Bearing whine will be obvious on start, so is a burned armature. There's nothing that can really go wrong with the table itself.

The motor is the most important thing on these things and the one most likely to give up on you, as alot of people just overwork them by cheaping out on disks and pushing on the saw instead of letting it cut at it's own pase.As i said before you will hear it if there is a bearing problem. A burned armature or spent brushes would give out lot's of sparks, unstable RPM, it would cut out randomly under stress, it's would smell burned.

The table is basicaly two slabs of aluminium and a couple of roller bearings, so the only thing to go wrong is if you loose the travel lock or one of those little legs for leveling.
The arm that the saw is riding on has two plastic bushings, that can get worn out, but it's something that can easily be felt the moment you pull the saw towards your - you will feel the entire thing being unstable and wobbly.
Last is the tilt mechanism that requires a spring to move back up, but again, it is something that if broken you could pick up the moment you put your hand on the handle.
