Noisy power steering pump? Possible quick fix.

Hey everyone, just as an fyi. My GC had a really noisy ps pump. Whined all the time, hissed, etc. It worked correctly, just loudly.

I flushed the fluid out yesterday, and Omg! It was the nastiest burnt brown crap I've ever seen. I have to assume that the previous owner took it to Jiffy Loooob, or the like, and that they used ATF to refill the PS reservoir. Once I replaced the fluid with mopar standard stuff, the pump was completely quiet again.


Hope this helps someone..

To flush the system did you just pull the hose off of the reservoir return and crank the motor? I've used that method in another vehicle but not the ZJ yet. I have some extra PS fluid in a sealed bottle on the shelf. Do Jeeps just take standard PS fluid or is it mineral oil like VWs/Audis?

I used a suctioning device to empty mine and added Lucas Power Steering and no more leaks( I used to have leaks too) and quiet.

Lol, I used a roll of paper towels. Just stuffed them into the res, soaked up the fluid, repeat until it's empty. Fill with mopar, run for a while, repeat.

Unless the pump is bad you should not have to replace it. Don't use paper towel rolls to soak up the fluid in the res, that is idiotic. Just use a large turkey baster and suck out the old fluid. If you want 100% of the old fluid out then pull the feed hose and aim it into a bucket then start the Jeep while you pour fresh fluid into the res. All of the old fluid will get pumped out and when it runs clear with new fluid then shut it off, put hose back, and top it off.
You can also use the turkey baster to do this over several fluid changes.

Power steering and ATF are just about the same. Just different colors. They are both hydraulic fluids but ATF probably has more additives in it to help protect the transmission.

I'm using Mobil 1 synthetic ATF in my Audi's power steering right now. Noticeably smoother turning. Some people here on the forum use ATF in their power steering as well.


By the way, you probably won't get an answer to your question because this thread is 8 years old.

Eventually the pumps wear and need to be replaced; the Mopar reman pumps are good and only about $100 or so; you need a pulley puller to swap the pulley from the old one on your new one. You can use ATF4 in the which is a synthetic fluid...
