- I purchased a brand new Jeep Grand Cherokee power steering pump off eBay and it seems to be a great upgrade for anyone running 35" tires or larger.

I love this upgrade. When I did mine, I had to go through 3 of them before I got one that didn't leak. Turning my tires is so much easier. I'm locked up front with 33s.
Yeah I’ve read about some guys having to try a few pumps before finding a good one. Glad your works great and doesn’t leak now!!
@@mittenmotorsports I've had it for a few years now. Happy I did the mod. I also did the 140amp alternator mod too. Though I dont have any extra lights on mine...yet lol
Nice! I will have to look into that mod. i Didn't think these had any charging issues. @@TexasRedneck
@@mittenmotorsports just more amps for more accessories
Hey brother make sure your power steering lines aren’t laying on your lower radiator hose, it makes a big difference , great video thanks
Good call, i will double check. Certainly wouldn't want even hotter fluid or a hole worn into the hose. Thanks.
The reservoirs DO NOT swap FYI. I bought the XJ and MJ pumps and tried it.
What do ya mean they don’t swap?
@@mittenmotorsports it's been so long I don't remember exactly. The reservoir shapes were different, and I believe the hole sizes in the pumps were dramatically different
@@doomsdaydiesel I think you might be confused? I did it in this video. I just swapped reservoirs and fittings. All is well with it.
@@mittenmotorsports it definitely doesn't work with all brands. You got lucky.
For the 1/2" hose coming off the bottom of the PS pump, did you cut that 6" section from the return line you link in the description?
No I did not. That was the new return line that I bought and then I bought another 1/2" piece of hose from advanced auto and used brass connector to connect the two different hoses.
You did use ATF +4 in that new pump I hope, and not off the shelf PSF. PSF has a totally different viscosity, among other things in it that Mopar steering pumps DO NOT like over the long term.
😂 I just used orielley PSF. Didn’t know that before hand. Where did you learn that ATF was better for the pump?
I've been involved in the automotive industry in one form or another since the mid 90's. A Tech for a long while, and in parts, and service. I believe Ford was the first to get away from the old Saginaw (I think?) type P/S pumps in the mid 70's when they started using there own proprietary P/S pumps. Ever wonder why you always hear the old Fox body Mustangs driving around with a wicked P/S squeal? Those pumps were designed to use Type F Ford P/S fluid. It had grit in it to help the vanes in the pump stay honed and true to the pump bore. When using regular P/S fluid in those pumps, the vanes will not stay honed to the bore and start to squeal like a stuck pig. Not too long after, Mopar changed to their own pumps as well. The first were to use ATF +1. So as the decades past by, changed to ATF +4. Chevy held on to the old style pumps, because no one else was using them. These companies no longer want parts compatibility between vehicles. They want proprietary part only to help their own after the vehicle sale parts business. Look in the service manual, and the owners manual. It will specifically say to use an ATF of some sort. I think that this is way a lot of folks have trouble with their P/S pumps. The old style P/S fluids are too thick, and do not have the proper additives for the pump bores and seals. Newer style pumps used to have a steel sleeved bore, most of which now no longer do. It usually is just the vanes against an aluminum bore, which scratches and wears out very quickly when not treated right. Where you put the adapter hose (1/2" piece), you could have used a P/S filter. You can get the filters with a 3/8" inlet, with a 1/2" outlet.
Wow you have some history in the industry. I have been considering adding a cooler to this setup so now I think I want to drain the system and add a cooler and filter with ATF+4. Does the ATF+4 help with aeration at all? Thank you for the lesson by the way.
@@mittenmotorsports Yes, absolutely. ATF's additive package includes anti-foaming agents which will greatly reduce the problem of aeration in the fluid, and premature failure of the pump and gear box. All these fluids, by the way, are just different versions of hydraulic fluid. However, not all hydro fluids are the same. It depends on the application. Most all P/S systems now are high pressure, and high temperature, where ATF's work very well in. The older P/S systems were lower pressure, and temp, where the old type P/S fluid was adequate.
To my knowledge, all WJ power steering pumps should be serviced using MS5931 fluid and not ATF+4. Oreilly brand PS fluid is compatible with MS5931, that is stated on the back of the bottle.
I'm am not sure what the XJ gear box calls for... but the WJ pump is definitely MS5931. This is stated in Technical Service Bulletin 19-005-03 which can be found with a quick Google search.
What year is your XJ because I’m doing this swap right now on my 88 and the pressure relief fitting that has to be swapped from the XJ pump to the WJ is not the same diameter and will not tighten down
This is a 1998. It’s possible the 88 fitting is different from the 98 fitting.

Went into NAPA today and looked at ones from 96 to 2000 and they were all the same. The only thing I can think of doing is getting a hydraulic hose shop custom built a pressure hose.
Can I get a Hell yeah...😁😁
Oh hell yeah
Would the high pressure hose from the wj work in the xj?
I am not sure
