How to replace front wheel bearings on a 2001 Buick century custom?

SOURCE: what sensor lights will come on when a wheel

Hello mobrien.
Depending on what your car is equipped with. Antilock brake systems work in conjunction with traction control.So if the antilock system has a fault, traction control will also default system off. It may also turn on low pressure in a tire if your car has that feature.
In the bearing/hub assembly on your Buick there is a sensor ring that rotates with the axle. A sensor is positioned close to that ring to read wheel speed.
A failed bearing doesn't necessarily damage the sensor, nor will a bad sensor mean the bearing is bad. But on your vehicle if one fails the assembly must be replaced as a unit.
I hope this answers your question.If you have another leave it in a comment and I will answer you.

i would not try this at home, the bearing has to be pressed out and back in, and it is nessasary to remove the knucle assy.it most likely cannot be don at home with conventional tools.
