Good info to know...

So no backlash adjustment should be needed? I've never torn into the rear diffs on these. Always have wanted to upgrade to an Auburn LSD.

if someone could pm me what info u need i can give that info to u, thanks any help will be much app.
Count the number of bolts you have on the back cover... 10 = 8.25, 12 = 9.25


You'd be looking for 4.10 gears or 3.92 for an upgrade from the 3.55s

Default Spider gear replacement on LSD rear end

I need to have my spider gears in my 2008 Dodge Dakota, replaced. 9.25, 3.55. I was told by one shop it can be done, another shop said I would have to replace the whole carrier. He said the spider gears can not be replaced independently. Any help?

Thanks

Rick
