Got pitting on the bearing surface of the axle, my mind says replace the axle, my wallet says it's fine run it till it causes another problem. I already replaced the bearings and seals.

I've used many "axle repair bearings" before, it's a unitized bearing and seal whose bearings ride on a different part of the axle. Don't know if they make them for an 8.8 but I know across all the brands ( 1/2 ton truck and lower, cars included in that). There's only a few bearing and seal numbers that seem to fit (most) all of them with c clips. Ford Mopar or GM. Look at year make and model of several brands and the book will come up with the same numbers for many

look into a "package bearing" (as volare don was talking about upthread)

here's a link, though they're out of stock.



ETA: found it, mevotech HRP6408 or schaeffler 102549

yeah, causes another problem like eating up the bearing and having that come apart and wreck the housing or put enough shimmy shake to gut out the diff, or worst case lose a wheel.

that's done weebled all its wobbles out hombre. replace.

Ha, guess I'll be replacing the carrier bearings too as they look the same. The rear sat for 20 years, the bearings and races started rusting where they were contacting each other

The good thing about an 8.8 is a rebuild kit are pretty cheap!

When I shortened mine and was looking at replacing all the other components, the kit I got from Yukon Bearings said it was for a 12 bolt Chevy, I was like, great they’ve sent me the wrong crap! Doubled checked number, sure enough, they were correct!
 
Yup a lot of them take the same bearings.
I've rebuilt several of them, never had to replace a ring and pinion though. I just save any and all shims that were in it originally and put them back as they were
 
I would replace it, especially if your pushing some power or launching with sticky tires.
Agree.
Swapped to an 8.8 cause 8 3/4 prices are nuts? Run it.
Swapped to an 8.8 to last behind 500 hp, stick shift, and slicks? Time for a set of good axles

Edit: just saw long road trips. Replace.
