Message	Lately I`ve noticed a slight rear differential whine when I`m accelerating at 60+ mph. The noise only happens under acceleration load,and not when cruising or coasting. Does this seem like it may be a mechanical problem developing,or maybe would a rear diff fluid change be all that is needed? Current fluid is Amsoil AGL 80W90 GL5. It`s been in there probably 5 years and 50,000 miles. Current miles on car is 96,000. If a rear diff fluid change is recommended,what`s the current consensus on the best brand/weight? Thanks!
