Zumbrota Drivetrain Reman Complete Axle Assembly 8.8" Ring Gear Ford Explorer 2003-2005 4.11 Posi LSD - RAA435-2211B-P

When it comes to axles, you want something that can take a beating and keep on rolling. That's where the Zumbrota Drivetrain Axle Assembly comes into play. These guys know their stuff, and every axle assembly is rebuilt with a focus on precision and reliability. It's not just a quick fix; it's a thorough process that ensures you're getting a solid product.

Each assembly goes through a rigorous inspection. We're talking about checking for straightness, cracks, and surface wear. If there’s any sign of trouble, it gets addressed. All the internal components, like the ring & pinions, internal gears, clutches, and carriers, are fully inspected and tested. Plus, they replace all bearings and seals, so you know everything is fresh and ready to go.

What’s cool is that they don’t just slap it together and call it a day. They pay attention to the details. The gears are inspected for optimal tooth contact patterns and rolling torque is measured using inch-pound measurements. That means when it’s set up, it’s going to last. They also set the gear backlash just right to ensure proper lubrication and quiet operation. No one wants a noisy ride, right?

And if you’re worried about the axle tubes, don’t be. They’re inspected to meet OEM standards for straightness—no bending or warping here. Zumbrota even uses a special hydro-blast rinse and sandblasting process on both internal and external parts. This isn’t just cleaning; it’s about bringing everything back to that OEM finish you can trust.

Features:

  • All tubes are straightened to OEM specs, so you know they’re right.
  • Housings are tested for wear and cracks—no surprises down the road.
  • Every internal part gets a 100% inspection, from ring & pinions to clutches and carriers.
  • All bearings, seals, crush sleeves, pinion nuts, and shims are replaced—fresh is best.
  • Housings are cleaned using a state-of-the-art hydro blasting and rinsing process, restoring that OEM look.
  • Rolling torque is established with precision, ensuring longevity.
