Well, this is the reason I started the LS swap in the first place. I initially had planned on keeping the original drivetrain and just bagging it and enjoying it ...But the rear end locked up one night and I just happened to have a few spare LS motors at the shop at the time.
Fast forward a year, and I'm finishing the Porterbuilt rear setup and finally decided to see what 12 bolt was in the truck and what was going on with it.
Found out someone swapped an HA 3.72 rear end in the truck, which made me extremely happy due to needing a 3.72/4.11 for the 4l80e.
Ring gears look great, I haven't removed the carrier yet, but I'm sure there's some damage on the pinion gears.
My question is, is the carrier salvageable? If so, I can just buy some 4.11 gears and swap them in with new bearings/crush sleeve etc..
