If it ain't broke, don't fix it.
If it is broke, just don't put another G80 back in it! They're not a great design in any sense of the word. For most people who daily drive these trucks and don't beat on them they'll hold up just fine, though. If you want a real locker I'd look into Eaton Detroit Lockers. Pricey, but you get what you pay for.
