Make sure to keep the A4LD cool. If you don't already, add an external cooler. The push push button case, and matching auto hubs are fine for street use, but undoubtedly will fail when you need it most. You can still get manual hubs and conversion kits from the after market, not as convenient, but I tortured my 94 explorer with 33's and generous skinny pedal. I never bounced the thing on rocks, or did anything more than Uwharrie, but there were several times tires where off the ground, and I drug axles through the mud, and even bottomed a time or three.
I'd suggest swapping in an explorer 8.8, disk or drum will give you 31 spline axles, disk has a built in axle retainer. I don't remember exactly, but if you don't have them, swap on the knuckles from a 96 or 97 ranger and get the advantage of bolt on dual piston calipers.
