Everything is tight. Just checked it. After reading ypur "Driveline 101" I have come to the conslusion that the front and rear angles are pretty much in line with each other and are equal. From reading your stuff, I see that 1-2 degrees lower in the rear is preferred. I have 6 degree shims on there right now. So I guess maybe I need 5 degree shims to lower the rear angle? Am I thinking right on this? It is almost tolerable noise right now so I probably shouldn't go all the way to 4 degree shims I am thinking. Let me know what you think and I'll order some from you.
