If you're on the hunt for a solid replacement for your Ford F-150's rear axle, look no further than the Zumbrota Drivetrain Axle Assembly. These aren't just any remanufactured axles; they're rebuilt with a level of care and precision that you can really appreciate. Each assembly goes through a rigorous inspection process to ensure everything is up to snuff—think straightness checks, crack inspections, and surface wear evaluations. It’s like giving your truck a new lease on life.

What’s more, every internal component is thoroughly checked and tested. We're talking about the ring and pinions, internal gears, clutches, and carriers all getting the once-over. And yes, all bearings and seals are swapped out to keep things fresh. You want an axle that’s going to last, right? Well, Zumbrota makes sure the gears are inspected for optimal tooth contact patterns and set up with precise rolling torque measurements. This attention to detail helps ensure longevity and smooth operation—no one wants to hear that grinding noise when they hit the gas.

And let’s not forget about the axle tubes; they’re inspected to meet OEM straightness standards. Zumbrota takes it a step further with their unique hydro-blast rinse and sandblasting process for cleaning both the internal and external parts. This means you’re getting an axle assembly that not only performs well but looks good too, as close to OEM as you can get.
