Today on this 2012 GMC Sierra, were going to install part number HL57801. This is a rear mud guard set. Our first step involves cleaning the body work of the truck and inaudible to install the protective film on the back edge of the inaudible. However, in this case the truck has already a protective film installed on it so were going to skip that step. This is where the protective film prom the factory is and our mud flap will be stopping just right here. So well go ahead and hold our mud flap up.
There are no pre-existing holes in here so well mark and drill everything up. The first hole that we are going to mark and drill will be this one right here. Then place the mud flap in the proper spot and then were just going to use the mud flap as template for the rest of the holes. Alright, we can go ahead and drill the hole. Well use a right angle drill inaudible shorten it up so it barely fits in here.
Now inaudible better off for moving the rear wheel inaudibleinstall the mud flap. inaudible right into the hole. inaudible in position and inaudible the rest of the hole and install the hardware along the way. With the passenger side of our mud flap set and installed, well repeat the same process on the drivers side. And that will finish it with part number HL57801 rear mud guard set..
