Once removed, clean the spindle thoroughly to ensure a clean mounting surface for the new manual hub.
Now, take the flange and bolt it onto the hub, then replace the locking part. Install the spacer ring (if applicable for your manual hubs) all the way into place. Align the manual hub assembly with the spindle and carefully slide it onto the spindle shaft. Secure the hub using the provided bolts, tightening them in a star pattern to ensure even distribution of pressure. Torque the bolts to the manufacturer’s specifications using a torque wrench. Finally, reinstall the wheel and repeat the process on the other side. After the installation is complete, test the manual hubs by engaging and disengaging them in a safe area before hitting the trails.
Common Installation Issues and Solutions
Installing manual locking hubs on your GU Patrol isn’t always smooth sailing. A frequent issue is difficulty removing the auto hubs, often due to corrosion or the factory-applied Loctite. Applying heat or using penetrating oil can help loosen stubborn bolts. Ensure you have the correct spline count (usually 31 spline) for your vehicle model to avoid fitment problems. Another common problem is difficulty getting the hub to fully seat on the spindle. Double-check that the spacer ring is correctly installed and that no debris is obstructing the hub.
Sometimes, a brass bush may be incorrectly positioned, preventing proper hub engagement. Ensure it is oriented correctly. If the bolts provided with the manual hubs are too short, acquire longer, high-grade bolts. If you experience leaks after installation, inspect the gaskets and sealing surfaces for damage or improper alignment. Tighten bolts to the specified torque to prevent leaks and ensure proper hub function. Always test the hubs after installation to verify engagement and disengagement.
Locktite Usage Recommendations
When installing manual locking hubs on your GU Patrol, Loctite can be a valuable ally in ensuring a secure and reliable connection. However, it’s essential to use it judiciously. For the bolts securing the hub assembly to the wheel hub, a medium-strength (blue) Loctite is generally recommended. This provides a strong hold while still allowing for future removal if necessary. Avoid using high-strength (red) Loctite on these bolts, as it can make disassembly extremely difficult.
Clean the threads of both the bolts and the hub assembly with a wire brush and solvent before applying Loctite. Apply a small drop of Loctite to the first few threads of each bolt. Do not over-apply. Excess Loctite can seep into the hub mechanism and cause issues. After tightening the bolts to the manufacturer’s specified torque, allow the Loctite to cure fully, usually around 24 hours, before engaging the hubs or putting the vehicle under heavy load. Regularly inspect the bolts for looseness and reapply Loctite if needed.
