Used Tractor Wheel Axle Shaft

Role of the Wheel Axle Shaft in the Front Axle

The wheel axle shaft transmits torque from the differential to the hub. On a four-wheel drive tractor, it starts from the bevel gear, passes through the front axle housing, then the kingpin, where a double universal joint allows it to follow steering movements. On a non-driven front axle, there is no wheel axle shaft: only the spindle carries the hub. The wheel axle shaft then drives the wheel reducer, which multiplies the movement. Its length, splines, and joint type are specific to each axle: therefore, a wheel axle shaft should be chosen based on the axle reference, not just the machine model. On a combine harvester, the front axle is the driven axle: the wheel axle shaft connects the differential to the final reducer, with no steering articulation since the rear wheels handle steering. The force transmitted is significant during peak harvest, causing wear on splines and support bearings.

What Are the Symptoms of a Damaged Drive Shaft?

On a front axle, the wheel axle shaft or its joint is most often the culprit. The most common sign is a regular knocking noise when steering with the front axle engaged, indicating play in the double universal joint. A vibration increasing with speed, jerks on acceleration, or a leak at the kingpin seal should also raise concern. A shaft break results in a front wheel no longer driving while the axle continues to turn. Have a diagnosis made before ordering: a worn hub bearing or kingpin can sometimes produce similar noises. A torn boot or seal also lets dirt into the joint; replacing it early often prevents the need to replace the entire shaft.

Information to Note Before Ordering

• The brand, model, and serial number of the tractor or combine harvester.
• The brand and front axle reference, stamped on the plate or housing.
• The side concerned, left or right, and the length of the removed shaft.
• The number of splines at each end and the type of joint.
• Some photos of the part and surrounding area.
• The number of teeth on the bevel gear if the axle has been opened.

Used Tractor Parts: The TMC Bejenne Approach

Since 1945, TMC Bejenne has dismantled agricultural machinery of all brands on its 11-hectare site in Naintré. Each wheel axle shaft is dismantled, cleaned, and inspected: checking straightness, spline condition, play in cross joints and bearing supports. Our stock of 25,000 references also covers adjacent axle parts, from the subframe to the transfer case. Our specialized technicians confirm compatibility before each shipment.
