you need to rear the t-case at the yoke itself. put a socket on the shaft and put the angle finder on the bottom of it.

i know i'm probably making this harder than it has to be, but i'm not getting consistant measurements. Can someone make an idiots guide for me? Or at least pictures so i can make sure i'm measuring off the right points.

This is with about a 1 inch drop. I am going to remove the 3 degree shims and check again. Unless yall think that's a bad idea?

Ok drop put in today. Went with a 3/4 drop. Took the rear shims out. Put her back on her feet and took more measurements. Looks to be even angles still.

My original setup when I bought it was 4" RC lift, 1 - 1 1/2 inch TC drop, and a mild shim, maybe 3 degrees. It drove perfectly smooth like that.

you should do one thing at a time then drive it then do the next thing (rear shim removal) then drive it.

exactly what kabob said. Wait until you get into having a DC shaft and have to math it out that changing your differential angle also changes the driveshaft angle and will muff up your calculations.

My difference is -5*, but adding 2*'s in shims will put me +1 because of that. Not all shims are equal/exact, some are thicker and raising the axle affects things, contoured vs flat etc. A lot of trial and error.
