People seem to prefer Neapco 1-0005 u-joints.

 

Those are not studs on the output flange, they are bolts.
You will need to use a small ball peen hammer and pound them out of their holes.
Same thing on the diff side.

 

Man, I shouldn't post when I'm swamped at work. LOL
You're absolutely right, the bolts on the output flange. But on all of mine aren't in that tight, just needed to remove the mud shield and they came out easily.

 

get back to work!!

 

so, what did you DO?

how'd you get the damn nut off?

 

Bought the special set of sockets from harbor freight and they came right off. Just rotate the drive shaft so you can fit the socket in. The sockets worked great. Did both the front and rear drive shaft as well as the rotoflex. Only a slight vibration at 40 and 60 mph.
