Front and rear what? It'd help if we had some clue what you are talking about. Include model, engine
Judging by the title of the post, he's referring to "O2" which I take to mean O2 (as in oxygen) sensor, of which there is likely one behind and one in front of the catalytic converter.
Gotta be O2 sensors - but who knows for sure! Must be how IEEE engineers talk/spell.
Kinda reminds me of a letter to Tom McCahill in (I think) Popular Science, in the late 1950's. The writer asked, "Generally speaking, is it more expensive to get hit in the front or the back?"
To which Tom answered, "Boy or girl?"
I was in my early teens and thought that was pretty racy... :>))
