Another thread on rear diff. lubricant.....
I didn't want to hack the other thread going on with rear diff. questions, but it influenced me to post my issue with my rear diff. I have a 2003 Chevrolet Tahoe, 5.3 4x4 133,000 miles. About two yea...

Servicing a diff is super easy so I suggest you do it yourself.
Drain the fluid into a pan and check the bottom of it for metal. If you find anything like this:
Then you have trouble and you should get it into a shop for repair NOW. If you keep driving it like that, the bits of metal will go through the gears and eventually destroy them - which will cost you another $600~$750 beyond what the rebuild costs.
BTW, those bits are from my spider gears and while you'd think they were just common metal, they must be gold because there's $2300 worth of that stuff there :(
