I am having problems with the u joints. According to the manual there are cap screws that need to be removed. My truck does not seem to have these at either the front or mid u joint? The ball joint only seems to move back 2+" Any help would be greatly appreciated.

If you drop the center bearing support, it will give you more wiggle room. | | | | | Joined: Nov 2005 Posts: 6,100 'Bolter | | 'Bolter Joined: Nov 2005 Posts: 6,100 | Hy tracermc, welcome, please remember to tell us what year and size of truck you're asking about, lots of different engineering over the years. | | | | | Joined: Jan 2010 Posts: 120 Shop Shark | | Shop Shark Joined: Jan 2010 Posts: 120 | I have a '47 1.5 ton.
4 speed box, 20" dual wheels.
There is a uni at the back of the gearbox, one behind the centre bearing, and one on the diff pinion. Its a two piece shaft, all exposed, no torque tube.
Each uni is held in place with two u bolts in one plane, and fully captive on the other plane.
I'm figuring you have something different?
I undid the ubolts and it all wiggled off. As Crenwelge said, drop the centre bearing and it should come off.

The front u joint has the snap rings holding the bearing cups but the rings can't be reached to undo. The mid carrier u joint does not have snap rings and seems to have a different set up than what the manual describes. Any advise would be greatly apprciated.
