Re: Please check my math: Rear End Gearing

NF,
Method 2 works fine with non clutch posi (i.e. open) rear ends. One wheel held static. Spin the other tire two tire rotations and count drive shaft rotations. You have 3.08. The two turns come as a result of the spider gears. One tire rotation would be true if there was a clutch type posi installed (and both tires rotated in the same direction).
