Driveshaft Parts for Jeep CJ6
U-Joints, Yokes & Slip Yokes at a Glance (1955-1975).
Why the Driveshaft in the Jeep CJ6 Needs Attention After Decades.
The driveshaft in the CJ6 transfers power from the transfer case through the propeller shaft to the front and rear axles, and has to compensate for length changes during suspension travel as well as changing drive angles. The U-joints at both ends of the shaft carry constant load and wear from moisture and insufficient greasing – noticeable play, driveline vibration, or a rhythmic clunk when pulling away are typical signs. The slip yoke compensates for length change and can start to bind if it runs dry, while flange nuts and lock washers can work loose from vibration over the years. Anyone restoring a CJ6 chassis or driving it off-road should check the entire driveshaft regularly for play at the U-joints and a secure fit at the flange connections.
- U-Joints & Slip Yokes: The greasable U-joint and the propeller shaft slip yoke for length compensation.
- Propeller Shaft Yokes: The Dana 30/44 propeller shaft yoke and the propeller shaft yoke with U-bolt mount for the axle connection.
- Nuts & Lock Washers: The pinion flange nut, the matching lock washer, and the Dana 18 transfer case shaft nut.

- Speedometer & Transfer Case Output: The 26-tooth speedometer gear and the transfer case output seal for the Dana 18/20 transfer case.
American Brand Quality for Your Driveshaft.
U-joints, propeller shaft yokes, the pinion flange nut, and the lock washer come from Dana Spicer, the original manufacturer of driveshaft components. Crown Automotive supplies the propeller shaft yoke with U-bolt mount, the pinion seal, the transfer case output seal, and the transfer case shaft nut, while the slip yoke comes from Omix. All three brands bring American engineering straight from the drivetrain's country of origin.
