Frequently Asked Questions
Which John Deere wheel loaders do these front and rear axle assemblies fit?
Broken Tractor carries rebuilt front and rear axle assemblies for John Deere 644H, 644J, 644K, and 724J wheel loaders. The correct assembly depends on your model and serial number, so match the part number to your machine before ordering. Our parts team can help confirm fitment if you are unsure.
Does the rebuilt rear axle for the 644J fit all serial numbers?
No, the early rebuilt rear axle assembly (SKU RE160304) fits the 644J only below serial number 611231, along with the 644H and 724J. If your 644J is at or above that serial break, you will need a different configuration. Confirm your serial number before ordering so you get the right unit.
Is the John Deere 644K axle the same as the 644H or 644J axle?
No, the 644K uses its own rear and front axle assemblies (SKU JD-644K-RE and SKU JD-644K-FE) that are separate from the 644H, 644J, and 724J units. Order the K series parts specifically for a 644K loader. Matching the part number to your model ensures correct fitment.
What is included in a rebuilt axle assembly for a John Deere wheel loader?
Our complete rebuilt axle assemblies include the axle housing, differential, and drive components as a unit ready for installation. This covers both front and rear axle options depending on the model. Each rebuilt unit is tested for reliable field service.
Should I rebuild my John Deere loader axle or replace it with a rebuilt assembly?
A complete rebuilt assembly can save downtime compared to tearing down and repairing your existing axle, since it arrives ready for installation with the housing, differential, and drive components already serviced. Broken Tractor offers rebuilt front and rear axles for the 644H, 644J, 644K, and 724J. For help choosing the right unit for your serial number, call (800) 909-7060.
