Today I tried the rotations method. I jacked the whole back axle off the ground. After one rotations, the shaft spun 1.75 times. After two, it had spun somewhere between 3.5 and 3.75 times. I assume that i probably have 3.55 or 3.73 gears in back. However, in the front. I couldnt get the shaft to spin. I tried it in 4wd in and out of gear. Nothing. Any ideas. Also, I want to get lower(numerically higher) gears cause i have a lift and 35's.
