    So I am replacing all 4 of my o2 sensors on my 2014 Trd sport 4.0L with 235k and I cannot for the life of me get enough space on B1S1 (passenger side closest to exhaust manifold) to get a ratchet and crows foot
    Adapter onto it to loosen it. I have tried about every angle I can fins and cannot get enough purchase to get it loose. Anyone replaced theirs and have a good trick of the trade?

    This is the tool I used on my front O2 sensors, I don't think any other tool would've worked the space is so tight, it was still a pain because mine threaded out tight the whole way. Also I know Amazon has the tool for cheaper but I've seen it in stores if you need it asap. I went under the truck and fished the tool between the frame and cat to get the right turn on it

    I appreciate that. I tried using my swivel on the o2 sensor crows foot tool without lock and there were just too many pieces so this will hopefully do the trick.

    If you're 100% committed, simply cut the wires and use a deep 22mm socket.

    I am 100% committed and may give that a go.
