Put yourself in the driver seat when your car was 20K miles younger. How about 40k? Dare to wander past 60k? Compare how your car feels now versus back then. There is, most definitely, a change in ride quality.

One component which often gets overlooked is the wheel hub assembly. It is the lone part which connects the tire to the vehicle. The wear and tear of the wheel hub can translate into the steering drifting lose, ghost road noises and insistent vibrations.

The idea is to keep the ride quality consistent. when the odometer approaches 90k, and you are seeing the aforementioned symptoms, it might be time to hone in on wheel hubs. You always want a complete wheel hub assembly with brand new bearings, sensor, and all. If a single bearing on the current hub(s) is out, it is best to replace the entire wheel hub assembly. Your car might never ride like it did 60K miles ago but this is one, often overlooked, way to maintain a consistent ride quality over the lifetime of the car.
