I just had this happen to me and I just had it replace. I can speak from the experience of replacing the front wheel hub assembly.
The first indicator is NOISE. What type of noise? On acceleration - looking at the RPMs, the car gets louder in a humming manner - significant to the ear - not as loud as if you needed a new muffler---but loud enough (and usually under the driver side or what appears to feel like it is underneath the gas foot pedal). Additionally, if the noise tends to dissipate on turning left - (taking pressure off the hub assembly), there is a good chance.
Additionally, on the DECELERATION - loud and can feel the sound moaning very loudly as you put on your brakes.
Other things that you might notice - looser steering wheel, pulling toward one side or another (like alignment issues) - because the wheel hub assembly/bearings affect alignment.
Get this fixed. It is imperative. It can really mess up alignment or worse yet--the tire could detach from the mount/assembly. It needs to be "replaced". There are no repairs or rebuilds-the wheel hub or bearing needs replacement. Parts alone - approx $260 NOT INCLUDING labor. Most likely over a $500 job.
It gets very hard to steer
No oil pressure
Yes, a GFCI breaker can go bad. You can tell if it needs to be replaced if it is not tripping when it should, if it is tripping frequently without any apparent reason, or if it is not providing proper protection against electrical shocks.
Yes, a GFCI outlet can go bad over time due to wear and tear. You can tell if it needs to be replaced if it no longer trips when tested, if it fails to reset, or if it shows signs of physical damage or discoloration.
You can tell that your vacuum cleaner needs to be replaced when it quits working properly. Signs of that include the belt quits turning or the vacuum quits picking up dirt.
Look for a mileage schedule in the maintenance section of the owners manual.
You can't and that is why they are replaced at a set mileage as outlined in your owners manual.
