ISS issues?

[992dr]

I have been hearing this random noise only when turning the wheel almost full lock (parking in lots, pulling out of the driveway) going very slow, never heard it before until recently.

Googling around found that the intermediate steering shaft was an issue for the GMT800 platform and also saw it for our platform as well. But, I have not seen any info for the SUVs, only Silverado.

Has anyone else experienced this or had to replace there intermediate shaft?

Thanks

Is it like a groaning noise and only lasts for a second? Mine does the same thing every now and then when pulling in or out of a parking space or driveway, but I don't know what it is.

Since I'm not the best at explaining or recreating noises, I'm going to try and get a video of it happening haha.

At first I thought what the International Space Station had anything to do with the Tahoe.

Anyway, I suspect I also have an issue with the ISS. I feel a clicking sensation while steering slowly. I already replaced pretty much everything from the steering box to the wheels a few years ago. Is ISS a mere annoyance or something that needs to be fixed?

The ISS is kind of a clunk feeling in your hands while turning at low speeds.

It is a mere annoyance, but can be remedied for about a year at a time by simply "exercising" it to redistribute the grease. I have done mine a couple of times.

I just disconnect the ISS from the lower shaft (1 bolt) and push the ISS in and out (or up and down?) towards the steering wheel about 100 times. Be sure to secure the wheel with the seatbelts so it doesn't spin on you. Takes me about 15 minutes and lasts for 9-12 months.

I came across this youtube video and it looks good. It actually looks like quite an easy repair done his way. Whether you use a Dorman or ACDelco, I guess that's up to you. I usually use ACDelco Professional parts because I've not had good luck with Dorman.

How come I get some notifications but not all ?

I tried getting video but whenever I do, you can never hear it. Then it only seems to happen when taking a sharp right turn almost full lock to full lock. Like parking a parking lot.

Haha. I believe it is just an annoyance but I also think its the beginning point of a failure. Even though I've never seen or heard of any failing. I love the looks I get when turning haha, its so damn loud. I will say, it seems to only happen when turning right.

I'll have to give that try to remedy this issue. Do you repack it with grease?

I think I may have seen that video.
Have you done this yet?
I'll try what HiHoe suggested and see what happens.

I do not add any grease. I have seen guys who do. I also read that you need to be careful because the shaft is designed to collapse on frontal impact, so you if you jam it full of grease, you may catch a spear to the face in a collision. I'm sure the truth is somewhere in the middle.

I did this to my burb last year after I got it. Felt like the power steering pump was going out. Pump was fine but I did as described here and it turned out super smooth again. I did take a can of the aerosol red and tacky grease and sprayed some into the shaft. I took the boot off too and hosed that down too and 'distributed' as others have described. No issues and I can't imagine it would be a problem in a crash.

After replacing my ISS way back when (I really don't remember when but, it was a while ago) the noise is back, yay.

The noise happens when turning close to full lock and full lock.

I'm determined to get a video of this noise this week/weekend to figure out what the heck it is.

 

[992dr]

Been trying to get videos, lets just say I'm no Steven Spielberg or Martin Scorsese haha

I'm starting to think it might not have anything to do with my steering and may be a hub issue. I'll be taking my wheels off this weekend to see if there is any signs of wear. Kinda boggles my mind because I replaced them within the last two years.

Well, hope everyone has a Merry Christmas and a Happy New Year. I'll be freezing my d**k off trying to figure this out

Sorry you’ll be freezing trying to figure this out, I hate working in the cold. I did it all my life. So when you replaced the hubs, what brand did you go with?

No need to be sorry my friend, I've been doing it for a while myself. If I can just finish building my garage that would be helpful haha. Trial and error with that though, not being a carpenter and all haha.
I'm trying to find out which hubs I used, so I don't use them again haha.
Which ones would you recommend?

Timken. They’re recommended by everyone and seem to last forever.

Were you able to determine it was the intermediate drive shaft? I'm looking at replacing mine and wonder how involved it will be

I replaced it with a new GM part, and I believe it was an updated version. I don't have any more clunks in the steering, I have clunks from other parts of the suspension that I'm trying to figure out
Replacing it was not difficult to do. I'd try to remedy it like stated above before though. A little grease may go a long way.
Hope this helps, if you need any info don't hesitate to ask.

OK, I'm having the same issue it sounds like (1998 Yukon 2WD) I was about to do the intermedate steering shaft replacing (the shaft that runs from the steering column through the firewall) but after watching many YouTube videos I'm starting to rethink things a bit. If you notice a lot of people that replaced that shaft found the noise went away for a month or so it seems but then came back and then replaced the column steering shaft lower bearing that the intermediate shaft goes through at the top.

Iv'e looked at my steering shafts, rotated them, attempted to move them side to side etc. to look for any play. The only play I could find was in that top bearing in the steering column (top end of the intermediate shaft) It has quite a bit of side to side play. I'm going to replace that bearing, I'm just debating if I really need to replace the steering shafts too? Almost as and experiment to see if the steering shafts are wrongly getting the blame. I have'nt taken anything apart yet, so I will know more when I take it apart. Maybe with it disconnected I will see some play in the u-joints or the shaft. Then I'll order them and put things back in.

Has anyone that has done this repair found physical evidence that the shafts were to blame for abnormal play or only that the noise had quit for a time and then returned?

I also ran across this video showing some tips to make the job easier. He didn't have the time to video the whole procedure so he recomends you watch those other videos and then try using his tips to make it easier.
