Don't know if this information will help but......back in 1985, I purchased a new Honda Prelude. I noticed early on that it would pull to the left. If I was cruising a three lane expressway in the center lane at 60, and I let go of the wheel, I would drift into the left lane pretty quick. So, I took it to the dealership, and had it aligned by a mechanic friend of mine. It still pulled to the left.....took it back again....aligned again......still pulling. Took it back the 3rd time......mechanic friend checked it again.....told me it was perfect. It stilll pulled.......and then I remembered something that an old alignment guy I knew told me a few years earlier. Radial tires can sometimes be a little "funny". One tire might not roll as easily as another. He had some cars he aligned that he knew were aligned perfectly. He switched the two front tires and the car drove perfect.....because one tire just didn't roll as easily. So............I jacked my Prelude up....switched the two front tires. This would reverse the rolling direction of each tire. It drove PERFECT! BETTER THAN PERFECT! Obviously, the left front tire didn't roll as easily as the front. By switching it to the other side, it reversed the rolling direction. I know that sounds a little unbelievable, but it's true. I also had another Honda years later that drove perfect.....until I put a new set of tires on it. I simply jacked it up.....switched the tires....and it drove as perfect as it had before. Anyway, that might be something worth checking. Hope that helps.
