you adjust the angle of the yoke, ultimately you have to "rotate" your axle to acheive a good pinion angle. If you have a SYE w/ a C.V. driveshaft then adjust your pinion angle by rotating your axle until the yoke on your axle and your double cardon inline w/ eachother, to adjust your pinion angle first make sure your lower control arms at correct lenght and your axle is centered in the wheel well, and take your upper control arm(s) and adjust them out to rotate it foward, or adjust them in to adjust it backwards until your have them line up in the same line plane
