Axle/Gears: 3.73
41/11 and 41/12
they are the gear ratios. 41 is the number of teeth on the gear and 11 is the number of teeth in the input gear. 41/11 = 3.73 41/12 = 3.42 as far as miles the gears look great i have no idea when they were actually replaced. if i had a use for them id keep them. as for posi i forget how to check. when i spin the drive shaft end. only one wheel moves. i believe that means they are open. not sure how to check
