well the gears and diff were replaced about 4000kms ago. I don't know much of the details. The gears were used 3.73 (low kms) and looked like new. The diff was new, got a deal because the guy had had it in his shop for a while (still in box). I don't know anything about what type it is. All I do know is that the splines were different from what were on my stock axles. So that had to change the inputs on the diff. The guy that rebuilt it over did the crush sleeve(?) so it didn't take long before the rear started making noise. So the car got parked. Then when I finally got it fixed, I had the another set of new bearings, new stock replacement axles, new studs, and new seals. He said there was a bit of wear on the gears. But that it was nothing that would affect the rear end. At the worst he said it might make a bit of noise when decelerating (which it doesn't). I also added a LPW cover to it too. Along with Edelbrock Anti-hop bars, double adjustable uppers, and boxed lowers. Since the last rebuild, (about a year ago) it has been behind a bone stock 305/TH350 (no shift kit) with 196/60/15s. So it hasn't been abused by a powerhouse engine. And because my tires (that I also bought at the same time I had the rear done) were over $700, I have only done maybe 4 or 5 small burnouts. And with the rear suspension, those were 'wheel-hop free' burnouts lol.
