Like tanks said, the Dana 35 is your weak link. It WILL NOT handle the 36's. You call the jeep your baby, you better baby it ALOT.
The 4" suspension isnt enough to clear 36's either. Unless you keep it on the street. I have 8.5 inches of lift with a set of 35's on mine, and i can get it to rub the tires very easily. Do the math, 36" tires are 8" taller than the stock tire that came on the vehicle, add in the factor of body roll since you are sitting taller, and you would need atleast 10" of lift to clear 36's without them rubbing at some point.
Just my point of view, i'm sure there are others out there that will disagree with me, but, if i spent 250-300 per tire, the last thing i want to happen is being in an off camber spot where my body is going to take a chunk out of that expensive piece of rubber.
