Used Wheel Axle for Construction Equipment

The Role of the Wheel Axle in a Machine's Axle Assembly

The wheel axle fits internally into the planetaries of the differential and transfers torque to the wheel hub, often through a reducer. It rotates within the axle housing "trumpet", on a bearing, and is immersed in oil sealed by a gasket at the axle end. On a wheeled excavator or loaded dump truck, it handles both engine torque twist and part of the machine's weight. If the housing is cracked or the differential worn, consider our used axle assemblies.

Wheel Axles Dismantled by Equipment Type

• Articulated dump trucks Volvo A20 to A30 and Caterpillar 725 and 735B
• Wheeled excavators Liebherr A904 to A924, Caterpillar M313D and M320, Hitachi ZX140W
• Wheeled loaders Liebherr L524 to L576 and Volvo L120E, L180E
• Backhoe loaders Case 580 and Fermec 760, 860, Caterpillar TH330B telescopic models
• Mecalac machines 714MW, 12MTX, and 12MX

How to Identify the Correct Wheel Axle Before Ordering

Usually, three measurements suffice to distinguish between two similar axles. Count the number of splines on the differential side, and on the wheel side if the axle has splines there as well. Measure the length under the flange, from the flange face to the splined end. Finally, note the diameter at the bearing seat. Add the machine position—front or rear axle, left or right side—and the serial number: our advisors find the matching used wheel axle or a model with the same dimensions.

Signs That a Wheel Axle Needs Replacement

• Rounded or stepped splines: the wheel has play when starting.
• Twisted axle after an overload, visible by wobbling during rotation.
• Scratched bearing or seal seat causing oil leaks at the axle end.
• Clicking noises when turning or sounds increasing with speed.
• Clean break of the axle, often starting at the splines.

Used vs. Remanufactured Wheel Axles: What’s Different

For the most common dump trucks and loaders, remanufactured wheel axles are available. For less common wheeled excavators or older machines, new axles are often no longer listed in the manufacturer's catalog. A used axle removed from the same model retains the original spline count, length, and surface treatment: it fits perfectly into the planetaries and hub without modification. The inspection focuses on spline condition, absence of twist, and bearing and seal seats, which must remain smooth.

What to Expect When Replacing the Axle

• A new seal at the axle end: the old one almost always leaks after removal.
• The axle bearing, which should be inspected and often replaced simultaneously.
• Axle oil, to drain and refill with the grade recommended by the manufacturer.
• Inspection of the planetaries and reducer after a break, because steel debris can circulate in the oil.
• The hub, if its internal splines show wear at the same location as the axle.

Requesting a Wheel Axle from Our Advisors

Send the brand, model, and serial number of the machine, along with a photo of the dismantled axle and its measurements. Our advisors search among approximately 17,000 references of used spare parts and respond at 05 18 23 21 34. If you are replacing both sides of the same axle, please specify: they will preferentially look for a pair removed from the same machine with comparable wear. Other axle and drivetrain parts are grouped in our used construction transmission parts.
