i have 2001 suburban. i had to rebuild the rear end. i replaced every but carrier housing. set up wear pattern to what i thought it should be. i did some reading on it. had back lash at .005 and put .010 preload on carrier bearings. when i did crush collar i preloaded it to 14in.lbs on dial torque wrench. proble is i have slight whine from 60 to 40 mph on coast . also have vibration at 65 mph. question is to you think i set bearing preload wrong or something else. any advice would be a big help:
