Nissan 39100-1AA0B Axle Assembly

The power is taken from the transaxle and the rear differential in the all wheel drive models through two axle shafts, on the one side of which are the splined side gears of the differential and the other is splined to the axle hub and fixed by a nut. The inner ends of the output shafts contain tripod type CVs having both angular freedoms and axial freedoms, while the outer ones are ball and cage type. Tracking of boots for tear and leakage of the lubricant is required because separated boots of the CV joint need to be replaced to avoid joint abrasion. CV joint wear and damage symptoms include lubricant leakage on the outside of boot lips, a clicking sound while turning, a clunk when accelerating from a stop and smoothest vibration while driving at high speeds. To inspect the wear of CV joints and axle shafts, just grab the axles and twist them by hands, holding the CV joints with your hands, try to listen or feel vibrations that would show you that the splines are worn or that the CV joints are loose while grabbing the axle shafts.
