    Should work fine.

    Measure the driveshaft angle and record it.
    Measure the pinion angle and record it.
    Measure the t-case yoke angle and record it.

    Subtract t-case yoke angle from driveshaft angle to get your front u-joint angle.
    Repeat for pinion to get rear u-joint angle.

    Optimally, they should be within a couple degrees of each other on a street-driven vehicle.

    how do I properly measure the angles, just let the magnet stick on the side so that its flush with the way the pinion, or driveshaft is pointing?

    No, you hang it off the bottom of each piece. The pointer is weighted and will swing to the bottom, then you read the number which will give you degrees off of either horizontal or vertical, depending on which scale you use.

    Take it out of the package and play with it. You should be able to figure it out in five minutes or less.

    That angle finder will work fine. I bought one like it only in fire engine red from Ace hardware for 10.99
    It may be a good idea for you to spend some time here:Driveline 101

    measured

    I put the angle finder on the the following...

    14ff pinion angle = 15*
    driveshaft =7*
    t case output= 4*

    all of these anlges are in an upward slope, being lowest toward the back of the burb, and higher toward the front of the burb..

    I'm having a hard time understanding how all these angles relate together. I know I need to run a shim that will make my pinion point lower. Anybody know what size shim I'll need to make the angles equal?

    Basically, your pinion angle and t-case angle need to be within 2 degrees or so of each other, with the pinion angled slightly lower to compensate for axle wrap.

    Click that link that Thunder posted and it will tell you everything you ever wanted to know.

    I'm guessing a 5* shim should do the trick.

    I'm considering a test drive to make sure I even need to shim, but that pinion angle looks pretty ugly just eyeing it..

    Jess said, assuming I measured my angles right, that I need a 7* shim. I guess I'm going to order a set of 7* steel shims, and I'm going to get a new set of center pins and u bolts, and go from there...

    I wonder if I'll be able to put on the new center pins by just taking off the old u bolts and jacking the truck up untill the springs raise up off the axle? I'll try to rig up some kinda decent jackstands :doah:
