If you’re looking to upgrade or replace the axle assembly in your Hummer H3, you might want to check out the Zumbrota Drivetrain Axle Assemblies. These aren’t just any remanufactured parts; they’re rebuilt with a level of precision and reliability that’s hard to find. I’ve had my hands on these assemblies, and you can really feel the quality in the details.

Each axle assembly goes through a rigorous inspection process. They check for straightness, cracks, and surface wear—no shortcuts here. All the internal components, like the ring and pinions, gears, clutches, and carriers, are thoroughly inspected and tested. It’s reassuring to know that every bearing and seal is replaced, so you’re getting a fresh start with your assembly.

What really stands out is the attention to the gear setup. They measure the rolling torque using inch-pound measurements, which ensures everything is set up just right for longevity. Plus, they make sure the gear backlash is spot on to keep things running smoothly and quietly. I’ve seen too many setups where this is overlooked, leading to all sorts of headaches down the line.

And if you’re worried about the condition of the axle tubes, rest easy. Zumbrota inspects them to make sure they meet OEM standards for straightness. You want your ride to be solid, and these guys get that.

They even go the extra mile with a hydro-blast rinse and sandblasting procedure, followed by a proprietary deep cleaning process. This means you’re not just getting a clean part; you’re getting something that looks and performs like new.

• Shipped in high-density plastic totes to avoid any damage during transit—because nobody wants a damaged part showing up at their door.
• Every housing undergoes testing for surface wear and cracks, so you know it’s going to hold up.
• They inspect 100% of the internal parts, including the ring and pinions, gears, clutches, and carriers.
• All bearings, seals, crush sleeves, pinion nuts, and shims are replaced, ensuring you’ve got everything you need.
• They clean the housings using a state-of-the-art hydro blasting process, bringing them back to that OEM finish.
• Correct rolling torque is established for precision setup and longevity—no guesswork here.
