Power steering pump replacement questions

For those of you that have replaced your power steering pump...are there any special tools or procedures required? I plan to remove the wheel well liner and access from the side. I would like to purchase just the pump without the reservoir. Will I need anything to separate the pump from the reservoir, or any new seals or gaskets for putting the old reservoir back on the new pump? Also, will I need a puller to remove the pulley from the old pump, or will the new pump come with one? Other than these couple questions I believe it should be a pretty straight forward affair. Hopefully someone will let me know if otherwise. Thanks for the help!

For sure you need a pulley puller. The new ones are just the pump/pump w res.

IF you are replacing to help your steering(unless your pump has failed), it will not help.

As far as the reservoir, not sure about that but maybe someone else can chime in.

It's not so much my steering, as my braking that I hope it will help. It definitely seems to take more pressure on the pedal to come to a full stop than it used to. Also, when braking lightly there are spots that seem to grab more...almost a pulse, but not felt through the pedal. I did a visual inspection of the brakes and they seemed fine, however when I have a chance I plan to clean them up according to Heymcalls directions. My steering seems fine for the most part, but there are times when it takes a bit for the power steering to kick in. The combination of the braking and steering plus leaking power steering lines, are what was leading me to replace the pump and lines. If anyone has some better advice, I would love to hear it. Thanks!

Replace your leaking power steering lines. Especially the HP ones that always leak at the crimp. The pump to hydroboost line is the most common one to fail along with the line from steering gear to hydroboost.

Flush your power steering with a good synthetic like redline or amsoil. I would also recommend adding a cooler later on but you can then reevaluate the situation after you fix the lines and the fluid. Remember you loose pressure through those leaking crimps.

I don't know where to tell you to buy but I had to replace the pump on my '01 a few years ago due to a leaky reservoir. I purchased a rebuilt from Autozone and it worked but my steering was horrible after a while. I would have to fight the wheel at low speeds and this was with factory size tires. With the 20's I had, it was even worse. I ended up stumbling on to a used pump on Ebay from an '04 so I bought it and about 2 months ago, I installed it when I did the dreaded head gasket replacement. What a difference ! My truck now steers like new again if not better (its been along time since new). moral is be careful where you buy and I suggest to avoid cheap rebuilds.

You should be able to get a lifetime warranty with the complete thing. Pump and resivior.
I would also agree you want a powersteering pump puller/installer. Trying to get the pulley off anyother way usually results in a borken pulley. You can get it back on easy enough, but the puller will also do that too.

Other then that when you put it back on, jack it up, fill the pump, then with the key off turn the tires. The gear box will push fluid. So you can get if not all of the air out most of it before you ever start it.

I would also advise cleaning your brakes. (I did not read thru the entire thread mainly yours) However if it is the brakes you have a problem with and your steering is fine. It's probably just brakes. Granted when your steering goes your brakes do too. But if you only have a problem with one, start with that one.

You can search for this, but here is a basic run down. Take your brakes apart. Clean and grease the slide/caliper bolts. If they are real bad they are cheap enough to just replace. Also make sure your pads slide in the calipers. If they do not or do not slide easily you can file the notch in the pad that rides on the caliper. Just do a very small amount at one time. If you go to much, they can tilt and bind. Put them back together and drive it.
Also if your fluid is old and dirty it will have moisture in it, and can turn to steam in the lines if hot enough. Wouldn't hurt to flush your brake fluid too.
This is a pic of the fluid from the left front tire out of my 96. Buy a bottle of new fluid and it's clear if that gives you an idea of how dirty it is.

Got some what the same problem with my 04 2500HD. steering pump is starting to make a whining noise and the abs light comes on once in a blue moon & braking is different. The pump is gradually getting worse and the abs light as well. Plan on stopping by the parts house this afternoon and pickin a pump up and puttin my baby in the shop tonight. As for tools the pulley puller is a must imo and that should be about it to get the job done. Well I'll let you know how mine turns out.

Hey guys, I appreciate all of the responses. I didn't really put two and two together, but I have had the ABS light come up a couple of times in the past three months or so as well. I think I'll clean up the brakes and replace the power steering lines for sure. Might see if that does the trick before I replace the pump. On the other hand it would be nice to do everything at once while I had the wheel well liner torn out....

Up to you. Personally if you can do it inside and will be able to later, I would wait on the pump. You will get more old dirty fluid out if it dosen't fix it. Just me though, and for the time being it's less money to spend if it's not your problem.
I have a question for both of you though.
When your abs light came on, or after I should say, have you had any problems with the abs?
Mine has been on for a couple months. Haven't done anything yet cause it was praked most of the time and brakes including abs still work fine. But my abs is on constant. Spun my tires in a little mud and now I have an abs light. I am figuring it's probably just dirty sensors. Just haven't had the time, place, or time to have the truck down.

I have never noticed any problems with my ABS. My light has come on twice, both times were on start up and both times were after having driven on really wet sloppy roads. They occurred about a month apart from each other. I cleaned the grounding connection located on the frame rail below the drivers side door and I have not had a recurrence...that again was about a month ago. It is hard to tell if that was really the problem though as it was such a random thing. Both times it went away by shutting the truck off and restarting. If you haven't already, it's pretty easy to clean that ground and at least eliminate that possibility.
