I had front damage to my Corvette after rear-ending another car. The damage was mostly on the right front. The air bags did NOT deploy. The bumper, impact bar (UHS), right headlight and right front panel were all replaced. I was told the damage was essentially cosmetic and did not affect the frame/rails. After the repairs, I noticed a pull to the right. It was assumed an alignment would resolve everything.
My 2008 Z51 pulls to the right regardless of how the alignment is set. Initially, I thought this was a road crown issue but no matter how the alignment is set is still pulls to the right . The pull is slight but always there. I’ve now had it aligned at 4 separate shops, some 7 times. They all say the same thing. “There is nothing wrong with the suspension or anything they can see.” They all have said it can be adjusted but they all have failed. I have had Left Caster 7.7 and Right Caster 7.5 all the way to Left Caster 7.5 and Right Caster at 8.5. Obviously, the other alignment parameters were set accordingly, but no matter what the settings are, the car pulls the same.
One would think the tires at that point, but I’ve had three different set of tires on it not to mention I even tried different wheels. I then bought new Michelin Pilot Sport PS2, top of the line tires, and even swapped them side-to-side to verify any tires issues. Nothing changes the pull to the right.
I then had the frame laser measured. Nothing wrong with it and well within specifications.
Pretty much the suspension, tires & wheel, alignment and frame how been ruled out. To me that leaves Variable Effort System (VES), Electronic Brake Control Module (EBCM) and Antilock Brake System (ABS) that is acting as a outside force to make the car pull right. Unfortunately, I don’t understand how all these work.
I’m at a loss.....
