I had this same issue when I took it to the first alignment shop i chose. no matter what they said they did it still had a significant drift to the right(they ended up blaming it on my lca bushings, which were fine). the second alignment shop I took it to said that the first shop had it so far out it was ridiculous. Even after getting it all in the green, they were still having issues with the drift to the right. In the end the fix was backing off the caster a bit on the left side and it fixed it. You definetly have something a bit out because I have the same tire size and my T drives straight as an arrow now.It's gradual, but if I travel on a road that is sloping to the left, it will track straight. Do u think its worth adjusting or should I leave it. Also, could the fact that I have 35x12.5 tires be a factor?
