Don’t Force It

If a part doesn’t fit easily, don’t force it! Check that you have the correct part and that everything is aligned correctly. If something doesn't seem right, stop and re-evaluate. Forcing components can damage them. This can also lead to more problems down the road. If the parts are not fitting easily, it often indicates an underlying issue that needs to be addressed.

Troubleshooting Common Problems

Even with the best preparation, you might run into some snags. Here's a look at common issues and how to resolve them.

Leaking Grease

If you see grease leaking, it’s likely that the seals aren't seated correctly or are damaged. Double-check the seal installation. Make sure you use the correct seal for your Nissan Patrol model. Inspect the seal surface for any imperfections. Ensure that the hub is not damaged, as this can prevent the seal from sealing properly. If the seals are fine, you might have over-greased the hub, creating too much pressure. Be cautious about the amount of grease used, as it can cause the seals to fail if excessive.

Steering Issues

If the steering is still stiff after the rebuild, check the swivel hub bearings. Make sure they are correctly installed and properly greased. Inspect the steering components for any damage. Check the tie rod ends and ball joints. Ensure the steering linkage is properly aligned and lubricated. This may be an indication of other problems, like a faulty steering box.

Noise and Clunking

If you hear noises, such as clunking, after the rebuild, it's possible that the bearings are not seated correctly. Recheck the bearing installation and ensure that everything is tight. Listen closely to identify the source of the noise. Check the locking hubs, if equipped. They may need further inspection and possible repair. Ensure that all bolts and components are tightened to the correct specifications.
