To engage an air locker, first turn on the compressor, then press the air locker switch. This process is consistent across various brands like ARB, although specific switch locations and compressor controls will vary depending on the vehicle and installation.
Understanding Air Lockers and Engagement
Air lockers are differential lockers that use compressed air to lock the two axle shafts together, forcing them to turn at the same speed. This is crucial for improved traction in off-road conditions, especially when one wheel loses traction. The process is generally simple, but ensuring proper operation requires attention to a few key factors:
-
Compressor Pressure: Sufficient air pressure is vital for successful engagement. While some lockers may engage at lower pressures (e.g., 50 psi), maintaining higher pressure is recommended for reliable performance. Many systems will automatically engage the compressor while the locker is active, maintaining pressure. However, some systems require the compressor to remain active until engagement is complete.
-
Wheel Speed: Ideally, both wheels should be rotating at roughly the same speed when you engage the locker. Engaging a locker when one wheel is stationary or spinning significantly faster can lead to component damage (the “crash locking” effect mentioned in some references). While some systems can handle slight speed differences, matching wheel speeds as closely as possible is best practice.
-
Post-Engagement Confirmation: After engaging the locker, confirm its function. Manually checking wheel rotation (after jacking the vehicle to lift the affected wheel) or observing the vehicle's behavior during low-traction maneuvers can verify if the locker is properly engaged.
Troubleshooting Air Locker Engagement Issues
If the air locker fails to engage, consider these possibilities:
- Insufficient Air Pressure: Verify your compressor is functioning and that the air lines are free of leaks.
- Faulty Solenoid or Switch: Examine the electrical components for malfunctions.
- Air Line Issues: Ensure the air lines are properly connected and not obstructed.
- Internal Mechanical Problems: This requires professional diagnosis and may indicate more serious mechanical issues.
Remember to consult your vehicle's owner's manual and the specific instructions for your air locker system for detailed operation and troubleshooting guidelines. Various forums (like those cited above) offer user experiences and potential solutions to specific problems.
