Ok, i'm buying a slightly used Yukon front 4.88 ring and pinion with a pinion bearing already pressed on. The gears have about 1000 miles on them. I was wondering if i will need a master install kit, a mini install kit, or anything at all. If i get the master install kit what about the genuine gear master install kit. It's 98 from 4wheelparts right now. I've heard bad things about genuine gears but what about their install kits?

 

here's the install kit http://www.4wheelparts.com/4wp/produ...U&expand=sub10

 

anybody? just need a go for it, or dont go for it
