My 2021 Ford Bronco needs mud flaps

The mud flaps came in two boxes with 2 mud flaps in each box. The boxes were exactly the same and didn’t say front or rear on them. Thus I decided to make the first box I touched the rear mud flaps. I started by removing the things in the first box.

The box had 2 mud flaps, 8 screws, and 8 washers.  The screws were 5/16 hex size. After that I separated the items to keep them organized.  Then I went over to the Bronco and removed the fender flares from the rear.

Followed by grabbing the mud flaps and deciding where I wanted to put them. I found quadrilateral shaped plastic pieces on both sides that were under the fender fares. They both were screwed in with 3 screws. I removed them and tried to use them for a guide for the mud flaps but that did not work. The guide was 3 screws in a vertical line but I needed to make a triangle with the screws to keep the mud flaps attached to the Bronco securely. 

What I did was use a drill bit that was smaller than the screws and pre-drilled 3 holes in the mud flaps. Then I put the washers on the screws and used my electric ratchet wrench and a 5/16 socket to get the screws in the mud flaps. But did not go all the way through until I placed them on the Bronco in the right spots. Then I went through with the Electric Ratchet Wrench and got the mud flaps connected through the plastic of the Bronco on both sides.  

After that I gave them a good tug to make sure they were on good. And put the rear fender fares back on. I measured how far they were off the ground and discovered  the rear left was 11 inches and the rear right was 10 inches off the ground. I was just eyeballing it when I was figuring out where to put the mud flaps. Being off by an inch is not really noticeable.  I didn’t install the front mud flaps until a week later. To make sure that the rear ones were not going to fall off first before continuing. 

One week later and the rear mud flaps did not fall off so I went on ahead with installing the front mud flaps. I did the same process as the rear mud flaps by removing the front fender fares first. There were no quadrilateral shaped plastic pieces this time. So I moved on to figuring out where I wanted to place the mud flaps. Next I pre drilled 3 holes followed by putting in the 3 screws with the washers in a triangle formation. For both front mud flaps and I was done. Once again I measured how far they were off the ground and both were 9 inches off the ground.
