Yep its off. i think the rule of thumb is to use a shim with the number of degrees as number of inches of lift you have. For example, use a 3 degree shim for a 3 inch lift

+1 to what freegdr mentioned.
With an SYE you want the axle pinion yoke pointed directly at the transfer case output yoke. The single cardan joint should look straight when flat (DS and pinion parallel)

Wrong axle piviots up under load decreasing what is all ready to far in. shimming will get same result you could see if your front shafts shorter and try it in rear.jm2cw and 30 years auto knowledge.
