Agreed. I would just be interested on any data and the type of off roading done. I check mine every oil change and I have a SS 1.2 lift on mine. I put new LBJ in when I did the lift. Rig has 258k on it and I figured it was time.
99 sport or limited in black with the multimode 4x4 center diff and the rear elocker. Best of both worlds. Hard to find. All years are pretty reliable.
