kinda hard to see but i have the leaf perches set so the pinion is angled just right. the pinion is angled a tiny bit lower than perfect to compensate for the axle wrap when under load.

to adjsut the pinion angle, i left the u-bolts loose. i had tires on and with full weight applied so it was at ride height. i used a straight edge to determine what angle i needed (double cardan driveshafts want pinion pointed right at the transfer case output). i used a jack on the pinion to force the axle to spin till proper angle was achieved. then i tightened the u-bolts. my welder will not reach the trucks location so i will weld it later

the lift block is completely on the spring perch. an issue i see on stock perches is the lift block overhangs the perch and makes axlewrap more likely.
