I need to replace the upstream sensors on My 02 liberty, how do I get to it? Should I remove the cat and then remove it or is there a way to drive it out? Looks very hard.

Thank You.

Well to all 22 viewers who don't care to post a comment, I got it out, quite tricky too.

Anyone know which side is bank 1 and which side is bank 2? Parts store said bank 2 = pass side and here I read bank 2 = driver side.

1 is left side ( drivers)
2 is right side

Actually they are not that hard to get to if you have a flex head O2 sensor socket/wrench.You will want to kill a engineer trying to disconnect those upstream O2 connectors though.

I find it much easier to take my hand off at the wrist and shove it up in there to disconnect that connection, otherwise its a PITA. :ROTFL:

I have that crows foot looking wrench and I put an extension on it then the ratchet... not something I want to do any time soon.
