I want to do a Spring over Axle Conversion (SOA) on my 94 wrangler. I have been reading everything I can find about it online, and I understand most of it. What I don't understand is changing the driveshaft to a CV shaft, or the whole drive line angle problem, can somebody put this in simple terms for me?

Also what would have to be done with the stearing?

 

The rear driveshaft on the wranglers is extremely short so when you lower the axle six inches or so it puts an extreme angle on the driveshaft joint at the transfercase.A u-joint will only operate correctly over a certain amount of movement and it also make it difficult for the slip joint to move in and out properly. A slip joint eliminator kit will address most of these problems.
Regarding the steering, it's just a matter of making sure the tie rod and drag link don't foul on the springs. You might have to mount the axles and then sort the steering out when you can see exactly how much room you have to work with.
