Are you saying the front drive shaft on a d2 does not move out of plane with the articulation of solid front axle? Just want to be clear.
I say this in reference to the cross member support beneath the front shaft being removed with a lift. I understand this is getting away from origin of post- I am just sharing my experience with this, not trying to force my opinion. Cheers
Most certainly it moves up and it also would move side to side depending on the axle orientation angles. 100%.
Sounds like the OP is trying to treat the symptom (failed drive shaft) instead of the problem (drive shaft grease failure caused by heating from catalytic converter). Maybe the proper solution is to protect the drive shaft from the radiant heat of the catalytic converter. There are generic heat shields/blankets that can be wrapped around them to contain the heat.
If the cross member is removed then the shaft is increasingly likely to just fail and fall to the ground vs being held up and thrashing the trans. I'm not sure the Jegs hoop would allow for full articulation as to protect things it would need to be located closer to the diff than t-case and that's the side with all the movement. On street car it's probably fine but not so sure about a 4x4 application. If you could build just a upper portion or brace and leave the bottom open, it could help protect trans but it's pretty tight up above the shaft if I'm remembering correctly.
