Changed the front at 3000 and same thing. The oil was a mustard yellow color and there was gunk on the plug. What came out from the factory was a pint low.
The rear was changed at 3000. it was black and there was a lot of fine silvery particles. Make sure you used a synthetic in the rear actually GM states to use only their proprietary axle oil or one that meets their spec... No one meets there spec. Oh well
