*I have searched and googled quite a bit and have only found bits and pieces of good information. Going to be finishing up this install this week and just want to make sure I got it right. This is my first gear install. For reference, these are G2 gears in the 4.56 flavor and a new carrier.
OK, Got some questions/confirm my plans for those guys that have installed new gears in their later model high pinion dana 30. Here's where I'm at:
-Diff is empty
-new carrier is assembled
-have master install kit(that doesn't come with either oil slinger or baffle-bought separately).
-Have everything organized and ready to go.
I am currently at getting the new pinion set up to be put in to check pinion depth. I am not reusing the stock inner(next to head) oil slinger as I have read it is too thick (.060). I have a new Yukon slinger coming in at .033 and the baffle that I managed to not beat up taking it out comes in around .020. From what I've read around, the starting point that most people are looking for is .057(total) which includes the oil slinger, the baffle that is between the race and the housing, and the shim that you add to get to .057.
I have made set up bearings(and inner pinion race) for everything. I am assuming I should try the original shim stack size on the opposite(yoke) end under the outer bearing with a set up bearing to be able to check for backlash, and adjust the inner(head) shim size if needed. Once I get the backlash set, I check for pinion preload(or do i set this first?) and get that set. Then Its on to the carrier preload and I've read that adding .002-.003 usually does the trick(after initially checking backlash with just enough shim that there is no side-side movement of the carrier(snug fit). And I know the process for checking carrier preload.
And that should be it right? Or am I forgetting something?
