Drive easy for 30 miles and stop to let the rear cool down. Don't do any extended drives... even at light load. Fresh bearings and gears throw alot of heat.
Of course alot of people will say just drive it, but take a 10 min drive and go under and see how long you can hold your hand on the cover. My bet is not too long
