The steering on my new 91+ has......issues. When I turn left, it kinda hesitates, clunks, then jumps over to the left, leaving the wheel off center to the left when turning back straight. It does it when turning right which then leaves the wheel off center to the right. The clunk can be felt through the steering wheel and column itself. And it feels vague, with a lot of pushback. When I got the car the PS fluid smelled rotten and felt gritty. It was almost empty and started growling so I threw some regular PS fluid from a gas station (i was traveling) in there and it quoted down and somewhat helped the feel. I'm pretty sure the tierod Sens are busted (i have new ones sitting here) and the rack is leaking. What else should I look at? Could the shaft going down have something wrong?
