03 V6 B1S1 O2 sensor help

[nasdamus]

Hello! I need some help/tips for changing out the B1S1 O2 sensor on an 03 V6. I can't seem to get this thing! There's just no room to work it. I have tried a breaker bar (no room to move it), an O2 sensor wrench, an O2 sensor socket. I have access to a lift and tried removing the tire and attacking it from the side (will be real easy to disconnect once off that way) and even from below. I can't get enough room to move/rotate anything. Anyone have any suggestions that's done this one? I can provide pics too.

Try a youtube search on "4runner o2 sensor" bunch of videos there. Haven't looked at any but someone must have put something up that will show you. They are a PITA.

Thanks! I actually checked that one out. It's a V8 so i don't know if there's any extra room, but when i got the breaker bar on it i had maybe less than an inch wiggle room. I'll keep trying though.
