Got 113k on mine and seen lots of sand and water and I've never touched em, bit then again, my motto, if it ain't broke don't fix it, so they might freeze tomorrow!!

When they go bad you will normally get a vibration, along with a knock in turns/bump. Jack up a corner and give the wheel a good up/down then side to side shake and if you feel movement it's probably either the hub or ball joints. If you have someone else do it while you look on the inside of the wheel area you can see which it is easily.

As far as how long they last, too many variables to say. Tire size, wheel offset, how often and how hard you wheel it...

The bearings are actually inside a sealed unit-bearing hub. The bearings themselves aren't serviceable or greasable, you just replace the entire unit-bearing hub. It's a pretty good design actually and most last well over 100K miles.
When you have a choice, buy American.
