    Have a driveshaft made to specifically fit your application.....

    I know, i was just wondering because of the angle at the transfer case, if i get the shaft legnthend it will still be pretty steep.

    They won't stay together. Take my word for it. My friend has the same problem. He's destroyed a half dozen of them already.

    most people add a cv joint setup to the front...thats really the only way to run the extreme angles...check out high angle driveline...the guy that owns it is a member here...i think he goes by drivelinman or something like that...you could do a search for it

    Yep, CV is the only way to fly on pre-76 trucks that came with that yoke up front.

    So did the older trucks (like my '71) come without a CV in the front?

    I was told by a member of this site that the pre-76 trucks are the ones that didn't come with a flange up front.

    I can say for sure that the single U-joint doesn't last long in the front of my friend's truck....he has full time hubs and it destroys itself often before he even hits the mud, on the road on the way there. His angles are insane though.

    Caster (rough definition) is the inclination angle of the spindle, given by the upper and lower control arm to spindle points as comapred to vertical.
    How you measure that on solid axles, I have a good idea, but I'll stay in my little corner and let those more knowledgeable than I answer.
    How you correct it? I have no clue on a solid axle.
    What it affects? The amount your steering wheel wants to return to center after turning, as well as to some extent, the amount steering effort you will need to use to turn the steering wheel off of center.
    It's that whole "car" thing again...
    Pinion angle is the angle of the pinion flange (on the axle) or degree of tilt the pinion has in relation to the other end you are attaching it to. In your situation it's that nifty transfer case thingamob...
    When you have it wrong, you know it! Bad vibrations through the suspension and driveline.
    rare cheese? a good one...
    Ancient language of atlantis? Chicken....

    just a guess but you may consider lowering the t-case as stated earlier. That is a mean angle, I hope it last for you....

    Lowering the tcase will actually hurt your frt shaft angle. If the front u-jt is binding up the angle is too big so you will need to either shim the front pinion angle up more (shims are known for making the truck wander and cause alignment problems... at least w/ the larger degree shims) What size shim is in there now? I would try a 6 degree shim. It will probably handle like crude though. Other options I believe would be getting the knuckle turned (very expensive) or to look into one of the dual CV style shafts. These have a cv at each end of the shaft so it can run at almost any angle.

    what is the best way to measure the driveshaft angle at the transfer case and the axle?
