Just did my O2 sensor on the drivers side front. I was lucky the thing just came right out. I guess there's not much room for rust to get in there. Kind of a pain. Can;t get it from the top. I had to remove the drivers side axle and the axle shield to get at it. you can only use a O2 wrench. The socket doesn't fit because of how the cat is around it. I thought I could see it from the top but you can't. once you get underneith you can see it just off the manifold. the two sensors are only about 10 inches apart. small cats. I'm doing a write up for it.
