a 4 wheel computerized alignment at goodyear tonight (great price of 59 bucks) The entire suspension checked out perfect and the car was also brought into perfect alignment. In fact the wheel that took the hit needed the least amount of adjustment. Anyway i got it aligned

We took it for a drive and it still pulls right. Its not a lot but if i let go of the wheel within 5 seconds i am in the other lane. So we take it back and they say the only thing it can be is a radial pull from the tire and the fix is to reverse the tires so to speak.

The turn the tires around and rebalance and mount them and out we go again. STILL GET THE SAME EXACT PULL. At this point they give up and say it makes no sense other than maybe it just needs new tires and you can never tell with used ones.

I do not want to replace the tires. They are VGC pilot sports with only 6,000 miles on them. The pull is very slight and they insist the car is fine and has no structural damage. The only other thing they said is maybe a caliper is hanging up a little bit and its done that all along and i am just noticing it now (I dont think so)

What could this possible be. THey said just drive it and when the tires finally wear out (it will be 2 years LOL) the new tires should fix it. I am baffeled

Please advise

 

well just to share a story....

I bought a Matrix and it pulled as well...got the alignment...still pulled. Ended up being that the tire was flat, it had run flats. Maybe your tire is not keeping the air. I am not sure if your tires are run flats. Just sharing.

 

That cant be it. I just had the tires mounted and balanced again and we took the pressures, etc.

Something is going on, what could it be?

 

two things to look at The caster setting is it exactly the same side to side or merely within specs? the other is road crown if the road is crowned it will naturaly follow to the right the two things can compound to make it more noticible.

 

left the front and spin the front tires...see if they have the same friction? Does one grab more than the other. I can't see the curb causing the caliper damage though

 

did you replace both wheel bearings or just one side? maybe the new one has more/less resistance. Hanging caliper also possible. Bad calibration on the alignment equipment possible. Could just be the angle of the road.

 

I agree with this, but I think they would've checked that out if they say you're alignment is fine.

Other possiblities have been covered, such as tire psi, belts slippage in the tires themselves (I had this problem with runflats once), and the road crowning issue.

I say put her in the left lane on the highway and see if she doesn't pull left. Around here, my car always pulls left because I'm a left laner, where it dips down. If I shift to the right lane, the car will track straight or dip right. That's just how the road are around here it seems. Roads aren't often level, to prevent standing water.

 

pulls right regardless, wheels seems to spin fine when lifted. As i said it did not do this at all before the hit and now it does. Looking at the alignemnt sheet everything was fine tuned

I do need to replace the power brake booster in the car. the 01's are defective and i pull the pedal up with my foot after applying the brakes. Having said this i always have and it did not pull right.

 

Ok i think i found the problem,. I jacked the car up and both wheels spin pretty freely but the left wheel spins significant more freely then the right. I can hear a little of pad to rotor contact on both as they spin but the drivers side will spin about 50% longer with the same amount of force then the passenger side. Hence the pull to the right

Is this the power brake booster issue with my 2001 Z06. I have to pull the brake pedal back with my foot and have been meaning to replace it but jsut have not been motivated enough. I hope i don't need caiper too. My guess is the brake booster leak is causing the brake pedals to drag and even though i pull the pedal back its not the same as the pressure pusing everything back to normal. Why one side more than the other though. What do you think, think this is it??

Might be have you cleaned & greased the caliper pins?
if a brake is draging it will pull, if the master cylinder isn't retracted all the way the lines will still have some pressure and cause the brakes to drag. however. the brakes are setup diagonally so the left rear and right front would both have a bit of drag from this problem which should ofset the effect. I'd look at the caliper pins.

 

check the rotors for scoring..I'm havinfg a similar problem except to the left. Ihad the car realigned when I put new rears on. the fronts are now showing excessive wear on the insides of both fronts, more wear on the right side. My right side rotor has some scoring

 

If you smacked the curb hard enough to damage the wheel bearing, could the impact have transmitted through the rotor and affected the caliper? Either affected its alignment position vis-a-vis the rotor, or somehow damaged the caliper itself? Do you have a friend in the area with whom you could swap wheels for a test drive? That would potentially eliminate a wheel and/or tire problem if the car still pulled with the different rims. Good luck.

 

I had a pickup that had these same symptoms. Turned out to be a bad A-arm bushing,on the rack it would line up fine,
but on the road it pulled. You couldn't see a thing wrong under the truck. Don't know if this could apply to Vette's or not.
Hope you get it worked out.
