How was the final contact pattern? Pinion bearing preload can be checked with a beam type torque wrench. Richmond says 15 to 20 miles under normal operating temperatures without creating a shock or towing. Allow to cool completely and repeat 2 to 3 times. I know break creates a lot of heat but 2 hours later and can't keep your hand on the differential? http://www.richmondgear.com/07pdfs/BodyEXCEL.pdf
