Rear diff pics

[MountaineerTom]

A few weeks ago I changed the rear diff fluid in my truck.  The first pic shows all the "sludge" that was collected by the magnet.  This just was after 22,000 miles.  The second and third pic shows it before and after I cleaned it up.  And last, but not least, my diff cover that I painted while I had it off.  I painted it with Rust-Oleum Metalic Finish Aluminium paint.  It says "Metallized for a rich finish" on the can.  Also, I used Valvoline Synthetic 75w-90 gear oil and a GM gasket.  I thought this might be some usefull info for those wondering about changing the diff fluid.
