I've had my 03 in a 3 times to try to Diag the pull to the right. Even took it to an independant who specializes in high end hard to align vehicles.
First; I'm told only one of 3 geometries in the fron end is adjustable. Other two are factory set, so alignment perse, is not adjustable.
The front end was just within normal tolerances the 1st measure, and seems to be migrating worse over time. Under close scrupulous investigation, there's no sign of previous impact damage or repairs. my cars got 45k miles.
The best recommendation was to check tires, or for brake drag. I had new tires / wheels, and a brake job done. No better.
I took it to the dealer for a 2nd look, no luck. Now a month and a half after the 1st alignment, I took it back to the first guy to look at again and the front end tolerances have migrated slightly worse.

???
Any body out there had similar alignment difficulties, found any HTF soltions?
Thx, David
