OK, I have avoided this question, but you make that hard to maintain......why are you bouncing from shop to shop? Looking for the one with the answer? Have the rest all given up on your problem? All I can figure is the pull is bad enough to make you pursue a cure.
I took the car in for the initial alignment because it was pulling to the left and the shop performed a 4 wheel alignment. The pulling was still there and the shop said there was nothing wrong with the car. Later, I had the car in a Toyota dealership for other work and asked them to recheck the alignment while they were servicing the car. The Toyota mechanic said there was nothing wrong with the car. ( It's starting to sound like me and not the car huh?) As a last ditch effort, I took the car to yet another shop which I have used in the past and they did another 4 wheel alignment and rotated the tires. Ok, so now I believe that the car alignment is set to factory specs as verified by 3 competent mechanics. But, at 55 mph, if I let go of the steering wheel, the car will do a fast lane change. I apologize for my persistance but I simply cannot believe that any car would be normal and pull to the left like this.
I have done some research on the Camry's and it seems that quite a few of them pull to the left. I would accept it as normal except for the fact that I have now stumbled across a Toyota TSB and Toyota acknowledges that the pull is not normal. For this reason, Toyota has issued TSB #ST002-04 and I am trying to get a copy of that TSB. Apparently, it addresses checking the alignment, rotating the tires and lastly adjusting the front spring perches. Obviously, I have taken care of the alignment and the rotation. According to the TSB, the last thing I need to do is rotate the spring perches but without the TSB, I do not know how much to rotate the perches.
