Intermediate steering shaft troubleshooting

[Scasper1010]

Hello all,

So I’ve had the dreaded steering clunk in my 2005 Tahoe. I had a mechanic come check it out. Quoted me 550$ to replace the “upper steering”. After looking on the internet I see that this problem is somewhat common and is traced back to a problem with the intermediate steering shaft. So I got the requisite replacement and thought I could change it myself, after watching as many YouTube videos as I could. Here’s where I hit a snag, I could not for the life of me get the shaft to come out of the upper steering shaft or lower shaft. In every video it takes people a mere finger to push the ISS out of the upper shaft and I couldn’t get it to move a millimeter. Anyone have a similar experience? I really don’t want to pay someone a bunch of money to do something that seems so straight forward.

Thanks in advance, this forum is great

Yes sometimes they get over tightened! Mushroom the shaft. Vice grips and a hammer.

I all did was lube the shaft and the clunking went away.

Same. I didn't add grease, though. I just "exercised" it to redistribute. Has worked for me twice doing it roughly a year apart.

I tried a bit of this, but I don’t know how to get proper leverage.

Works great for about a year. If you do add grease, don't put too much. You're just filling the space that (as he even says in the video) is designed to be there so the shaft will collapse on impact. I haven't added any grease to mine, just push it in and out about 100 times.

If that doesn't solve it, your bearing at the top is probably shot. Only use AC Delco if you end up replacing that one. Problems reported with the Dorman one.

If I have to grease it again, I'm going to add the grease fitting like the video below.

That’s the problem, I can’t get it to collapse at all. If I could I would have popped the replacement one in yesterday, instead of screaming obscenities as I couldn’t move the thing a millimeter. Ughh might have to actually take this whole thing apart to get it out.
