Dana 25 Front Axle & Differential Parts for Willys CJ3B
Axle Shafts, Wheel Hubs, U-Joints, Shims & Seals for Reliable Power Transfer (1953–1964).
Why the Dana 25 Front Axle in the Willys CJ3B Wears Out Over the Years.
The Dana 25 front axle is the heart of the Willys CJ3B drivetrain, absorbing steering, drive, and off-road forces on every trip. Axle shafts and U-joints face constant torsional stress and wear down over time, while wheel bearings develop play from moisture and lost lubrication. Seals at the axle shaft, pinion input, and differential cover harden and start leaking, letting axle oil escape and starving the whole axle of lubrication. Kingpins and their bearing cups are critical for steering – wear here causes play and imprecise handling. Wheel studs, hubs, and locking hubs also suffer after decades of use, especially on classic vehicles driven off-road more often. Anyone who wants to keep their historic vehicle roadworthy and safe should regularly check these components.
- Axle Shafts & Wheel Hubs: The axle shaft transfers drive power to the wheel, while matching wheel hubs and wheel studs keep the wheels securely mounted.
- Wheel Bearings & Pinion Bearings: Complete wheel bearing sets and the pinion bearing set keep the axle tight and load-bearing.
- U-Joints & Driveshaft: The axle shaft U-joint and the greaseable driveshaft U-joint transfer power smoothly to the wheels.
- Seals: The axle shaft seal, the pinion seal, and the differential cover gasket keep axle oil reliably contained.
- Kingpin Components: Kingpin housings, kingpin bearings, and the complete kingpin seal master set ensure precise steering.
- Locking Hubs: The locking hub set disconnects the wheels from the drivetrain when needed, saving wear in two-wheel drive.
American Engineering for the Dana 25 Front Axle.
Axle shafts, wheel bearings, U-joints, and kingpin components mostly come from Crown Automotive and Dana Spicer – both names with a long American tradition in axle manufacturing. Wheel hubs, kingpin housings, and the driveshaft slip yoke come from Omix, also a US manufacturer. All three brands deliver precise reproduction quality to original specifications.
