Ok... some background info first, my truck has the 8.8 28 spline open differential with 4.10 gears. I am buying a LS differential (pics below), with the oem pin, and an unused shim pack that came with a locker. Exactly what else will I need to install this on my truck using my existing 4.10 gears?

 

shouldn't need anything since you are using the same gear ratio w/ the LS carrier....should be able to take your carrier out and use the shims off it to install the L/S carrier....just make sure you remember which side the shims came off of so they can go back on that side.....

 

addtive, oil, bearings I THINK..gasket maker stuff to put the cover back on..um...i think that would be it

 

^^^^oooo yea i forgot about that! lol....that is the most important stuff!

 

your going to need a press or just get new bearings for the carrier...

also will need to check your backlash and all that... wouldnt be any different then installing a new Ring and Pinion.

i would recommend getting some help from someone that has setup a 8.8 before.

 

My uncle is a mechanic, I plan on taking it to his garage and him helping me, I'm not sure if he has setup an 8.8 but I know he has done gears and rear ends before.

 

do you have to recheck it even if you install the same gears?

 

yes since its comin off and your reinstallin it on a new carrier unit..better be safe then sorry

 

I want to get everything before I get my LS so I will be good to go. So far my list contains this:
- new carrier side bearings and races
- gasket maker stuff (do you recommend this over an OEM gasket?)
- LS additive (what brand do you all recommend?)
- differential fluid (same ?, what brand?)

 

might wanna add a can of brake cleaner so just spray on the stuff to get it nice and clean..

 

i would certainly think so. what if the carrier is different? moves the ring gear...

 

get a synthetic fluid like lucas or amsoil so you dont need that silly additive.
