Power Steering Pump

[njjeep]

i think my powersteering pump is starting to go out. it sounds like it is grinding sometimes and when i hit the brakes. which one should i get rockauto has ones some with and without resevoirs and some with and without "aftermarket filtration improvement" the brand they have are acdelco, a-1 cardone and atsco

my fluid level is correct but i have yet to flush the system do you think this would fix my problem instead of buying a new one?

thanks

I'd flush it and see if it helps. I'm gonna do a flush with Mobil 1 ATF. These PS pumps use ATF NOT not NoT NOT power steering fluid. Also you can stick a filter in line there too.

I have a brand new PSC pump kit that im selling if you would like but I would also try to flush it before you go out and buy a new one. My mistake thats why I have this PSC pump that im selling.

Little confused...why do you pump the brakes at the same time that you move the steering wheel from bump stop to bump stop? What does pumping the brakes do?

We don't have a vacuum all the time in these trucks (there is one between the intake and compressor UNTIL you let off the gas, then the boost goes out that way). So since the vacuum is small and unreliable, you need a way to run the brake booster. So you use the PS pump to boost the brakes. I'm guessing that there is a cylinder in there that is pushed by PS fluid and pushes brake fluid. By pushing it in and out you get the fluid left in there out and new in. I'm sure there's not much though.
