05 murano upstream o2 sensor replacement help

[Gweedo43]

My 05 Mo needs both upstream O2 sensors replaced. I have read the service manual and to access the rear one, it says the plenum has to be removed and yada, yada. Does anyone know if there is an easier way? Any advice would be amazing and appreciated!

When my alternator went out, i read the service manual and started removing things when i realized i couldn't wrench the bolts with my shoulder needing surgery, so i took it to my mechanic. He called and asked why i took parts off under the hood when it can be taken out through the wheel well. I ended up paying extra to have the parts i took off back on. I now question the engineers that wrote the book and ask the people that are smarter and actually work on them. Thanks :-)
