65 c10 rear axle

[WOLFMANmike]

ok so i know we have a drive train section on here and just so you know i did post in it this but i got no answers . so now im asking here ..

so i bought this new to me 65 c10 12 bolt rear end the guy says that he has built many of them for other shops here in my neck of the woods . i called those shops and they all had good things to say . so i bought it far a sweet deal $ 600 . its a 3.73 gearing ... here is what he did completely took it apart checked all parts for damage including excessive heat replaced all seals and bearings and new crush sleeve . he said gear set looked great no bad or off pattern wearing so the gear set was not replaced . but was re set all over again and re checked for proper wear on all gears ring and pinion and spiders ... so that is the history for you now on this new axle ... but what i want to know and forgot to ask him is . is there a break in process for me to fallow ? kinda like breaking in a engine ? or do i not have one because my gear set is used ? and also because shes my daily driver and i dont use her to tow . is there a different break in for just a driver vs a towing machine ? obviously because its only a $ 600 axle and not a $ 1200 in a shop axle i dont get some great warranty . so i wanna make sure that if i am needing to do anything that i do it so i can ensure a long lasting rear end ... thanks for all your help in advance ....
