Did a gravity bleed on my 4.6is brakes earlier. One nice thing about these 20's and off road tires is I can use my creeper and roll underneath it and open up the bleed screw without taking the wheels off.No jack stands or anything. I am going to change the rear diff fluid just by rolling underneath. Space is a bit tight, but very manageable.
