Sooo, is my differential eating itself?

Is my rear differential eating itself or is this normal? Last changed the diff fluid about 35k miles ago with the install of a Detroit Trutrac. Is this normal after installing a gear-based LSD?

 

Plug looks ok to me, did the fluid look like a metallic milkshake?

 

Not terrible, I wouldnt worry unless there was an abnormal noise associated to the rear diff.

 

Yep exactly. Basically looked like watery anti-seize. It just seemed like a lot of build up.

 

Looks like new gears in your tru trac have been finding their groove with each other. I would say roll on.

 

If this was the case I'd be worried. This happened to me when my bearings were eating themselves. You might want to call the shop that did the gear job
