Locking Hubs – Efficiency & Control for Part-Time 4WD
Locking Hubs allow you to engage or disengage the front wheel hubs from the axle shafts in part-time 4WD systems. Manual hubs give direct control, while automatic hubs engage when 4WD is selected. Choosing the right hub improves efficiency, reduces wear and keeps your drivetrain reliable for on- and off-road use.

Locking Hub Types
- Manual Hubs: Driver-operated dial for full control of engagement/disengagement.
- Automatic Hubs: Engage when 4WD is selected – convenient but less robust than manual.
- Fixed/Drive Flanges: Permanently locked hubs for maximum strength and simplicity.
Locking Hubs – Quick Comparison
| Type | Purpose | Key Benefits | Considerations |
|---|---|---|---|
| Manual | Direct user control | Strong, reliable, less wear | Must exit vehicle to engage |
| Automatic | Convenience | No need to leave cab | Less robust, harder to service |
| Fixed/Flanges | Permanently engaged | Ultimate strength, simplicity | Constant wear & fuel use |
How to Choose the Right Setup
- Driving mix: Touring and mixed road/off-road use usually favour manual hubs.
- Convenience: If you prefer not to exit the vehicle, automatic hubs add ease at the expense of strength.
- Strength: For competition or heavy rock work, fixed flanges provide maximum durability.
- Serviceability: Manual hubs are easier to maintain and rebuild than automatic hubs.
Example: For an expedition rig, fit manual locking hubs to reduce front driveline wear on highways and engage only when needed off-road.
Fitment & Compatibility Guide
- Axle spline count: Verify spline count matches hub model.
- Wheel offset: Ensure wheels clear hub dial or cap.
- Maintenance: Service bearings and grease hubs during installation.
- Water crossings: Manual hubs allow you to engage before entering water for consistent power delivery.
Upgrade Sequence Roadmap
| Stage | Focus Area | Why It Matters |
|---|---|---|
| 1 | Select Hub Type | Manual for control, auto for convenience, flanges for strength. |
| 2 | Service Bearings | Ensure wheel bearings are clean, greased and properly torqued. |
| 3 | Install Hubs | Follow torque settings and sealing procedures. |
| 4 | Test Operation | Confirm smooth engagement/disengagement before trail use. |

Frequently Asked Questions
- Do manual hubs improve fuel economy?
- Yes. Unlocking reduces drag from the front driveline, saving fuel and wear on long highway runs.
- Are automatic hubs reliable?
- They are convenient but less durable than manual hubs. Off-roaders often prefer manual for reliability.
- Do I need locking hubs on a full-time 4WD?
- No. Locking hubs are mainly for part-time 4WD systems; full-time 4WDs use constant engagement.
- Can I fit manual hubs in place of automatic hubs?
- Yes. Many kits allow direct conversion for added strength and control.
- Do you ship locking hubs across Europe?
- Yes. OFM4x4 supplies and ships manual and automatic hubs throughout the UK and Europe, with local stock options for faster delivery.
