I know that...I'm just saying, your doing it just for the LS. okay. Seems foolish if you lifted your truck you gonna put bigger tires on it. Why not go all the way and get a better gear ratio now instead of not liking the way the truck drives once those tires are on? You see where I'm coming from? Get what I'm sayin'?
*btw...front axles are pretty plentiful and can be had for $100. I got my 30k used 4.10 one for 75. And if you can change out a rear axle, you can take out the front axle.
Like said above, pop the cover off and take a look at the condition of the gears, the spiders. Inspect every tooth for a chip or crack. Maybe pull the axle shafts too to inspect the splines and the center pin in the carrier. See how much backlash there is....hold the ring gear in place and rotate the pinion. should just be a tiny bit of slop. see how tight the LS is.....at 60-75k, the LS starts to show wear and stops acting like an LS and starts acting like an open. Have a buddy hold a wheel flange while you try to spin it. If it's hard and difficult to turn, good. Nice and tight LS. At only 60k, the only wear visible should be some LS wear.
I'll stop cluttering the thread now.
