Driveshaft Parts for Jeep CJ7
U-Joints, Propeller Shafts and Yokes for Reliable Power Transfer (1976–1986).
Why the Driveshaft in the Jeep CJ7 Needs Attention Over Time.
The driveshaft in the Jeep CJ7 transmits power from the transmission and transfer case to the front and rear axles while constantly compensating for the angle and length changes that occur as the suspension flexes and the vehicle steers. U-joints wear from constant rotation under load, lose grease or dry out, and then begin to clunk or vibrate. The propeller shaft itself can show up through imbalance, a bent tube, or worn slip yokes, especially after axle swaps or a suspension lift. Yokes at the transfer case and axle wear at the splines, while seals at the transmission output and differential harden and let oil escape. Anyone driving their CJ7 off-road, running larger tires, or running a suspension lift should regularly check the driveshaft for play, vibration and leaks to avoid follow-on damage to the transmission and axles.
- U-Joints & Straps: The greasable U-joint and the matching U-joint strap kit for secure mounting to the axle yoke.
- Propeller Shafts: The front propeller shaft for 2.5-liter models and the rear propeller shaft for SR4/T176/T177 transmissions.
- Yokes: The yoke kit for the Dana 300 transfer case and the pinion yoke for Dana 30/44 axles.
- Seals & Gaskets: The propeller shaft seal and the pinion seal at the differential keep the drivetrain sealed.
- Transfer Case Output & Hardware: The Dana 300 output shaft seal and the yoke nut complete the repair.
American Precision from Two Proven Brands.
U-joints, U-joint strap kits and yokes for the transfer case and axle come mostly from Dana Spicer – the original manufacturer behind the driveshaft components themselves – complemented by seals, yokes and the front propeller shaft from Crown Automotive, a hallmark of American engineering. The rear propeller shaft for SR4/T176/T177 transmissions comes from Omix – also standing for American-made quality.
