5.2 Swap...now busted rear spider gears

Recently swapped a 98 5.2 into my 92 YJ, used Dakota bell housing, bolted to AX15, etc. Great swap, took more time than I was expecting, wiring was fun, but forums helped tremendously and everything went together great, great power, great overall conversion. Had 4 cyl, so front axles are Dana 30 and rear Dana 35. Just finished this up 2 weeks ago, and after hitting the gas a little too hard, tore up rear axle gears, now rear spider gears have 4-5+ broken teeth. Jeep currently has 35" tires, 4" leaf spring lift plus ~1.5" shackle lift, and also have the Procomp 5" coil spring conversion that I planned to use, but just haven't yet.

Anyway, now need to upgrade axles, looking for suggestions for front and rear, and wanting to do something with auto-lockers, or something I can drive daily on highway. Have coil spring conversion kit, so thinking might could use axles for coil springs, depending on what I can find and what is recommended.

Thanks in advance for any guidance!

Pick up a Ford 8.8 for the rear , its your best bet, slightly stronger then a DANA 44, and swap kits are everywhere.


Old Jeep that was totaled (and SOLD!):

If you get a 8.8 make sure if you plan on putting lockers in it you get the open differential and not the LSD. You will need to change everything out if you get the LSD. Although for a daily driver the LSD is not bad at all. Ford puts that behind the 302 V8 in Mustangs and I know they spin both wheels with no problem at all. It will also save you $$$. For the front just leave the Dana 30 in there and have a Dana 44 waiting for when it goes. That front actually takes a good amount of abuse. I know it outlasts the Dana 35 regularly.
