    On my 86 k5 305/700r4/np208 the power steering pump is leaking. I checked to see if it was a hose but it seems to be from the pump itself. The question is should i just go buy a new pump or can i rebuild the one i have. Anybody rebuilt yours? how hard was it?

    Thanks,

    Dustin

    is there anything involved in replacing it or is it as straight forward as take off old one and put on new one? Do i have to bleed the pump or anything? I know i need to replace the hoses while I'm doing it. How about the steering box, anything need to be done here?

    Thanks,

    Dustin

    I have never bled one and haven't had any problems. It's as eazy as it looks, just pull the lines and unbolt it and put the new one on. It's not a bad idea to replace the lines while your'e at it, but I'm cheeeeep so I never do untill I can see one leaking :rolleyes: I do however use air to blow all the old fluid that I can out of the steering box when I do it, don't know if it helps at all but it makes me feel better :p:

    I have replaced the seals and used that "stop leak" crap from Lucas oil. It still leaks. i have just decided that it does not leak nearl as bad as before, so i just live with it. I am going to replace it one day. I see no need to try and fix it any more.

    Yeah, the pump replacement is real easy. I would recommend getting the whole unit, maybe an upgrade to a high flow and a cooler if your up for it. Wont find an easier time than now.

    One problem you might find, is that most of the pumps you will buy do not have the pulley on them. You need to use your old one. You need a special puller for them (the crescent moon kind) to remove and install them. I got one from Lisle. They have them at most part stores for ~$30, or you can rent them from Autozone or something.

    Good luck...

    EDIT: To bleed the pump after installation, turn the wheel slowly lock to lock several times. That will purge any trapped air in there.

    I've used the stop leak stuff, and it worked on my PS pump.

    For the cost/effort, I think it's worth a try. It's not like you are out a ton of money if it doesn't work.

    FWIW, mine was leaking out the front, from behind the pulley. Not streaming, but everything was continually wet.

    I've tried the lucas oil stop leak stuff and it worked until i went muddin the next time then it started leakin again so i'm thinkin a replacement is in order.
    Where can i find info on a good high flow unit or would a stock replacement be fine
    Would a cooler be applicable for my situation? I only plan to run 35s because im running 1/2 ton stuff and front 60 isnt in the budget. If a cooler is applicable what would be involved in the cooler?

    PSC makes upgrades for our style vehicles. Many people use them with great results. Steve from ORD can get you a good price on them. A cooler is not necessary, just some cheap insurance that will probably make the pump and gear box last a bit longer. You can just use a cheap tranny cooler for them. I got one frorm imperial, the tube/fin design. But its up to you if u want the cooler, just more work and something to possibly break.

    If it leaks, let it be, after a while, it will stop by itself. Cant leak if it is dry ;)
