Rear Diff. Fluid Change Rd. 2

[CapitalTruck]

So I did my second rear diff change today. I've been doing it every 75k miles. Much less debris on the magnet this second time around. With this in mind, I would suggest that everybody change theirs at least once to get the production scrap metal out. The second time might not be completely necessary (especially since synthetic fill is the spec.), however, it sure can't hurt. Every 75k miles isn't too much trouble.

both front and rear gets done every 2 years due to the amount of 4WD usage in the winter, along with the transfer case. After having 1 G-80 gov lock go kablooey on me, I sure as hell am not going to pay $1600+ for a new one on this truck.
