Got the front and rear drivelines in but my angles are off. Here is the stats: Front - 6 inch TC springs on a D60. Measurements are: TC =4 degrees up Driveshaft =24 degrees down Pinion =5 degrees down Anybody proficient on calculating what shims I need for the front? Rear - Corp14ff on 4 inch ORD shackle reversal, 4 inch TC springs, 1 inch ORD zero rate. TC=4 degrees down Driveshaft=24 degrees down Pinion=13 degrees down According to several articles, I'm supposed to subtract 2 degrees for axle wrap in the rear. So, my calculations show I need an 11 degree shim in the rear to put it 2 degrees low which levels it out under load and keeps the pinion in line with the driveshaft. The driveline is a 1350 CV from High Angle Driveline. I have an e-mail into Jesse too. So, is an 11 degree shim too much? I really don't want to cut and re-weld the spring perches. I also sit 1 inch high in the rear right down which I had planned on leaving so that after loading the rig with gear it would sit level. If I pulled the zero rate, it would sit level empty. However, this would probably reduce my angles a bit. Recommendations? Anybody else in this boat before? Looks like JKW Offroad makes 10 degree shims now and can custom makes some 11's for me.
