The rave just says to put the truck on Jack Stands and remove it with a crows foot.

Did you go at it from above or from below? Crows foot wrench? Oxygen sensor socket? Open end wrench?

Just had a thought that it might be easier to just drop the exhaust Y pipe, but haven't had a look at that yet.

Was hoping to get this done yesterday,....now hoping for today.

Your help appreciated!!

I used a oxygen sensor socket and got it from the bottom. The oxygen sensor socket i used had the square drive off set like this one. Performance Tool W84008 - O2 Socket | O'Reilly Auto Parts

 

I cleaned the socket with a wire brush (it was covered in mud) soaked it with PB blaster (I was swapping them out) and used an adjustable wrench

 

I pulled the cross member, dropped the Y-Pipe, and pulled the o2's on the shop floor.

Before warned the manifold bolts may give you a hard time and may strip during removal. Just something to consider before choosing which way to go.

 

I would suggest a oxygen senor socket or a box wrench; a crows foot or open end will most likely slip and round the sensor.

 

I bought an offest O2 sensor "socket" (actually more like a crows-foot than a socket), and did the drivers side from underneath with a 6" extension, and the passenger side from up top. It's easy to get to. No need to put the truck on jack stands,....just some cardboard underneath so you can easily slide around as needed.

Update to my update: As others have mentioned, spray the O2 sensors with penatrating oil of choice, then run the engine for 10 minutes and let it cool for a few to let some of the heat out of the pipes you might be working around. My O2 sensors came out with no resistance at all.

This ^^^^^^^^^, and a 1"x9" Galvanized nipple (cheater bar) to go over
your ratchet handle.

 

I followed the suggestion of others here and sprayed the O2 sensors with PB Blaster (or similar) and then warmed the engine for 10 minutes. Then, after a brief cool down,....found they came right out,.....no effort at all...................really.
