Overhauling an Off-Road Legend: Premium Overhaul Solutions for Your Jeep CJ3A Dana 44 Rear Axle.
The architecture of the Dana 44 rear solid axle on the 1949–1953 Jeep CJ3A established a heavy-duty benchmark for drivetrain resilience that still echoes through modern 4x4 engineering. Transitioned into service to handle intense civilian workloads and industrial agricultural applications, this tapered-shaft configuration demands precise mechanical care today. Decades of farm abuse, storage, or extreme climate cycles cause pinion bearings to growl and outer seals to weep, which quickly saturates your brake shoes. Our specialized online inventory features professional-grade replacement components to successfully restore your rear differential's mechanical integrity back to showroom standards.
Authentic Drivetrain Engineering: Dana Spicer, Omix & Crown Excellence.
For internal mechanical restorations of the gear carrier assembly, we rely on the precision components from
Omix to supply high-durability ring & pinion sets. Overhaul your input gear shaft smoothly using a premium
inner and outer pinion bearing set from Spicer to secure original backlash tolerances and eliminate drivetrain noise. Protect your lubricant circuit from environmental contamination with a factory-spec
differential cover gasket, pinion seals, and outer wheel bearing oil seals with gaskets from Crown Automotive. To ensure smooth mechanical alignment, upgrade your hubs with Crown wheel bearings with cups and specific transfer-case-to-axle needle bearings. Complete your assembly with replacement axle shaft nuts, genuine
Spicer output yoke nuts, and matching heavy-duty yoke flat washers to withstand severe vibrational stress.
