If you're not sure what a wheel bearing is, it's the metal component that allows your wheels to rotate smoothly. Over time, these bearings can become worn down, making your ride less smooth and potentially damaging your suspension. That's why it's important to check their condition regularly and replace them if necessary.
There are a few ways to tell if your wheel bearings need to be replaced. First, take a close listen while you're driving. If you hear any grinding or squealing noises coming from your wheels, that's a good sign that the bearings are starting to wear out. Additionally, if you feel any vibration or wobbling in the steering wheel or pedals, that could also indicate an issue with the bearings.
To get a more accurate idea of their condition, you can also remove the wheels and inspect the bearings directly. Look for any signs of damage or excessive wear and tear. If they look bad, it's time for new ones!
