I have a 1982 GMC K1500. This junction where the steering column connects to this other part is moist and occasionally drips a reddish fluid. What is this other part called and what is involved in fixing this?

  • That's a leaking input shaft seal on your power steering gearbox. Usually replace with a rebuilt unit. – user9181 Apr 16 '20 at 17:22

If I understand your question correctly, I believe the part you are talking about is called a "rag joint". It softens the feel between the steering wheel and the steering box.

That isn't what's leaking, though. It appears (from the one photo) the problem is the seal from the steering shaft on the steering gear box. You could possibly replace it, but if time is considered money, you'd be better off replacing the entire steering gear.

  • Cool, thanks. I see from Moab's post below that the gear box is more expensive but I'd imagine significantly easier to install. – Dan Apr 16 '20 at 23:12

    I don't know about "easier", but I think a lot less time consuming. There are several parts which are tough to get off, so a bit of a trade off. Thing is, you have to remove quite a few of those same components to get to the seal as well. Thing is, after you've replaced the seal, you still have an old steering box which is most likely worn out ... which could be why the seal is worn out in the first place. – Pᴀᴜʟsᴛᴇʀ2 Apr 16 '20 at 23:25

That is a Power steering Gear input shaft seal, they make a kit just for that but is tricky to install, might be better off installing a reman PS Gear.

See kit Edelman 8525

See reman gear Cardone 277522

  • Thanks a lot! I appreciate the links. Is there a good writeup or book that would walk me through the process of doing this myself? I assume an alignment would probably be needed afterward? – Dan Apr 16 '20 at 23:10
  • Also, I'm told this truck has something called hydroboost where the power brakes run off of the PS pump. Will those reman pumps that you linked to be OK in light of this information or do I need a differnet one? – Dan Apr 16 '20 at 23:14
  • You will need a couple of somewhat specialty tool to replace the steering box. You will need tubing wrenches to remove the lines, a pitman arm puller to remove the steering arm that attaches to the steering box. a tierod breaking tool . You will also need a "large" breaker bar (pitman arm to steering box nut is torqued to about 180ftlbs). – mikes Apr 16 '20 at 23:25

    No alignment needed. "Will those reman pumps that you linked to be OK in light of this information or do I need a different one? " Gear box is the same for both. – Moab Apr 17 '20 at 1:13
