Someone is going to have to school me on all the different axles. cAD, non-CAD, High and low pinion, open carrier, locked, I'm new to axles. All I've done is change gear oil, tomorrow I change axle seals in dads f150 but I've not done anything outside of that. I'd like to do everything myself because #1 at 18 money is rare, #2 I like learning new things and #3 it gives me a sense of accomplishment
