FAQs—GMC Wheel Hub
How often should I check and maintain the condition of my car's wheel hub?
You don't need to check on your GMC wheel hub on a daily basis, but that doesn't mean you can just ignore it altogether. You should inspect your car's wheel hub every 25,000 to 30,000 miles. You can prolong the life of your wheel hub for more than 100,000 miles through proper grease application on the hub assembly.
I installed a wheel hub on my GMC a month ago. After a few drives, the seals on the wheel hub gave out. What could have caused this?
A GMC wheel hub is a low-maintenance component that can last a lifetime without any replacement. If your wheel hub fails after only a month, either you have installed the hub incorrectly or the wheel hub has a factory defect. Unless you were involved in a car accident in the past, you should check the wheel hub to see if it is properly installed or if it has defects.
My wheel hub bearing is making alarming noises. What could be the problem?
There are a number of reasons why the area around your wheel hub bearing may be making unusual noises. Usually, none of these reasons can be anything but negative. When you hear a popping or clicking noise when making a sharp turn, it can signify that your bearings are already worn due to insufficient clamping. Alternatively, when the strange noise is accompanied by excessive play and rough riding, it may be an indicator that the seal on the wheel hub bearing is broken. Moreover, a noise that has more vibrations can point you to a corroding hub lining that naturally creates vibrations that are transferred to the tires. Again, none of these instances could do you any good, so as soon as you hear unusual noises, take your car immediately to a professional to have the wheel hub checked and replaced.
My wheel wobbles a lot when I drive. Does this mean my wheel hub is faulty?
Not necessarily. When you feel like the wheels are wobbling or vibrating while you are driving your vehicle, this could usually mean either a damaged suspension component or a worn-out tire. However, if the suspension parts are fine and the wheels are in top-notch condition, then your wheel hub may be the culprit. Check your wheel hub to see if it has lost a clamp or has taken a mechanical damage.
The ABS sensor on my wheel hub is damaged. Should I replace the entire wheel hub assembly?
Yes. The ABS sensor of your car is built into the entire hub assembly. Replacing the wheel hub because of a faulty ABS sensor may prove beneficial in the long run, since it will prevent the sensor from sending false alarms to your car's dashboard.
How much will it cost me to repair and replace my wheel hub assembly?
GMC wheel hub replacements usually cost between $150 and $400 per wheel. If only one wheel hub is faulty, there is no need to replace the other three unless you want to do it as a preventive measure. However, if you're up to doing the replacement yourself, there are a lot of DIY guides out there to help you out. Of course, you will still need to buy your own materials. The only advantage is that you don't have to shell out extra money for service fees.
