Assuming that you have a 2007 with a bad diff, you can upgrade to the 8.2 and utilize your current axles, but will have to swap the pumpkin as well. It’s not a straight swap, there will need to be some fabricating done.
Search the forum here and you can find a couple of folks that have done just that. I on the other hand replaced my 8.0 with a third member from East Coast Gear Supply and so far it sounds like it just drove off the lot. $750 vs. around $3K to upgrade to 8,2, and it only took me ten hours in the driveway by myself.
Good luck

The OP has stated that he has a 2WD model with locking differential, but hasn’t provided any information on what Is actually wrong with the differential.

the first question might be, EXACTLY what is wrong?
Noisy pinion or carrier bearings?
Mesh whine?
Lubrication failure?
Broken gear teeth?
Non-functional locker mechanism?

To provide any useful information on repair options, we need to know exactly what the problem is.
