The rear one has no effect on how the engine runs... It's only there as a comparison point to check how well the cat is working. If/when it finally fails, then the ECU will think that the cat has problems.

Find your year & engine on the list - pay attention to if you're a CA emissions truck.
DO NOT USE A GENERIC SENSOR. It won't work and/or it won't last.

i guess it makes no sense then to replace the rear. but should I replace the front after so many miles even if i'm not getting trouble codes?

What I'm getting at is that "Given that we're talking about 16 years and 215,000 miles, it can't _hurt_", but it may not change anything either.
