Geo Tracker Locking Hub

Common Geo Tracker Locking Hub Problems: Reasons and Solutions

You would think that a small part like a Geo Tracker locking hub will not give you headaches; how wrong you are, buddy. As an important part that could risk the performance of your vehicle, the locking hub presents problems of its own. We listed the common issues with these hubs as well as solutions that can help you solve them.

Noisy locking hubs

There are times when noise can be heard when the locking hub is turned, regardless the degree of the turn. The noise is heard as a somewhat cracking or snapping sound and is sometimes heard when the car is driven straight. If this is the case, the u-joint could be the part to blame. A quick check of the bolts would be helpful at this point. Check the condition of the u-joints and replace or retighten them, if needed. It wouldn't hurt to do check the wheel bearings while you're at it.

Hubs won't engage

Yup, pesky locking hubs that won't lock are not just ironic but are also common problems for drivers. This problem would not only give you a headache, but it may also lead to an increased fuel consumption, faster tire wear, and drivetrain noise. To check if you have faulty locking hubs, you need to do a test drive or raise the front wheel to inspect if the hub is indeed engaging.

The problem is likely caused by mud or rust that was built-up in the mechanism. There are also chances of small parts inside the hub or within the assembly wearing out and are in need of replacing.

Hubs won't disengage

In the same level of being irritating as the one above, the hubs may fail to disengage. A symptom of this problem is the loud popping noise coming from the locking hub. The noise is caused by the vehicle continued performance as a four-wheel drive.

However, before concluding that what you have are indeed hubs that will not engage, it would be better to back your vehicle a bit to try to engage it. If this fails, then what you need to do is a simple check of the assembly and a clean-up, just as mentioned above.

  • Ways to Keep Your Geo Tracker Locking Hub in Shape

    You may think that a part located at the wheel is bound to get damaged and be in need of replacement quickly; well, it definitely is but that is not an excuse to just wait for it to get scratched or break in half. There are a lot of simple ways you can do to at least prolong the service life of your Geo Tracker locking hub.

    Do a regular check-up

    For cars that are only driven on streets, it is advisable to inspect the locking hubs after 24,000-30,000 miles of driving, which is roughly equivalent to two years. Check if the hubs are damaged or have become loose. It would also be great to have them lubricated after the inspection.

    For cars that are driven off-road, a more frequent inspection is needed. A quick check every year (or less depending on how extreme the terrain that you drive on is) would be great.

    Clean properly

    In case you're wondering, no, splashing water on the locking hub while it is bolted on is not proper cleaning-even if you do it regularly. You would need to take the assembly apart and clean the parts separately.

    Pick and use a cleaner solvent that is not harmful to nylon or neoprene rubber (you can check this with the label of the solvent). For the hub's o-ring, it is best to avoid petroleum-based cleaners because they can cause swelling which will eventually lead to a dial that binds and sticks. Soaking the o-ring in silicone spray or transmission oil is also best avoided.

    Be sure not to leave any grease in the assembly as it may cause early buildup and eventually damage the locking hub.

    Gently remove the locking hubs

    If you need to disassemble the locking hub (for cleaning or for a DIY task), avoid using pliers or channel locks; using these tools on the locking hub risks damaging the hub lock. It is best to stick to your hands or grip gloves to protect the surface and, possibly, the paint and finish of the hub.
