This is my rear axle assembly. Speed bleeders point up and the calipers are on the rearward facing side of the axle assembly. If you look at the driveshaft you will see the drum parking brake on the back of the d18 transfer case. I kind of don't understand your question I think. On another note I set a dial indicator on this same side and got .015 runout. Found my pulsating pedal. recut the rotor/hub assembly and its all good now. Brakes work great now. I didn't realize how noisy my old tapered d44 was until I swapped this one in. Clunking, vibration, friction too. I am stoked!
