I've had my Cummins for just over 30,000 miles now and this weekend I figured I better change the gear oil in the axles since the factory recommends changing it ever 15,000 miles. Whoops! Rear axle looked just fine, then I cracked open the front axle and this is what I got . . . So i hosed everything down with 3M brake cleaner and cleaned everything up and filled her full of new 80w-90. Think it was just the silicon on the diff cover leaking? Needless to say I'm keeping a record book of maintenance now.
