You might want to read my comments in the "transmission" forum about checking axle ratios. If one wheel is on the ground and one is turning freely, the free wheel will turn twice as many revolutions per driveshaft revolution as the axle ratio would indicate. Thusly, if you turn the driveshaft 10 revolutions and the free wheel turns 5 revolutions, your axle ratio is 10 divided by 2.5 ( not by 5), or a ratio of 4.0. Your axle ratio is probably 3.5, and not 1.75.
