Tight/hard steering and won’t return to center
New to the forum. Recently purchased a 95 Wrangler. Noticed that the steering is tough and won’t return to center. No noise coming from PS pump. Checked fluid and appears good. Also, checked the ball joints to see if they needed to be greased. They appear to be ok. It is a bit rusty underneath everywhere, but it’s mostly surface rust. Car was sitting in their lot for 8 or 9 months before we purchased.
Any thoughts on where we should go from here? Is it possible the PS is bad or something else going on? Could the fluid be bad from sitting for so long? Or maybe a clog in the line?
