What does the hub assembly consist of

Answers from the Automotive Experts

Thank you for writing in. The hub assembly is going to include the actual wheel hub (the lug bolts the wheels are attached to), and the wheel bearing (which allows the entire unit to rotate freely). Many wheel hub assemblies also include the ABS sensors and the wheel speed sensors, as it is the best spot to mount sensors that need to be stabilized and still be close enough to calculate wheel speed  After researching you particular car's wheel hub assembly, it looks like you can buy the hub assembly with or without the sensors and electrical connectors. Good luck!
