One of your brakes could be hanging up just a little bit… this would also cause the car to wander… If it’s pulling to the right, its gonna be a right side caliper that is hanging up on you…
I’ve been told that off-caster can cause a pull to one side as well… but with my suspension knowledge this makes no sense to me if your going in a straight line…
Start with tire pressure… then check to see if yur brakes are hanging up… this you can check by taking a casual stroll around the neighborhood… come home, and put yur hand near the rotors… if one is a whole lot hotter then the rest, thats yur culpurit.
