If you're on the hunt for a solid axle assembly that won’t let you down, you might want to check out the Zumbrota Drivetrain Axle Assembly. These things are rebuilt with a focus on quality that’s hard to beat. Each assembly goes through a thorough inspection process, so you can trust that they’re straight and free from cracks or surface wear. It's not just a quick once-over, either; every internal component—think ring and pinions, internal gears, clutches, and carriers—is fully tested. They replace all the bearings and seals too, so you know you’re getting a fresh start.

Now, let’s talk about the gears. They’re not just thrown in there; they’re inspected for optimal tooth contact patterns and rolling torque using precise inch-pound measurements. This means that when you set it up, you’re going to get the longevity and performance you’re after. Plus, the correct gear backlash is set to keep everything lubricated and running quietly. The axle tubes? They’re checked to ensure they meet OEM straightness standards, so you can count on them to perform.

Zumbrota goes the extra mile with their cleaning process. They use a hydro-blast rinse and sandblasting on both the internal and external parts, followed by a proprietary deep cleaning method. This isn’t just about looks; it brings everything back to that OEM finish you want.
