Re: The car is making a left turn by itself
My wifes windstar went in for warranty repair of squeaky tie rod ends, they replaced/realigned, we picked it up, and steering wheel was way off and it pulled a bit- they said "caster/camber split" was just a tiny bit off, but would need to move/weld upper strut mounts to 'fix' it...I said no way as it was fine before they touched it, took to another shop, and told them what happened, he checked it out, said not off far enough to hurt anything, and suggested switching tires left to right, as perhaps they swapped them during service- and it fixed the problem. The guy said it was 'ply steer', due to the way some tires are made they can tend to pull a bit, and also said alignment is usually off a tiny bit to allow for 'road crown', by switching tires, the problem kinda evened this out a bit, switching other way exaggerated it. I'd never heard of it, but thought I'd pass it along. (was bad enough to shift steering wheel 30-40 degrees off center)
I gave the guys at the Ford Dealership an earful, for wanting to drill/weld on an almost new vehicle- they use roadsalt here and it eats anything not galvanized...let alone the fact that when tires will be replaced I would have probably had to 'undo' the 'fix'.
As in prior post, if you havent had it aligned, do it- but will mention other minor things you've probably already checked: air pressure, draggy brake caliper, mismatched front tires(front drive tires must be replaced at same time or diameter difference can make it pull toward larger tire under throttle/smaller tire under braking), I'm sure theres a lot more that can affect it too. good luck!
