Overview
The CORE 44 front axle assembly with a 4.56 ratio and ARB Air Locker, part C4TSFS456AC0, is a Dana 44 front axle for the 1997–2006 Jeep Wrangler TJ and LJ and the 1984–2001 Jeep Cherokee XJ. The high pinion Dana 44 gear design sits in a new housing, and it is a direct fit that reuses the factory brakes.
The housing is a whole new design built to take heavy loads that would bend a stock Dana 30 or Rubicon Dana 44. It accepts stock Dana 44 ring and pinions, axle shafts and aftermarket lockers, so the internals can come from Dana 44 parts already in use.

- Accepts stock Dana 44 ring and pinions, axle shafts and aftermarket lockers

Building a Dana 44 front
A Dana 44 front is usually built around the gear set, the locker and the axle shafts, so the parts should be chosen together. A 4.56 ratio changes the engine’s effective gearing, which affects tire size and top speed, so tire diameter should be considered before the gears are set. Lockers add traction at the cost of some on-road manners, and many owners set them up with the axle shafts and hubs in mind.
The gear set and locker need careful setup and break-in, and the carrier bearings and pinion preload should be checked before the axle is put into service. A housing with a high pinion gear can change driveshaft angles, so the driveshaft and transfer case output should be inspected after installation. Keep the differential oil clean and use the lubricant type the gear set requires, and check the axle seals regularly during off-road use.
- Set pinion preload with the gear set
- Check driveshaft angles after installation
- Inspect axle seals after each off-road trip
