Hello, folks!

So I got this 2001 S60 T5. I got this last spring with a really bad power steering leak. I was able to get the flex hose replaced with quite a bit of cursing of course. Took it for test drive and found that the steering will stiffen at low speed.

So I ordered a power steering pump from ebay but they sent me the wrong one, looks identical with my pump but it doesn't have the thread for my pressure line. I found after I already installed it.

I installed the old pump back and tried to bleed as much as I can. With the car on jacks, I can feel the steering stiffer on idle compared to when I stepped on the gas.

My question is; is it the pump or the rack? Thinking of getting another pump but I wanna hear from the experts first before I get one.

Thanks.
