OK, what do shims look like for adjusting pinion angle? 
Are they single wedge-shaped pieces that only go between the spring and axle spring mount plate?
I replaced the springs on my 1976 CJ7 (SOA, D44s, D300) and now I have a grinding sound that starts at about 25mph up. I did not go over 40, but it was still there. It stops when I let up on the gas, but as long as I am keeping a steady speed or accelerating, the sound is there.
I also have a vibration at about 35mph, but that was there before, I think from the Yokohama MTs. I built a spring pack from Wrangler springs, and there were thin metal pieces between each spring leaf. I assumed these were only for allowing movement, but were they actually wedges and I have now screwed up the pinion angle? It looks about the same as it was, but I never measured it before I started this. HELP!
