Identifying Differential Types:

1. Open Differential (Open Diff):
   • Allows wheels to spin independently; most common in stock vehicles.
2. Limited Slip Differential (LSD):
   • Provides some traction improvement, transferring power to the wheel with more traction when slip occurs.
3. Locker (Locking Differential):
   • Locks both wheels together, providing equal power to each wheel; enhances off-road capability but affects maneuverability on-road.
4. Electronic Locker (eLocker):
   • Can be electronically engaged or disengaged, offering both off-road prowess and on-road maneuverability.

Remember, this chart provides a general overview. For precise identification, consult your vehicle’s manual, or if you’re uncertain, it’s always best to seek help from a professional mechanic or a Jeep specialist.
