Power steering box Rag Joint

I only said Rag Joint as that was what we called them back in the 70's. I will just replace with the new kits.
For most, The worst part of the rebuild is the cap. Factory used a bottle cap like crimp. The kit will include a new cap and you can find threads here detailing how members have managed to recreate the factory like crimp using the new cap in the kit.
I was taught to distort the original cap just enough to pop it off, like a bottle cap, so I could reinstall it.
The cross pin is a very tight press fit into the shaft. Most of the time it isn't worn enough to warrant R&R. I've replaced only 2 of them. If you do need to replace it you will need a press to get it changed and centered. Disassemble the column, take shaft alone to the press.
I did R&R 1 of the 2 with a hammer. Took some doing to get it close to centered. I settled for about ten thou' of centered. Good luck with yours.
