You have a lift and a stock diveshaft. Its weak and angled crazy...

Get a SYE and stronger/longer/CV style driveshaft

So if i remember right after just reading your setup, you have 32's on the front, 33x12.50's on the rear with a stock dana 35 and a lincon locker in the read diff? with that setup its just a matter of a little bit of time till the weakest point in your drivetrain will break, That being your u joints. be thank ful that they are breaking and not something else more expensive.

Are they breaking in the same situation everytime?
Are you turning when they break?
What type of ground are you on?
What type of u joints are you using?

Try spicers, more expensive but a lot stronger.

Are you using a t case drop or shimming the rear axle?
