Out of curiosity what did the dealer charge you?
Did all mine this past Sunday. Did them all from the top and had to use a step stool. Passenger side I was basically laying on the airbox and reaching down. Thought about going through the wheel well, but the time it would've taken to jack up and remove the wheel and liner I would've been done.
The back plug pretty much had to do by feel.
I loosen the plug with socket/extension then I have a 4-5" length of 3/8 hose (I think) that I stick over the insulator and use to unscrew it the rest of the way. After applying anti-sieze I put the new plug into the rubber hose and use it to get it threaded finger tight then use torque wrench for final tightening.
