What parts, from what, are those on the steering shaft, Jeep? Do you have a write up about how you did that? Thanks.
The steering shaft came from a Chevy Express 2500 van, it was a early 2000's model.
It was a huge pain in the ass to pull out of the van... I didn't bring the right tools to get it out, a box cutter and a crow bar is needed. There is a thick rubber sleeve housing the steering shaft from the steering box all the way up to the column and it has to be cut, all I had to cut it with was a flat tip screw driver lol, once the sleeve is off both ends of the shaft are secured with 3/8" bolts, once those are removed the ends are still on attached extremely tight, that'swhen you need the crow bar. Took me about 2.5 hours with none of the right tools, would probably take 30 mins. with the right stuff, still a pain in the ass though.
It fit perfectly onto the lower steering column of my '79 K5 and the input shaft of my '88 steering box.
It took light persuasion with a punch and a hammer to get both ends of the shaft full seated.
I got this one vs. the Jeep XJ shaft because it doesn't have plastic in the shaft that you have to heat up to collapse and I had read that with the XJ shaft some people were having problems with the lower steering column bearing would walk out. The express shaft is seated all the way up on the lower column just a hair away from the bearing so I don't see any problems there.
@cwn anwyn is how I found out about the express steering shaft and he might have more info about it but it's a straight forward install and seems to be a solid upgrade.
