So, I decided to bust into the Stealth in one of the 10Ts I recently purchased. When the truck first arrived I of course gave it a once-over and grabbed the spur to see how the diff felt. Well, it wasn't real promising so I put the whole thing away for a bit.
Popped it open tonight to see this:
and this:
Yep, NO diff rings (still had diff balls though!

) and black grease that is more like 200,000 mile oil that hasn't been changed...
So, I bagged all this up and I'll continue another day after I get some stuff ordered!
Just a little cleaning (HA!), some diff rings, new diff balls, new bearings and I'll be back in business!
