Default front drive shaft modification for scout II

I have a '73 Scout II. I've put on a 4" (SUA) suspension lift with six degree castor wedges. Front driveshaft binds. I've heard of modification of the front drive shaft with cv joints. Question is, if this is true, where do I get this item or get this item manufactured.

You should really take the rig to a driveline expert/shop and have them look at it and make a recommendation. In fact, I just went through this last week with my own rig regarding a rear driveline, and I'm involved now with having them cut down the rear driveline I removed from my rig to put in the front of a heavily modded/lifted Scout 80/800/II bastard child.

I "thought" I knew stuff about drivelines, cv joints, shaft angles, etc. Until I talked to the man and he straightened me out! And ended up saving me a bunch of dinero since a cv system was not correct for what I thought I needed!

Playing around with driveshaft systems that are not correct is not something I'll ever do again. A good friend in college died when his homebrew driveshaft let go and sawed the vehicle (and him) in half at speed.
Are yawl ready??? If not here's some training ya might need to prepare:

Also -- if you didn't change the pinion angle ont he axle with a purpose a cv front shaft will probably not help the situation much.

To just gloss over the technical stuff -- in general:

for a standard driveline you want the angles of the output of the t-case and the input of the pinion to be parallel (opposite angles if you measure them -- if the t-case points down 4 degree the pinion needs to point up 4 degrees...)

for a cv driveline you need the pinion to point directly at the output of the t-case.

6 shims and 4" lift is your problem.

Remove the shims (or go with something less aggressive) or remove the lift or cut-n-turn or a special "Tom woods off-set u-joint" are your solutions.
