Instaled a Locked (clutchpack) AuburnGear diff this summer along with all new bearings, cups and seals
I kept the spindels the where fine.
I kept the 3.40 gears that i had, and had never heard of before (usualy GM is 3.42), the ring gear had a litle wear from used bearings but it doesnt make a peep. All in all with the diff, bearings, cups, seals, oil and gasket i spent apbout 700$
Here with the alignment paste, we can see the wear i was talking about (note the absence of paste on the bottom left side of the tooths.)
But everything works great!
