Re: Changing Front Differential Fluid
Over Christmas my yearlong project came to fruition and I picked up my 2010 SMB in Las Vegas, nicked named Kitten for being so small and inconspicuous. She has front and rear Dynatrac, each with ARB air lockers. The Atlas transfer case requires a lube change at 500 miles and the ARB air lockers require a lube change of both differentials after 1500 mile break in period. I was having too much fun to get that far in the manual until I returned home to Portland. Has everyone done these changes after the manufacturer specified break in period? Of those who have done this job themselves, is it pretty involved or similar to changing oil and transmission fluid. Open the drain, and refill? What volume of lube is required for each component? I hear 2 quarts for the Atlas transfer case, but unable to find information on the differentials. Last question is the differential lube recommended for Dynatrac is Synthetic 85W140 GL6 or 75W140 GL5. Other forums stated that for our particular setup, GL6 is preferred. Have you used either?
Your thoughts are appreciated.
