My rear diff went out so I was forced to make a change anyway. Did the Expo 8.8 axle swap going from a 3.73 to a 4.10. As has been stated here, its simpler and cheaper doing the swap as I didn't have the skill to rebuild the rear diff. Also had to switch out the front diff to a 4.10 since I had 4WD. Upsized to 31" tires so pretty much a wash.
