Axle gear numbers

[SolidusJ]

I've always had a hard time when it came to this subject so what better place to learn more about it then here? So there's the ring and pinion gear and the pinion is on the other end where the drive shaft links to and this spins the ring gear in the housing. Now I have 4:56 so the pinon spin 4 time for one full rotation on the ring gear with 56 teeth on it?

Plus the gears spin in one direction for the oil in housing is properly lubed right? On my first tour we used a front diff and mounted in ther rear so shouldn't have burned out due to improper lubrication? Just trying to get a better understanding of this subject.

No, the "4.56" is actually "4.56 rotations of the driveshaft (and pinion gear) for every 1 rotation of the wheel (or ring gear)

to figure out a gear ratio of any given ring and pinion, divide the number of teeth on the ring gear by the number of teeth on the pinion gear.

Example: if a ring gear has 41 teeth and the pinion gear has 9 teeth, 41 divided by 9 is 4.5555556. So your gear ratio is 4.56:1.

If you use a front axle in a rear configuration, the wheels would spin the opposite way (because in a front axle situation the pinion enters behind the ring gear, and in the rear axle the pinion enters in front of the ring gear) so to use a front axle in the rear you have to flip the differential upside down to get the wheels turning the right direction, which yes, can cause issues preventing oil from reaching the pinion shaft bearings.

Cool thanks for the info!!!
