first thing to do it have the back of the transfer case flanged. Then put a slip youk on the drive shaft at the rear and have the top double cardioned. Try Pats Driveline good work but not cheap.

either...

turn the rear diff up using shims, or a small block with the correct angle...

or cut off the spring perch's and get them re-welded on in a better place for a better angle...

we mpointed the pinion right at the t-case (about a 2 degree angle) and are goign ot run a cv type shaft to get rid of the vibrations.... our top angle is 12 degrees and the rear is 2...

ill take some more picds if you need them

I don't know much about this stuff but the angled blocks in the rear will only fix the rear end portion of the shaft so you will have to do what Hulk said for the transfer case.

same as what i said....cv shaft (cv is a double cardioned shaft...) is need because...

1st reason is because if you do what we did on andys and point the pinion right at the tcase youwill get mad vibrations if rou ran a normal ujoint shaft. The way normal shafts work is the angles of the ujoints are oppisite...so they cancle out eachothers vibrations. When you run and straight angle at the bottom and if you were to run a normal ujoint at the top..there would be no opposite angle to cancle out the vibrations...so it would be mad. The Cv at the top cancles out the vibratinons because there is 2 ujoints it...


heres what pirate says about it


The solution is simple and elegant. If we ensure that the u-joints at each end of the shaft are both "in phase" and operating through exactly the same angle, the pinion end of the driveshaft will speed-up and slow down opposite to the transfer case end, and therefore the different angular velocities cancel one another out, the pinion is driven at a steady rate, and vibration is minimal (if I did a decent job of describing why the elliptical paths happen in the first place - you should be able to prove this to yourself). This works fairly well up to angles approaching the maximum operating angles of the u-joints in question. As the angles grow, so do the magnitude of the accelerations and decelerations, and the less effective the matched angle are at eliminating vibration.

http://www.pirate4x4.com/tech/billavista/PR-shaft/degreecv_small.jpg this is what you should have:D

if this makes no sence...read this it will explain everything

I dont think you can cv a slip yolk...
high angle driveling makes a solid output conversion kit for most tcases depending on themodel that will get rid of the slip yoke...

Shims will help both ends of the driveshaft cus it in effect lifts the input end of the diff rule of thumb for shims is one degree per inch of lift (6" lift use 6 degree shim)

when you run a standard 2 ujoint drive shaft you have to cancel drive line angles so whatever angle your tcase is at you need to set you rear end 1 to2 degrees lower (to account for pinion lifting under load).So if you drop the tcase you need to raise the rear end or if you raise the rear end you need to drop the tcase.
if you run a cv shaft(double cardan) you now only need to raise the rear end angle to run the pinion straight in line with the driveshaft.

can the shims to correct pinion angle, loose the slip yoke thingy at the tranny..... have the slip yoke in the drive shaft.....
