power steering pump?


Recommended Posts

the power steering in my 96 XJ feels ok except at idle.  at idle it feels like it's simply not there.  but if I give it even just a teensy bit of gas pedal, it instantly comes back.  failing pump?  I've bleed the thing repeatedly with no effect.  the fluid looks clean and doesn't foam.  and it doesn't sound all that bad. :dunno:   I know the previous owner had a leak that was addressed by just dumping more fluid in each week (I've since replaced the leaky hose).  dunno if it was ever run dry.

Mine does the exact same thing. Here's the real crazy part:

 

When I lifted my Jeep, I used my dads steering box and power steering pump that already had a drop pitman, and I gave him my power steering box (he took the lift off his XJ right as I put one on my MJ, it worked perfectly, actually). On his XJ, with my power steering pump and box, the power steering worked perfectly. With his pump and box on my Jeep, same issue.

 

Coincidence? Probably. But something doesn't make sense... :???:

sooooooo, that middle piece.  does it pop out or anything? :dunno:   I see nothing down the hole, nor can I get (if the bottom of the hole is indeed the top of the middle piece) anything to move.  Is this a procedure where I need to remove the pump and smash it vigorously on the pavement? 

 

also, car-part.com shows my pump interchanging with 97+ jeeps, if that means anything.

Yes, they are interchangable. You're right about the bracketry differences and there are other subtle differences, but they are all Saginaw TC pump variations. My old 91 original pump was tired and leaky, so when I swapped in the quick ratio steering box from a 98 ZJ, I also swapped in a newer pump from a wrecked 04 Wrangler TJ. The only difference was the departure angle of the reservoir return hose nipple, and it worked just fine with both the original bracketry and the newer 1997 and up bracketry I used for the new 01 intake manifold later.

As I had posted here before, all the pumps are interchangeable.

This is off a '04 Grand.......what is different is the bracketry and some pumps are threaded and others are not and are for through bolts....these can be threaded as this one is-

Thursday I picked up the correct bracket for the MPI intake that I will use on my new engine..........it's really cool how we can mix and match parts here from different years and from 4.0s to 2.5s

update:

 

changing out the pump cured it.  but I wasn't able to reuse either of my older pumps because both had rotted pulley-attaching threads and you cannot use the old pulley on a newer jeep.  it's close... close enough to work well enough for me to install one for a few seconds as a proof of concept, but it'll tear up the belt for sure.  so I got a new pump and all seems well again. :D

If this is true, is there a more powerful pump that we can swap over from a different year model?  for example like we can do for the 99 durango gearbox?

I run an 01-04 WJ pump through-bolted to the stock 87 Renix bracket. Had to use my old 87 pulley for everything to line up because the 01-04 pulley sits out 1/8" further. Pain in the behind because the old pulley does not have the bolt access holes. Had to install the pump first, then install the pulley on it.

 

I did run the new pulley for a couple of weeks trying to figure out why the belt was squeaking.
