warren and all; inthe process of setting up 4 wheel disc brakes on a mopar, you do run into the ''end play dilemma''. too much and you have ''lots'' of free pedal and too little and you take the chance of burning out axle brgs from too much preload. im a bit spoiled in the lube dept. as i use pro blend grease [pro=blend, an additive that REALLY works to cut friction and extend brg. life, its almost impossible to burn out a brg with the stuff in good supply];; at any rate ive learned to set the end play from .002=.004 with 2 being preferred .. i see the effects of expansion, i/e dramatically polished button prints in the axle ends, but even in tucson az [110=115 air temps] ive never put away an axle brg;; but i wouldnt try it w/o the pro=blend as im sure itd burn a brg..
