I have a few stupid beginner questions about axles, gear ratios and such.
i have a 97 sport with a d35 in the rear and a 30 in the front with the ax15 transmission.
according to the stock tj spec page, the standard gear ratio for 6 cylinder models is 3.07.
stock gear ratio options available with the d35 are 3.07, 3.55, 3.73, 4.11, 4.56.
the ax15 tranny has 1st - 3.83 2nd - 2.33 3rd - 1.44 4th - 1.00 5th - 0.79 Rev - 4.22.
so basically my stuped question is what do all of these numbers mean?
why is the gear ratio 3.07 while no gear in the transmission is that ratio?
when you upgrade you gears, do you upgrade your front and rear axles, as well as your trans?
how can i find out what my gear ratio is to be positive? im like 99% sure i have a d35 because it has the rubber fluid hole
thank you so much for helping out and im sure ill think of more questions later
