Is it leaking out of the left (drivers) side of the diff? could be an axle seal.

Good thought :)but the drip is right on the bottom center of the case split.

I vote you fix it with JB Weld!

Seriously...no idea on this one. I checked around online and didn't find much. Hoping it's not an expensive fix.

Tim,
That's how front diff's ask for E-lockers.:D

Sounds like you need the case halfs resealed, done lots of them here...

just tighten up the bolts on diff, i had to take mine apart and silcone it and put it back together there easy to take apart its just sucks getting it out of the truck by yourself
my bolts kept backing out on me so i put some blue thread locker on the bolts

so what if your axle seal is leaking? is that a fairly straightforward fix or do i need to visit the mechanic?

Does splitting the case cause the gears to be reset

Dont think so Kevin,

The dealer cleaned the front diff and applied a " new" Gm sealent, no leaks ever since.
