Dana 20 Transfer Case Parts for Jeep CJ5
Shafts, Bearings, Seals & Small Parts for Your Transfer Case (1972-1979).
Why the Dana 20 Transfer Case in the Jeep CJ5 Wears Out Over the Years.
The Dana 20 transfer case was fitted to the Jeep CJ5 from 1972 to 1979, before being replaced by the stronger Dana 300. As the link between transmission and both axles, it transfers full engine power to the front and rear axle and faces extreme stress during off-road use. Over the years, the intermediate shaft's gears and bearings wear from constant power transfer, while seals and housing gaskets harden and start leaking gear oil. The shifter boot cracks from UV exposure and vibration, shift springs fatigue, and the gaskets connecting to the transmission lose their sealing tension. Anyone who regularly checks their transfer case for oil level, noise, and leaks prevents follow-on damage to axles and driveshafts and keeps their CJ5's off-road capability intact long-term.
- Intermediate Shaft & Gears: The intermediate shaft and the intermediate gear form the heart of power transfer.
- Bearings & Thrust Parts: The output shaft bearing cup and the main shaft bearing keep the output shaft running true.
- Seals & Gaskets: The complete gasket kit and the output oil seal reliably prevent oil loss.
- Shifter & Small Parts: The shifter boot and the small parts repair kit refresh the complete shift linkage.
- Yoke & Driveline Connection: The propeller shaft yoke and the transmission torque arm bushing cleanly connect the transfer case to driveshaft and frame.
American Precision Parts for Your Transfer Case.
Intermediate shafts, gears, bearings, gasket kits and shifter components come almost entirely from Crown Automotive – the specialist for Jeep drivetrain parts with an American manufacturing heritage. Yoke hardware such as lock washers and pinion nuts is supplied by Dana Spicer, the original manufacturer of the Dana 20 itself. The transmission mount bushing comes from Daystar, also US-made.
