I answered that question today when I took my bumper cover off and cleaned behind ac condensers. I know its been covered a bunch of times but after this little project it made me realize how much crap is in there. This is a must and not hard at all it took me about 2 hours and I will rate it a two on the difficulty meter. If I wouldnt have smashed my finger putting my wheel back on I would have given it a one. Ten being the most difficult.
This is the drivers side.
Passanger side
