New Guy Hoping for Information

I just bought a 1996 Trooper. The rear differential is howling. I discovered it has water in it. The ring/pinion are obviously shot. Id like to look for a used pumpkin (is that term still used?) before I remove the old one that's still working. Does this plate tell me what the ratio is and and if it has positraction? How do I decode this? Is there another way to get the specs on this vehicle?

****, I apologize. Not sure where my scatter brain picked that information up from.

Let me correct myself. The Isuzu 12 bolt you have is stronger than a dana 44. And with the G80 option code (which unfortunately yours doesn't have, but is easy to find at a junkyard) you can get a clutch-pack limited slip. A great little upgrade over your stock open diff.

You'll want 88-97

Here's a link with some more info, see Isuzu Corp 12-bolt (rear)


edit: and here's a link to the option code list (5th post). Your code HC6 denotes the 4.56 gear ratio
