Hate to be a bubble burster, but with diff drop, the prop shaft CV boot tears since you lower the front diff a few inches. I am on my second prop shaft. Of course, that is much easier to change and find replacements since any TOD trooper/SLX fits. Just food for thought.
Took it to a driveline specialty shop, they couldnt rebuild it since its a flanged on boot. Could probably rig something up using a cv boot though...or just have a custom driveshaft made, U-joints instead. I would guess <500 bucks?
