Re: Replacing a power steering pump on a 4.7L

Yep! Amsoil is working good for me now. Actually its in my engine, transmission, and power steering. Differentials are next.

Re: Replacing a power steering pump on a 4.7L

Well Aaron I guess I can't wait anymore. I think it's starting to affect my fan now. Temp is going up on hills ever so slightly. Never moved before not to mention I have about zero power steering sitting still. Time to get er done this weekend I guess. Thanks for the thread buddy. I'm sure I'll be referring to it this weekend.

Re: Replacing a power steering pump on a 4.7L

no problems getting that hi pressure line off?? I can barly get my wrench on at the top, but either end i cant budge, even after alot of pb and tapping... last thing i want todo is cut it..

edit: I got the fan end off and just pulled it and the pump together... yea what a bitch.. I removed the oil filter and wiggled the pump up in that way. The new fittings are bigger and better, my flank wrench doesn't even fit in the tight space at the pump I hope I can get it tight enough with an adjustable ;\

ps I didn't even remove the air box, it seemed more of a pain then what its worth..

Re: Replacing a power steering pump on a 4.7L

It is a b!tch to get the pressure line off the pump because of the tight space, but if you get the right size wrench on it and get it just right you can force it off, at least that was my experience. If you are replacing the hose I was able to get the fan end off no problem, more room to work down there. Yours must be corroded good.

Good luck this weekend Dave!

Re: Replacing a power steering pump on a 4.7L

Am I glad that's over with! bitch of a time getting it started down there on the fan.. scared to cross thread. The new hose has more of an arch to it.. before I put it in I matched them up and were way off, I didn't think it was going to work.

I ran it for 5 seconds shut it off, ran it for another 10 shut it off.. topping off in between, letting the bubbles settle... used almost 3/4 qt to fill it back up.

here are some pics of new and old

Re: Replacing a power steering pump on a 4.7L

Same experience here, the new hose was a tighter fit with a slightly different bend to it.

And yes, this system holds a lot of fluid, I'm glad I had 2 16 oz. bottles.

Re: Replacing a power steering pump on a 4.7L

When things turn ugly



After constant badgering by Aaron I decided to tackle this project in hopes he would leave me alone. That was my first mistake Friday after work I decided to finally start this project. After looking at the new parts I found out they gave me the wrong pulley two months ago.Check your parts if you're gonna let them sit a while. No problem got the right one when I took the core back. First issue I had was with that friggin high pressure line. Be prepared guys the fitting that might break loose is the pressure fitting on the pump itself not the hose fitting. If this happens you're screwed. There is no way to get to that bottom nut the way it sits so you have to go to the fitting on the bottom of the fan motor(Thanks for the tip hamilton5)

Make sure the o ring comes out with the fitting.



Whole deal out at once.



What a mess.



With the pulley and reservoir on there is no way to get at that bottom fitting so you have to pull the res. Just bend up the lock tabs and slide the clips off. Also if you get a pump without a res you have to do this.



With the res off you can just unscrew the whole hose and fitting assy out of the pump and break the 2 loose in a vise.





Hose was starting to get a little rusty.



Sanded and painted.



Clip where pressure hose turns down to fan motor.



Also this is THE setup for the high pressure hose. ratchet,6" extension and a 21 mm crows foot.



All back together and I actually have power steering again
I have to say though pressing that new pulley on the new pump sucked especially the last 1/8" or so. Definitely a two person job. Don't be tempted to use a press though you'll ruin the pump. Use the tool that comes with the pump.





Thanks Aaron for your invaluable instructions and misery you created for me and the nice buzz

Re: Replacing a power steering pump on a 4.7L

Found this thread when looking for some info. Saw the need to join to ask a question.

I've replaced the pump on my '04 Overland with a reman from Oreilys and the hose from them also. I used the Valvoline equivalent of the Mopar fluid. After turning the wheel back and forth many times my pump is quiet at idle but when running the RPM's up it's still squealing.

Any thoughts?

For the record I did put in some wrong type fluid before replacing the parts but never drove it afterwards. Is it possible the residual wrong fluid is causing this?

Re: Replacing a power steering pump on a 4.7L

Its possible, you could try unhooking a return hose to drain the old fluid, but my reman pump from Advance squeals on occasion too, it quieted down a bit after breaking in, but the power assist is great so I've just chalked it up to a mediocre reman.
