Please help me out. I THINK the difference in preload numbers MIGHT be: my #'s are preload on just pinion gear and nothing else. your #'s COULD be pinion preload after carrier and axle shafts are installed. I have read somewhere that the additional force with carrier and axle shafts installed should add "X" % of force in inch pounds. (added to .015-.019) and that would put it in the range of your #'s. I say your #'s because you pointed it out. I called local dealer and had them look it up per V.I.N. he gave me the same # you did. Later I recalled reading about pinion only and all together #'s.
Does this sound correct?? Ayone? I will call West Coast Diff. Friday for more advice.
