If you’re in the market for a reliable axle assembly, let me tell you about the Zumbrota Drivetrain Axle Assemblies. These aren’t just your run-of-the-mill rebuilds; they’re crafted with a level of precision that really stands out. I’ve had my hands on a few of these assemblies, and it’s clear that Zumbrota doesn’t cut corners. Each assembly goes through a rigorous inspection process. They check for straightness, cracks, and any surface wear that could cause issues down the line. It’s like they’re giving each axle a thorough health check before it even hits the road.

What’s really impressive is how they handle the internal components. Every single part—think ring and pinions, internal gears, clutches, and carriers—is inspected and tested. They don’t just throw new bearings and seals in there; they replace everything that needs it, ensuring you get a fresh start without any hidden surprises. Plus, they pay close attention to the gear setup. They use inch-pound measurements to get the rolling torque just right, which is crucial for longevity and performance. And let’s not forget about gear backlash; they set it correctly to keep everything lubricated and running quietly. It’s the little things that make a big difference.

Now, let’s talk about the cleaning process. Zumbrota employs a unique hydro-blast rinse and sandblasting procedure that really gets into every nook and cranny. This isn’t just for show; it brings the housing back to an OEM finish, making sure it looks as good as it performs. You can feel confident knowing that these assemblies are built to last.
