Your vehicle has four wheel hubs. Each wheel mounts to a hub. The hub is also responsible for connecting with the axle, as well as for supporting the
. As such, it’s an integral component. To find your wheel hub, you’ll have to take off your tire, the caliper and the rotor. The hub will be a piece of round metal with the lug bolts mounted in it (the wheel bearing is mounted inside the hub).
When should I replace my Wheel Hub?
Generally, wheel hubs only need to be replaced if they are damaged. It’s very difficult to damage a hub – usually a serious auto accident has to occur to do this. However, hubs may need to be replaced if the vehicle has been sitting outdoors for a long period of time and the hubs have rusted. Most drivers will never need to replace a front wheel hub or a rear wheel hub, but if you’re restoring a car, or repairing one damaged in an accident, you’ll need to know how to go about it.
What happens if I don’t?
If you don’t purchase a wheel hub replacement, there are several things that can happen, although these will depend on what’s actually wrong with the hub. If the hub itself is compromised, it’s possible to suffer catastrophic failure, which would cripple your braking ability, as well as your ability to drive. It’s possible that a damaged hub could impact the wheel bearing or wheel race as well.
How to do it: Replacing your Wheel Hub
- Verify that you have the correct discount wheel hub replacement for your specific vehicle.
- Jack up the side on which you’ll be replacing the wheel hub.
- Remove the wheel and tire.
- Remove the caliper and secure it under the vehicle with a bungee cord (don’t let the caliper hang from the brake line).
- Remove the brake rotor (these are usually secured with screws that go through the rotor into the hub, and you may need to use a hammer driver to loosen them).
- Remove the dust shroud from the wheel hub.
- Remove the cotter pin from in front of the axle nut (if your hub is secured in this way – some are bolted to a backing plate on the axle itself).
- Remove the axle nut (again, if this applies to your vehicle).
- Remove any bolts securing the hub (these are often Torx bolts).
- Tap the hub from behind to remove it from the steering knuckle.
- Clean the steering knuckle-hub mount area.
- Install the new wheel hub replacement.
- Reassemble everything in reverse order.
