front bumper removal:
From club lexus-
"""""Just go slow your first time, and take special note to remove all the clips and screws. You'll need to remove that plastic
radiator cover first, then the three plastic clips in the bumper under that radiator cover. Now, you've got about 15 different screws/bolts, youll have to remove from underneath in order to free the bumper from the skid
plates and what not. Remove the ones that attach the fender lines to the bumper too.
I usually try to completely disengage the fender liners from the bumper
before attempting to remove it or loosen it at all. They are highly restricitve if they are still attached. You'll also want to reinstall these first when you put the new bumper on. They tuck back into the proper places really only one way. You'll get it.
Also at the corners of the bumper when you're ready to try and remove it, first you need to remove the plastic clip and
screw you find tucked up in that fender well area. Then, you'll need to pull down slightly and out. THis will remove that notch holding the edge of the bumper. Now, you need to gently pull and wiggle the bumper away from the front of the truck focusing on that area where the bumper and
fender square to each other. Theres a rather large lobe that interlocks those two and it can seem stubborn.This should dislodge the lobes much easier than just yanking on it furiously. Those lobes actually start where the bumper sort of squares itself right at the
metal fender. You'll see what I mean.
Repeat on the other side
Good luck, once you get it off the first time, it'll be a piece of cake putting the other one on! """"""
