![]() Hello,
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. Thanks, keith |

![]() 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.

![]() 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. |

![]() 6º 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. |
