Fix my mistake as a direct result of procrastination.
Front differential bearings with 15k miles on them. Long story short my ARB lockers had bad bonded piston seals and the axle seals did not survive the second time around. The very slow leak that I was topping off all the sudden one day dumped a ton of fluid and I burnt the pinion bearing..
250 dollar mistake plus seals.
Took the time to do upper ball joints, front differential bushing and cv's.
