...S-10 10-bolts with 4.56's? The RPO codes said this thing had 3.42's, but we suspected that it may have been modified, so we decided to double check the bad rear end before we got a replacement. The pinion used to have 9 teeth (now has 7) and the ring gear has 41, so 4.56 ratio. Check out this carnage! Random magnet found at bottom of case, full of shavings, and two pinion teeth. So how hard is it gonna be to find a replacement axle for this. I'm thinking that these axles can't be too common among S10 blazers, but I don't know.
