Dana 27 Front Axle & Differential Parts for Jeep CJ5
Axle Hubs, Seals, U-Joints & King Pin Bearings for Reliable Power Transfer (1966–1971).
Why the Dana 27 Front Axle in the Jeep CJ5 Needs Servicing After Decades.
The Dana 27 front axle replaced the weaker Dana 25 in the Jeep CJ5 starting in 1966 and remained in use until the end of the model run in 1971 – structurally tougher, but just as maintenance-prone after more than 50 years. The hub seal hardens over time and lets grease escape, causing wheel bearings to run dry and wear prematurely. U-joints wear from the constant load transfer with every steering input and develop noticeable play. King pin bearings and their cups wear from the pivoting motion during steering, leading to uneven rotation and increased tire wear. The pinion nut and its locking washer can also loosen over time from vibration, resulting in play in the drivetrain. Anyone driving their CJ5 off-road or preparing it for daily use should regularly check the Dana 27 components for play, leaks, and grease loss.
