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.
