Bad vibration on acceleration
I just replaced my u-joints on my rear driveshaft on my 92, but when I was removing everything, the hyme joint fell apart, all the bearings in it fell out. I asked around to see if anyone knew how to remove it, but no one knew how, so I ended up putting it all back together with out replacing it. Well got it back in the truck and took it for a test drive and now I have really bad vibration on acceleration, but not when I am coasting. I don’t think that the driveshaft is out of balance but I have been proven to be wrong a lot, I think it might be that hyme joint. Any input would be grateful and anyone knows how to replace the hyme joint?

Are you saying all the needle bearings fell out of the end caps? If so, they could have been re-intstalled, using wheel bearing grease to hold them in place.
My '88 has the double cardan (sp?) joint at the front, which is tough to deal with. After one home rebuild that lasted less than two years. I finally took the driveshaft to a specialty shop because a new "trunion" had to be welded on and the unit balanced properly. Works great now.

Needle bearings
Yes they all fell out, but the holder just pops out, you can buy a replacement for about 20 bucks which I did, has the holder and all new needle bearings, aster i replaced it no more vibration and it was very easy to do, i just poped the holder in with a socket that matched the diameter of the needle bearing holder

Wait a minute, a "heim" joint is the type use in high performance tierod ends! The rear DS on a Bronco uses a standard universal joint at the pinion yoke, a slip-yoke (splined, variable length shaft) and a double-cardon universal joint at the front of the DS into the transfer case output flange. The centering ball and spring assembly in the double-cardon U-joint is often the culprit when dealing with driveline vibration. It can be replaced but requires a vice to hold things while you do the work. I've had them replaced before but just let the shop do it. I do know that it can and has been done by DIY/shade-tree mechanics.
big1992, glad to hear you got the problem resolved anyway.

centering ball and spring assembly
centering ball and spring assembly ,thats what i meant, I just went along with the term used by the first post, but i did my own centering ball and spring assembly, mine just popped out and I put the new one in with a socket that fit the outside diameter...
