So exotic kustoms replaced my ring and pinion for free. They said they would do the gear break in routine, but should I go ahead and do it as well once I pick up the truck tomorrow? Which is like; drive 15-20min easy accleration.. Stop, let cool down.. Repeat..

Only thing that sucks is like its an 45-hour back to my house.. So that might take a while. Should I replace the gear oil after the first 500 miles as well? The yukon gear instructions say too... but they are referring to vehicles that tow..
