Front Driveshaft Question for modified CJ

[IH392]

I've been helping a friend do a spring over on his CJ scrambler and installing full width axles. The problem is now the front driveshaft angle is very extreme because the pinion on this front axle is pointing too low. I'm not interested in cutting the tubes of the axle and rotating the housing up because it seems to be a lot of work. The driveshaft is longer than an xj's. I just wondered if using a double cardon on each side of the driveshaft is an option? Anyone ever do this before. The other option is to lower the cross member, which i'd rather not do either, or maybe we should use misalignment ball joints so I can rotate the axle. Curious to what people's thoughts are.

Can you use shims to change the angle?

 

[IH392]

If I shim the axle, than the alignment will be off, but maybe we should try anyways and see how it drives. The castor angle is only a few degrees at the moment, it will only make it worse.

I would call tom woods, and see what they have to say.

I don't believe you can put CVs at both ends, only one end. You don't have options if you do a SOA on a old leaf sprung front end, you need to pull the front end and cut and turn the inner Cs for proper caster and drive line angle. You can also reduce the amount of lift up front and run a high clearance U joint. Tom woods among other have high clearance/high angle U joints.

So if you don't want to cut the knuckles a high clearance U joint and a lot less lift up front are your only options. or Do it right and cut and turn the knuckles.

post pics. how bad of an angle are we talking anyway? it might not be that bad?

wow. I had no idea you could use them at freeway speed

I figured having CVs at both ends would cause the entire unit to go nuts . Although starting at 454$ is pricey. I bet he could have the knuckles turned for 500$ or less if he cant do it himself for free. plus you get into the issue of trail spares- double CV shafts are not common and rebuilding a double CV shaft like that will probably cost an ass, arm and elbow.
