First and most important money factory ..
1. New Axle ( Corporate 14B ) means here around 400 bucks ( with 4.56 and detroit )
2. New Axle ( 14B ) needs rebuild that are about 250 - 300 bucks in seals bearings etc ..
3. 14B FF are 8 lugs means new wheels .. or spacers to 6 lugs .. means more money on it.
4. 14B loose clearance so to compensate .. new tires .. ? I think in bigger .. so 42" TSL
5. 42" TSL rears .. and what to run in front to handle 42" .. ?
At the end it looks like I would need much more money to swap the rear and keep the actual performance ..
I found that with 12" of clearance I can go most of the places here and still drive my Cruiser long distance to reach the fun .. and no need to towing it.
I thought at the end it's a matter of kind of off road that we do down here ..
Sounds like a good decision and I (like you already know) think you wont have any problems out of those axles.
