Pray-tell, why are you replacing your Post-Cat O2 sensors... I've never heard of them needing to be replaced...

Yeah I second this! If you're throwing a code for O2 sensors, you only need to replace the pre-cat sensors.

Depends on weather they are seized and then the threads strip. Can be a bit of a nightmare if all goes bad.
