Ok this will be long so you guys can see what i did wrong. I swapped in my sm465/205 and had a new drive shaft with 1350 ujoints. well i didn't get yokes so i couldn't use it and i really need my truck to get me from work to home, so i drove it in 4hi running off of just the front drive shaft. Well the ujoints in the front shaft were shot and i broke the shaft. So i got a new yoke for the 205 and was going to get one for my 12 bolt. The shop told me i had to bring in my old one to match it up, so i took it off and they said they would have to order a special one so i just asked for the conversion ujoint for it and used the old yoke. I got it all together today and went to drive it, but i have some kind of binding in the rear end. I have only driven it a coulple hundred feet and i get a good binding in foward motion, none in reverse. It's some what brief then unbinds then i can move another 10 feet or so then it binds again. I only went as fast as 5 miles an hour to not break anything, but the binding will stop me right away. Could it have been that i didn't put the yoke back on the 12 bolt right? Or is my driveshaft binding? when i put the conversion ujoint in could i have made it to tight? Thanks for the help in advance.
