I just went through a similar discussion about modified Jeeps and inexperienced Jeep owners. Most folks have no idea how much money a highly modified Jeep takes to keep running. Those big angles created by the lift, as well as all the leverage the big tires add to the drivetrain cost plenty to keep running. Once you start getting that big and especially if the vehicle has been used off-road, things break. If you have deep pockets and good mechanical ability, buying a modded Jeep is a great way to go, but be prepared for major expenses... $400 for a driveshaft plus your labor to replace it is pretty common for example. Axles and U-joints are common failure points with tires the size you mention. Steering boxes can break. That nice Warn front hub conversion is really cool and work great, but getting bearings and seals when they are needed can be easier said than done depending on where you live.
From the looks of that Jeep, I can't imagine it has no CV driveshaft. More likely the driveshaft needs to be rebuilt. With the steep angles, if you don't grease those joints every oil change, they will go out very quickly.
If you are unsure, I recommend taking it to a good 4x4 shop for a vehicle evaluation before putting down a penny.
