Video Transcript for Husky Rear Mud Flap Installation - 2012 Toyota 4Runner

Today on our 2012 Toyota 4Runner, we're going to install the Husky Liners Custom Molded Mud Flaps, part number HL57921. This Husky Liners' set of mud flaps will be installed on the rear wheel well. Now, to make the install easier, I've gone ahead and remove the wheel. Once you identify the driver and passenger's side, we're going to go ahead and take the driver's side here and match it up with the vehicle. I need to identify the area that need to be cleaned so that we can put a clear film in between the mud flap and the paint. Our clear film will run from the top of the mud flap where it meets the plastic body underneath the vehicle.

So I'll just make a small mark here and then I'm going to take a permanent marker and just make a small dot on the inside that will get covered up when we install the mud flap. Now, I can take some cleaner and we want to spray and clean this area thoroughly. This way, our clear film that we put on would adhere well. Now that we've got our area prepped, there are a few fasteners that need to be removed. Next, I'm going to show you quick tech tip because our clear under laminate film will stretch all the way to the edge of the paint.

There is a pushpin underneath that will get in the way. To make it easier to install the film, we're going to go ahead and remove this pushpin. We need to get underneath the center of the pushpin and pry it out, and then once we had the center pried out, we can go ahead and remove the whole pushpin. Now, I will recommend that you go ahead and clean the area again just to make sure no additional dirt got in the way. Now, we're ready to go ahead and install the film strip.

To do this, we're going to apply a soak and water mix then we'll take the pre-cutout strip and put it in place. I'm going to start at the bottom edge of the paint and work my way up. Now, we're taking a squeegee or a sponge, or even a household soft spatula. We're going to go ahead and squeegee the water out from underneath the film strip. We want to push all the water and air pockets out from underneath.

Next, we're going to go ahead and allow our film strip to dry and set up nicely before we can install the mud flap. Now that our film strip is set up, we're going to go ahead and go back underneath. We'll remove our pushpin tab. I'm going to take a sharp razor blade and cut a slice through the film strip so we can reinstall the pushpin. Now with our pushpin reinstalled, we'll move on to the next step which is removing the three fasteners on the inside of the wheel well. These pushpin fasteners will be removed and will not be reinstalled. Once again, we're going to pry the center of the fastener out and then remove it. Now, to install the mud flap, we'll be using three screws. In order to install the screws, we need to install three new fasteners. These are going to go behind the inner wheel well and snap into place where we just removed the pushpin fasteners. Now with our fastening hole down is in position, we'll go ahead, put our mud flap in position with the screws provided, and with our three fasteners installed, we can go ahead and reinstall the wheel. And that will complete the install of our Husky Liners, part number HL57921, on our 2012 Toyota 4Runner.

How much wider and taller are these over stock mudflaps on a 2012 4Runner Trail Edition? Thank you
-- comment by: Karl - 12/31/2013

We do not have a Trail Edition here to compare to, but I can provide some measurements on the Husky mudflaps. Overall width is 11-3/4 inches, overall length is about 17-3/4 inches. The portion that extends below the bottom of the fender measures a little over 6 inches.

I love them. They work great and look great. I did notice the other day that one of the mud flaps was missing a locking piece. Not sure if you can help with that. Thanks for reaching out.

Not a problem at all. I just got of the phone with my contact over at HuskyLiners. They'll have some hardware on the way either tonight or tomorrow. It'll arrive via USPS.

Overall I like them. I got them to keep the mud and snow off my running board. They do a decent job of that. I think if they were a few inched longer it would be perfect. I have em on both vehicles and would buy em again. 441822

Perfect fit for the S10 ZR2 with factory flares; uses one of the factory mounting screws and then you drill two new holes. Took about an hour to install as I removed the tires. Will have to see how they hold up to the wind - may come back and add a little silicone adhesive for extra security. 80521

I installed these Mud guards on a 1996 GMC Dually with factory dually flares. They fit and look like they belong with the factory dually flares - exceeded my expectations. All I did was slot two holes to allow for factory variances in panel fit (occurs on all vehicles) and I replaced the supplied sheetmetal screws with stainless quarter inch bolts/nuts for stronger attachment points. Very easy installation. This fit and custom look is far better than flaps blowing in the wind. Highly recommended! 129195

Review from a similar Custom Molded in Mud Flaps


Good product so far - just installed them yesterday. The wear protection film wasn't pre-cut, but was easy enough to trim to fit using scissors, and I just stuck the film directly to the truck without using the soapy water solution called for in the instructions. The film stuck to the truck just fine, and the flaps fit perfectly and look great. 456764

Great fit! Easy to install on my 2007 SD 250 w/Factory Fender Flairs. I received a call from one the trailer reps to let me know my order would be delayed. The unit was out of stock. I was offered to have my shipment delivered direct from the manufacturer at no cost to me. What a great company to deal with...I will be ordering other items in the future. 219530

Website was good about choosing which mud flaps were right for the vehicle. I ordered, and within minutes received a phone call from etrailer saying they were on back order and would be shipped on a certain day. Sure enough, they were. The flaps are far better quality than came from the dealer (the back ones). Instructions are easy, and the flaps fit exactly on my truck, and very easy to put on. Holes matched perfectly, and they're on in just a few minutes. 114723

Thank you for the note and followup. Its a first for me from any company, frankly! The product is still as I stated, holding up like new, and just no problem whatsoever.

Review from a similar Custom Molded in Mud Flaps


The mudflaps installed easily for the most part. I still have to drill some holes for the rear mudflaps. I need a right angle drill, so I don't have to remove the dually wheels in order to drill the holes. These seem nice and sturdy and well made. I am not sure of the length of the rear flaps yet, seems they should be longer than they are. Good product, haven't tried them out yet to see if they deflect debris well. I am hopeful. 584363

Super easy and fast install. Look great. Covers tire tread. Mounted without even having to turn or remove wheels. Removed factory screws, placed guards into position with holes which lined up exactly and re-installed screws. Very pleased with Husky product and etrailer service. Will be ordering fronts now. 111111

Review from a similar Custom Molded in Mud Flaps


I haven't gotten then put on yet, but I did fit them in place. They fit perfectly on mauck up. I do wish they were a bit longer in the rear, I'll see how well they work on my muddy roads. Not really clear on the instructions of the paint protectors. 562030


Comments
Basically you want to place the film on the fender where the mud guard will touch. Clean that area of the fender with a adhesive solvent. A solvent will insure there is not any residual wax, grease or dirt left on the area of the fender you will be placing the film on. After cleaning the fender, create a wetting solution with 4 ounces of liquid dishwashing detergent and 1 pint of water. Take the backing off the film and spray the sticky side of the film with the solution. Spray the fender with the solution. Place the sticky side down on the fender and flood it with the solution. Then press the bubbles out of the film with a sponge. Allow to dry before putting on the mud flaps.

Review from a similar Custom Molded in Mud Flaps


Overall these are great mud flaps. I had no problem mounting the back ones but, on the front when you are required to use the factory hardware, the screws are too short. Luckily I had 4 similar longer screws on hand to use. I opted to use all the mounting screws instead of relying on the 3m tape alone. I put these on a 2019 Ford F250. If I didn't have to mess with having the wrong length screws I'd give them 5 stars. 595042

These are what was promised. Easy mounting, all the screw holes matched up and the fit was exact. The flaps are full width (of the stock tires). There were no burrs or plastic shavings to be dealt with. They very road use durable (haven't tested them off road) and do what a mud flap is meant to do. 518023

A year into use the mud flaps have held up well and still look good. These still get 5 stars from me a year later.

    Add-on fender flares are hard plastic flares added to the metal around the wheel wells, typically found on the Trail models. The add-on flares are what will prevent the mud flaps from being used. If you have the metal flares that are formed into the steel around the wheel openings, and do NOT have the factory running boards, the front mud flaps you referenced, part # HL56921 will work just fine for you.
