Description

Zumbrota Drivetrain remanufactured axle assembles offer reliable performance at a value price. They're available for thousands of applications—from passenger and off-road vehicles, to race cars and pulling trucks. The axle tubes are straightened to OE specifications; the housings are hydro-blasted and rinsed, then tested for surface wear and cracks; and the gear patterns and rolling torque are properly adjusted to ensure optimum tooth contact. Zumbrota replaces all seals, bearings, crush sleeves, pinion nuts, and shims on the front and/or rear axle assemblies. Order the replacement model recommended for your specific vehicle.
