So my driveshaft in my 62 Safari project had a Frankenstein engine swap. I was doing the basic maintenance and noticed the slip yoke for the th400 doesn’t have near the proper engagement. As luck would have it I have a shaft laying around that is the right length. i****umed that the unjoints in the shaft were 3r based on a quick look. So I bought some combo joints to swap the slip yoke onto the other shaft. rear, pictures looks like a 3r. You can see the inside clip. The slip yoke however I can’t find any clips. Inside or outside. It does however have these orange things sticking out. Are those pins? I’ve never seen a u joint with caps held in place by pins. Width is 3.6xx so correct for a 3r any idea here?
It's kinda a molten fiberglass that's injected into a groove in the driveshaft and cap. Usually have to heat the shaft with a torch and the fiberglass type stuff will start to come out, then remove the joint as usual. Don't get it too hot, or the cap can blow off and put a hole in the ceiling or worse. Don't ask how I know! You may be able to remove the joint, without heat, but will probably wreck something. The stuff is pretty tough. Once apart, clean out the groove. You will need a u joint with inside clips to replace. If you have a yoke like that, and the shaft has outside clips, you will need some sort of conversion joint. Most driveshaft shops could help you with that. Bill
Yep that's how I handle them at work! A torch, a little heat around the cups and then watch the show. It's like an adult version of kids 4th of July snakes. The nylon just starts growing out of the little holes. As also stated it's a major pain trying to do it without first heating and removing the nylon. Had customers bring in their messed up yokes and shafts after beating the hell out of them trying to get them apart without heating. Once you get them apart I always take a ice pic and clean the rest of the nylon out of the grooves in the yokes etc. That way I don't have a piece come out and try and bind the new cups going in. .. ...
I’m light on heat. I had a little butane torch that I worked with as best I could then I just gorillaed them loose in my Vice. Thought I was going to pull the top off the table but they finally broke. I think the joints that I got will still work though. They are inside clip
I've never used heat, just drive them out. That's what an original 3R ujoint looks like, there can't be many left that have not been replaced in the past 50+ years.
Those are covered in the Carquest U-Joint catalog. A great resource for sure. http://www.carquestprofessionals.com/catalogs/drivetrain/2013_UJ_CATALOG_CQ.PDF
