Dana 18 Transfer Case Parts for Jeep CJ6
Gears, Seals and Shift Components at a Glance (1955–1971).
The Heart of Power Distribution in Your Jeep CJ6.
The Dana 18 transfer case is one of the most durable and widely used units in the Jeep CJ6, splitting engine power via the intermediate shaft and gears between the front and rear axles. After decades of use, typical wear patterns appear: the needle bearings on the intermediate shaft wear out, gears develop play and start whining, while seals and housing gaskets harden with age and begin to leak oil. The shift mechanism – shifter boot, poppet ball, and shift lever – wears down from frequent gear changes, leading to stiff or imprecise shifting. Pinion nuts and flanges can also loosen over time from vibration. Keeping your transfer case properly maintained protects both off-road capability and the longevity of the transmission and axles behind it.
- Intermediate Shaft & Needle Bearings: The complete intermediate shaft kit with all needle bearings, plus the individual needle roller bearing for the intermediate shaft.
- Gear & Output Bearing: The front output gear along with the matching front output bearing.
- Seals & Gaskets: The output seal and the cover gasket keep the transfer case reliably sealed.
- Shift Mechanism: The shifter boot and the matching shift knob for precise shifting.
- Driveline & Fasteners: The Dana 18 flange nut along with the propeller shaft slip yoke for the driveline connection.
- Repair Kit: The complete small parts repair kit for a full overhaul in a single job.
American Engineering for Your Transfer Case.
Most of the range – from the intermediate shaft to gears, seals, and shift components – comes from Crown Automotive, one of the best-known names in Jeep parts made in the USA. Flange nuts and lock washers come from Dana Spicer, the original manufacturer of the transfer case itself, while the propeller shaft slip yoke and cover plate gasket are supplied by Omix – both brands likewise rooted in the USA.
