Finally got the spring perches and shock mounts welded to my metric ton MJ Dana 44 limited slip axle, and installed in my 87XJ. I lowered the TC 5/8 inch and rotated the spring perches two degrees down to raise the pinion angle two degrees up before welding. It turned out good, TC yoke angle is 5 1/2degrees down(on level ground with weight on suspension) and pinion is pointing 5 1/2 degrees up(parallel to TC yoke). Drive shaft angle is 11 degrees. That leaves both u-joints in phaze swinging through 5 1/2 degrees. Any body know if the 5 1/2 degrees u-joint angle is excessive. I have a slight vibration with onset at about 65mph.
