My 89 mustang gt used to drive like crap, so i changed the rack & pinion and the power steering pump and it still drives like crap. When i hit a bump it jerks me around. It doesn't do that so bad now with the new rack. Also, the steering wheel has a lot of play in it. Basically, it seems like I am all over the road. Could this maybe be in my head because i have a 98 cobra that drives perfectly, and that is what i am used to? Thanks to anyone who helps. I am angry that i spent about $200 on a new rack, pump, and hoses for nothing.
