Rear Bumper Help

Hello to All,

I am installing a trailer hitch from uhaul on my 2007 double cab. don't have to remove the bumper to install this hitch but there are two screws that have to be put down throught the bumer (on both sides of where a bumper mounted ball hitch would go). the bumper has a plastic cover on the rear bumper. how do i remove this plastic cover wothout damaging it? thanks for the help.

 

it's held on by clips on the back, look underneath the bumper to see if you can use a flathead screwdriver to help you push on the clips...
i removed them when bumper was off the car...but i think you can do it from underneath np

 

thanks. do you know of a link where i can see pictures?
