    Hey gang just sprung a leak on my steering box right were the steering shaft connects to the box shaft. So it looks like there is a seal there for the splined shaft that pokes out of the steering box.
    Is this leak a sign of internal failure or just a worn out seal?
    Should I even attempt to correct the leak or just get a new box?
    Allot of fluid has leaked out, well enough to drip down onto the spring pack and cover the bottom of the steering box with fluid.
    Seams kinda weird for it to all of a suddin spring a leak like this, so I'm thinking it has to do with the pressure side of the box and if thats the case I will just replace the unit.

    What is a top quality replacement for our rigs w/power steering??
    Thanks

    Whats up stranger????

    On the serious, I'd look into replacing the seal. I've heard that you can re-seal the whole deal for real cheap. I know searching the forums is a pain but I remember some good stuff a while back.

    Autozone has the seals. It's not real hard and I figured out a way to replace the seal without opening the box.
    The bottom seals you can remove the C-Clip and go full left crank and they will blow out...pretty messy but it works. Those you can do without removing the box. Leave the arm on to catch the seals so you can see the order they go in.
    The input shaft is a little more tricky. What I did is drilled two holes 180degs of each other in the edge of the seal so I could collapse it and fished it out with a awl and a cotter pin extractor. BE VERY carefull when drilling the seal that you don't knick the shaft or the housing. Make sure none of the shavings from drilling get in the box. I turned the box at an angle so the shavings fell away then took some brake cleaner and hosed out the end to make sure it was clean.
    Total in parts was like $14 with tax for all the outer seals. A Lot cheaper than a box for sure.
    Couple hour job at most...just messy.

    It's not my damn planet monkey boy!

    I had the same deal on mine (after it sat for a while) and the leak was pretty nasty. I removed the box (easiest way I think) and noticed the flange where the rag joint attached to was pretty crusty (1980 and in the snow belt). I bought a new flange from GM (don't remember the price), and a new seal ($6-8 from GM). The hard part is removing the top locking collar/ring. I clamped the box in a big shop vice, made sure the p/s ports were blocked and wire wheeled (on the end of a drill) the ever living daylights out of the top where the collar is to remove the rust/grime. I sprayed it with PB rustbuster and let it sit. I then took a big pair of channel locks and unturned the ring. Once that was done, I replaced the seal, cleaned the shaft and splines and reinstalled the lock ring/collar. Reassembled with new flange and rag joint and away I went. That was about 2 yrs ago and have had no problems. I do want to replace the rag-joint and shaft with a borgeson or flaming river steering shaft someday, but that is when I have the spare $$$$$...........which will probably when I'm too old to enjoy it.

    If you didn't built it yourself, how can you call it yours.......?

    Have you tried the power steering stop leak stuff yet? It sometimes works and is worth a try. It is cheeper than seals and alot easer. It softens up the seals and causes them to swell stoping the leak (sometimes). Try the recomended amount first and if that doesn't work than put more in.
