Overview
The G2 Axle and Gear CORE 44 front axle assembly with a 5.13 ratio and an Auburn Ected locker (part C4TSFS513MC0) is for 1997–2006 Jeep Wrangler TJ and LJ models and 1984–2001 Jeep Cherokee XJ models. The axle uses an Auburn Ected locker, and the 5.13 ratio is set for that locker.
The housing uses a new design with a high pinion Dana 44 gear layout, built to carry heavy loads that would bend a stock Dana 30 or Rubicon Dana 44. It takes stock Dana 44 ring and pinions, axle shafts and aftermarket lockers, and it reuses the factory brakes.
Key features
- High pinion Dana 44 gear layout in a new housing
- Auburn Ected locker
- Accepts stock Dana 44 ring and pinions, axle shafts and aftermarket lockers
- 30-spline axle spline
- Designed for heavy loads, per G2
- Reuses factory brakes
Living with a locker axle
A locker changes how the axle behaves. With an Auburn Ected locker, both wheels turn together when one side loses grip, which helps on rocks, mud and loose ground. On dry pavement the same lock can push the vehicle straight through turns, so it is worth getting used to the feel in a parking lot before driving on the road.
Because the ring and pinion carries the load, it is the first part to show wear. Watch for oil seepage at the axle seals, metal flakes in the gear oil, and a whine or clunk that changes with speed or throttle. Any of these signs means the axle should be inspected before it sees more use.
- Inspect the axle seals after each hard trail day
- Check the locker engages cleanly before each trip
- Re-check cover bolts after the first few trail runs
