I have the worst possible set up. low pinion front diff and a v6 transfer case. My problem is getting my front driveshaft to reach the pinion flange at that angle. I had my i.f.s driveshaft lengthened to reach (with 8 inches of slip) but the ifs c.v. joint dosent have enough angle (it only flexes to 25degrees) i know the older trucks 86 and older had 10 degress more angle and those will flex to 35 degrees. I guess im looking for someone that is mabye running my same setup. and knows wether or not a C.V. out of a older truck will cure my problem? Thanks guys

Try clearancing the CV for more travel:

Or swap it for a u-joint.

thats what im hearing now. i had always thought cvs were better the steeper the angle. but im reading different now!!!

Well, yes and no. All depends on what you are trying to do. A CV joint is good for steeper angles where you want to run at high speeds without vibration:

But a CV joint (at least the kind used on Toyota driveshafts) generally have two drawbacks:

1. Less angularity than a u-joint. As noted, even a clearanced or solid axle CV is good for maybe 35 degrees before it binds. A u-joint can probably go to 45 degrees and still work.

2. A CV joint is longer overall than a u-joint. What difference does that make? Well, driveshaft slope is a function of it's rise (vertical height difference) and it's run (horizontal separation of the two ends). Can't change the rise, but by putting in a shorter u-joint on the top, you make the useful horizontal distance longer. Since all the angle change in a u-joint happens right at the u-joint cross bearing, compared to a CV joint where you get part of the angle change at the 1st u-joint section and part at the 2nd section.

Other option is to cut and rotate the front steering knuckles for better pinion angle:

Or slap in a high pinion diff (less rise) or slap in a 2nd transfer case (more run), both of which mean less angle on the front shaft. I run both on mine and have almost a perfect front shaft alignment with a CV joint.

i ran a High Angle V6 flange on mine until i swapped in a 4cyl case. it allows you to run standard u-joints up front. i'm selling it if you're interested...
