Re: 97 Astro Van Steering Shaft Swap info
Maybe I'm missing something here (as I haven't looked at the one on my car yet), but are the splines on the steering box keyed so that the coupling will only fit on there one way? If so, then having to rotate the upper coupling 90* makes sense.

Re: 97 Astro Van Steering Shaft Swap info
I bought two units, one from each, a 97 Astro and one from a 02 Safari. From what I can see both of them are clocked the same. The Astro version actually has a larger (more material) upper joint. While on the safari version the upper/lower joints look identical, with exception to the Double D on the upper joint for mounting it to the steering column.
Secondly the Astro version seems to extend an extra 2 inches (or so) more than the Safari version. Im not certain any of this matters at all or if there would be any concerns about deflection at all with the longer steering shaft. (I doubt it would matter.)

Re: 97 Astro Van Steering Shaft Swap info
Ok here you go: All of the photos show the upper rag joint as the 02 GMC Safari unit and the bottom is the Astro.
This one shows the difference in size between the upper mounts (where the Double D is located)
This one shows the joints as short as they can go.
This one shows both joints to their full extension.
Note: both of these joints are in stock unmodified form. Both clocked in the same way.

A couple vids that may clear some questions up. Not the most direct to the point with info but it's helpful none the less.

Re: 97 Astro Van Steering Shaft Swap info
I actually went back to the yard and got a 4th gen f-body steering shaft and installed the end on the astro shaft that I bought. That way I didnt have to modify the steering column.

^ thank you. I'm very much a visual person, so that video helps dramatically. Descriptions just don't do me much good, heh.

He's sold a bunch of these things on montecarloss.com, maliburacing.com, gbodyforum.com, and s10forum.com.
He get's compliments on his work and he ships pretty fast.
You'll have to do just a little grinding with his though. I think some of these guys are grinding off way more than they need to. I read about one guy who just slammed the bolt through with a hammer then he could easily take the bolt out and put it back in by hand. This is speculation on my part though as I haven't done the mod yet.
The following is INCORRECT info that I reposted. Someone tried this kit and found that the plastic piece works but the bearing doesn't.
Also from someone else's post it seems the whole bearing assembly is available new from Ebay, Amazon etc. as a Jeep part under Crown PT# 4487696K.

That forth gen bearing retainer in the vid looks nice to me. I'd go with that if I could find one.

If people wouldn't destroy the parts around them that they don't need the situation would be better.

Re: 97 Astro Van Steering Shaft Swap info
Yea if ya want one you better be quick.
From what I've seen he has a partial list of people before he has them in his hands.
Best bet is to watch for him to post on one of his for sale threads on the G-Body sites I mentioned.
He usually mentions he'll be getting some soon, that's when you PM him and get on the list.

Re: 97 Astro Van Steering Shaft Swap info
Here's a thought for you.
My town has a couple companies that specialize in supplying bearings to local shops.
Often times OEM machines are equipped with bearings that don't have the code on them. That way you don't know what the bearing is and you order from that company again using part numbers from out of the manufacturers parts book. Those numbers still don't tell you what the bearing code is. It's either that or the bearings are supplied to the companies in bulk and are not labled as a cost cutter. You know .01% cheaper per bearing lol.
Very often the companies that the machines came from had HUGE mark ups on the bearings. I remember one of them was a very strange looking $250.00 bearing. We took that down to the bearing shop and left it with them for about a week. They came up with the same exact bearing for $25 bucks! To top it off they can usually come up with a higher quality bearing for a lot less money. At times they can't find a match and you're stuck paying the inflated price, PLUS SHIPPING!!!
Once I get a bearing I'll take it down there and see if they can match it up to something and tell me what the code is. That way I can post the numbers and we can get nice new bearings for cheap.
Two problems here.
1. I don't know if they deal with private citizens
2. I don't have a bearing

This vid isn't so much to show the bearing but to show the nice little collar. It just covers the bearing a little more and looks cleaner overall.

Re: 97 Astro Van Steering Shaft Swap info
Yes, the jeep bearing works if you file or dermel the entire keyed area of the lower shaft. I would recommend if you are going to do the bearing upgrade/replacement, be prepared to spend time dremeling the entire keyed area so you don’t have to use a mallet to force the bearing on. I wish I would have waited until I went to work to made a go/no-go gauge out of metal, because I rushed the dremeling and used a mallet be force it on. Bad idea, because it damaged the bearing and loosened it up. My sockets did not bear on it well so I was not only on the center of the bear. It still works but it is not as tight as I hoped. Actually, I do not think it is any tighter then the original bushing I removed. Maybe that is why the engineers did not use a bearing in the first place, because of the process used to form the keyed part of the lower shaft. Plan to go to work and ask one of my friends if there is a good material to shim the bushing and the outer metal of the steering column to tighten it up.

Re: 97 Astro Van Steering Shaft Swap info
FYI, this was the bearing on a 99 Astro van... quite different than the earlier versions I see you guys found. There was no metal ring or clip, and the plastic holder is about 3 inches tall.
The intermediate shaft looks the same as the photos posted from other years though.

Re: 97 Astro Van Steering Shaft Swap info
Were you able to pop the bushing out or something and put the bearing in place of the old bushing? like take the bushing out of the plastic outer retaining ring and put the metal bearing in its place?? I did not know that were was a difference in years and when i went to the scrap yard today i found exactly what you found.
were you able to put the bearing to use after getting it out of the gray plastic housing??
