Friend of mine traded in his truck and he has brand new motoorcraft upstream O2's that I got for $10 a piece. Now do I need to get a straight O2 socket or a offset one?
My truck has 105K on it and I figured it wouldn't hurt.

 

Hi.

Screamin' deal on those sensors!

You need an offset socket for the passenger side, if you value yer sanity.

good luck

Why do you even need a socket to do them? Still haven't been able to find an actual concrete reason unless they're rusted all to hell. I've taken mine off 4 or 5 times now without the socket. I bought one when I did my headers, but didn't see the purpose in using it, so I didn't.

 

I can't reach the passenger-side front O2 (non-lifted 4x4) reliably with anything but. Just no room for my meathooks.

Sure - I can get a real long open-end wrench on it - but there is no room to turn it.

Once you round it off, yer SOL. Likewise, if you strip the bung, you are SOL.

Saltbelt trucks also have the pleasure of corrosion to deal with.

The specific tool for this job is that offset O2 socket. Apply plenty of PB Blaster, or other suitable spooge and let them soak well beforehand.



Driver-side is cake.

Huh, that's weird. I was able to reach mine without too much fuss, but maybe the T-case, etc. gets in the way on 4x4s? I always thought there was some weird potential to snap the ends off or something if the force to remove them wasn't applied in a certain way, but that didn't make sense.
