A year and a half ago I had everything in the power steering system was replaced. Rack, Tie Rods, Pump, and all the hoses and lines. The pump was a rebuilt NAPA unit. I had a shop do all the work. Since I got the car back, occasionally I will loose all or some power assist. This usually happens when I'm parking or anytime I have the wheel at lock. My car gets parked on a super busy street that I have to parallel park on and that's where I get most of my issues.

 

Last summer I rebled the system and I although I got a ton of air bubbles I still had issues. It does seem like its not as bad as before. I rebled the system last night turning the wheel 50 or so times. When I went to start the car the pump was very very whiney (this pump has always been loud :bash:) almost to the point where it seemed like it was oil starved? Tonight I went to parallel park and again I lost assist.

 

So onto my question, does it sound like maybe my pump is bad?

Ya I'm pretty sure there is a lifetime warranty. I don't want to go through the trouble of replacing it just to find out it wasn't the issue.

 

Do aftermarket pumps tend to be loud?

I don't know. if you have a whine, try to isolate it to the pump for sure; you might pop the serp belt off and check all the pulleys. and if it IS warrentied.... get it replaced.

I need to check all the pulleys for an unrelated issue but I'm 100% sure its the pump that's whining.

remove belt and check for noisy, stiff or loose pulleys.

No I know how to check pulleys but I know for sure the whining is coming from the PS pump.

I had a advance auto reman pump on my bonneville give me all sorts of crap, whining seemed like it had less power at slower speeds, replaced it with a used OEM pump and that was the end of my problems.

I don't know if I want to mess with a used pump. But if I do put one on the plus side is I don't have to transfer the pulley.
