theres a bearing that the coil sits on, on the strut assembly. they get dirt in it and get worn out. does your car pull ONLY to the right? test this out, at a complete stop. turn the wheel all the way to the left ( probably dosent need to be all the way), then straighten it AS YOU accelerate. after that, if it feels like its not pulling as hard to the right, or is even going straight, the bearing im talking about is bad (not sure of the name)
