I just checked it with one wheel on the ground, two complete turns of the wheel gives me 1.75 turns of the drive shart. In my start post I had both wheels off the ground. This still does not add up.
Numbers I found on the pinion housing are 707340, does this tell you anything to gear ratio??
it's there someplace - need one wheel on the ground if it's not posi - mark the tire, turn the driveshaft 2 full turns
