Overview
The G2 Axle and Gear CORE 44 front axle assembly with a 5.13 ratio and ARB Air Locker (part C4TSFS513AC0) is a Dana 44 front axle for 1997–2006 Jeep Wrangler TJ and LJ models and 1984–2001 Jeep Cherokee XJ models. The 5.13 ratio is paired with an ARB Air Locker, and the factory brakes are reused.
The housing is a new design built on a high pinion Dana 44 layout, meant for loads that could bend a stock Dana 30 or Rubicon Dana 44. Stock Dana 44 ring and pinions, axle shafts and aftermarket lockers all fit, which leaves room to choose the internals.
Key features
- High pinion Dana 44 gear layout in a new housing
- Built for heavy loads, per G2
- Accepts stock Dana 44 ring and pinions, axle shafts and aftermarket lockers
- ARB Air Locker
- 30-spline axle spline
- Reuses factory brakes
Locker use and axle wear
Lockers suit trail driving and steep grades where one wheel can spin on loose ground. On pavement, many owners run the locker open or use it sparingly, since a locked front axle can tighten during turns. Knowing when the locker is engaged helps reduce tire scrub and keeps the drivetrain in better shape.
Signs of a worn front axle include whining under load, clunking when the locker engages, grease or oil at the axle seals and vibration at speed. A 5.13 ratio puts heavy torque on the ring and pinion, so look for chipped teeth or fine metal in the gear oil at each service. Stock Dana 44 shafts and bearings are common replacements when the front end is serviced.
- Test the locker on a low-traction surface before a trip
- Keep the front differential breather clear
- Replace seals that have started to weep
