Toyota Pickup Axle Gear Ratios

hi i have a 1993 22re toyota pickup extended cab that i lifted and i put a front differential my 1989 22re toyota pickup regular cab pickup in it.

-i forget why i changed it i think something was stripped out on mine when i lifted it so i needed the other differential

-the problem is that when in 4-low i can creep a few feet and the truck will stop and if i give it gas and go past where it stops the rear tires will start digging into the dirt and spinning when the front ones are still creeping along slow.

- so my dad and friend think that the front axle i put in the truck has a different gear ratio then the rear axle that is in the truck

- so what do you think?

- i would really like to have an answer to this question also > are the gear ratios different in 1989 than in 1993 or are the extended cabs geared different than regular cabs
