Mercedes GLK 350 4Matic (X204) M272 engine O2 (Oxygen) Sensor Replacement (detailed video)

This is a video showing how to replace the two O2 (Oxygen) sensors on the right catalytic converter on a 2011 Mercedes GLK 350 4Matic SUV. I also show how to swap the (much easier) single sensor on the left catalytic converter. This video was filmed with the front driveshaft removed which makes it easier to understand (the front driveshaft snapped off and bent the two right O2 sensors, which is how the car was when I bought it). If this video helps you, I&really appreciate it if you&like it and subscribe, so it&be easier to find your way to this and other related videos I&made, or will make. Thanks!
