Anyone know of the best way to remove the front o2 sensor on drivers side 2010 4x4 4.6l? Front driveshaft and cat are too close together to get a wrench in there and debating if I should remove the front driveshaft to get some room.

 

Try using a o2 sensor socket.

 

I removed mine with an open ended wrench on a 5.4L very close fit and only moving the wrench an eighth/qtr of a turn, flip the wrench and repeat ,,, maybe cut a wrench in half if need be

 

thanks for the reply. Finally got it last night with an offset socket with a closed end wrench over the ratchet for some extra leverage.
