[POWERSTROKE]

Since we're talking full floating rear axles, 25 years ago now I was fretting over getting a half or 3/4 ton truck. And I'm not sure why but almost 25 years later and 320,000 miles later it still has the factory installed bearings and seals. Guess I made the right choice all those years ago.
Never stops amazing me how these GMC trucks were built! Not many common parts with a Chevy, but I bet it's almost easier to get the GMC parts today than the Chevy parts.
