I have a '95 YJ that I have found pulls fairly hard to the right going downhill (especially at higher speeds) and pulls to the left or simply stops pulling to the right when I start going uphill. I really discovered this yesterday driving on a road that had multiple little hills one right after another. I would find myself fighting the steering trying to pull me to the right going down the hill and then at the bottom as I started to go up either the pulling switches to the left or it simply stops but I haven't stop trying to correct which pulls me to the left. It's really annoying because I probably look like a drunk driver veering left and right as I go up and down. Any thoughts?
