Hi All. I recently took delivery of a 2017 GLC300 4Matic last Friday. I wanted to get some mud flaps for the car so I went ahead and purchased the OEM ones on ebay. Since there are no how-to videos or instructions included with the product or posted online, I decided to put together one today for those of you that are interested in this simple DIY. Please note that this is only for the front set as I realized, after purchasing both front and rear sets, that the rear mud flaps are not compatible with cars that have the AMG/Sport package (Opt 772).

Parts / Tools Required:
Front Mud Flaps (w/o Running Board options);includes two screws and a metal bracket; Part no. A253 890 0700
Small Flat Head Screw Driver
Drill with Torx Screw Bit
Clorox Wipes
Paper Towels

Step 1: Gather your parts.



Step 2: Turn your wheel towards the side you'd like to work on. This will make it easier to remove the rivets. For this example, I'll be working on the left side (Driver Side).

Step 3: Locate the 3 plastic rivets on the wheel well where the mud flap will be mounted to.



Step 4: Remove these rivets by gently pulling the middle piece (pin) first, followed by the rivet head and body.

Step 5: Clean the area with clorox wipes then air dry or wipe down with paper towel. Ensure that the area is free if debris as the mud flap includes a 3M double sided tape to secure it to the body of the car.



Step 6: Before removing the paper backing to expose the tape, perform a test fit to the car so you'll know exactly where to attach it.

Step 7: Remove the sticker backing and attach to the car. Hold for at least 30 seconds to a minute.

Step 8: Reattach the rivets and install the metal bracket.



Step 9: You'll notice that on the opposite side, towards the bottom of the mud flap, has a little flap to secure it further to the body of the car. Note that there is no pre-existing hole here. I just simply marked it on the picture.



Step 10: Find the self tapping torx screw (includes two, one for each side) that came with the packaging.





Step 11: Using a drill, drive the screw through the hole to attach the mud flap securely.



Step 12: Work on the next side, and you're done!

After installation:






As I mentioned earlier, I bought the rear set mud flaps without knowing that they were incompatible with my car because of the Sport/Night Package. Here are the photos of the mud flap and the test fitment I did when I realized that it didn't fit well.

Part no.: A253 890 0800

Thanks for the Info. I will be doing this to my ML in the next month or so.

 

When I took delivery on my GLC in Feb. I ordered front and rear mudflaps from my M-B dealer parts department. The next day they called and said the M-B flaps were not compatible with my vehicle because it had AMG style lower body cladding.

Week before last I revisited the parts department to ask if compatible flaps were yet available. The answer was no.

The above said, the front flaps on aaron's GLC appear to fit perfectly.

 

Looks great--thanks for taking the time to document this. Hopefully, there will be back flaps soon. If so, I'll be putting them on.

 

Arron,

How closely does the color/texture of the mud flaps match the plastic trim on the vehicle. It's difficult to tell from the photos.

 

@mb4mb, here's a slightly higher res photo. The texture is slightly different and the color is just a touch lighter, but it could be caused by the trim cleaner/solution that was applied to the car when the dealership detailed it during delivery. It's not noticeable unless you're within a foot away from it.

 

Aaron (spelled correctly this time, sorry), Thanks that is very helpful.

 

if/when you have time, can you post a couple photos of the truck from a couple different angles? I'm curious to see what it looks like with only front mud flaps.

This will be my wife's vehicle, so I'm not able to clean it as often as I clean my vehicles (I generally clean them at work in my spare time.) Also Diamond White is incredibly hard to color match so the less chips the better.

 

@ec_nova Here are the pics as requested:

 

Thanks! Looks just fine with only the fronts IMO

 

Just put them on our new 2017.

Have several pics below for the rear install.

You have to pull the wheel to add the 2 screws.

They are held on by one existing rivet, 2 new screws and a new clip inside the wheel well. It also has a new screw below like the front flaps.

Very simple install. Just clean and prep (isopropyl alcohol in my case) the area so the VHB (very high bond) tape adheres properly.

I did the fronts the other day and then it rained. It is obvious that this plastic is going to be hard to keep clean. The dirt really gets down in the fine texture in the plastic.

Anyhow, I like them and it will help keep the wife's car cleaner. : ) I can't say anything however as my car in the background is dirty.

I also just purchased a jacking puck and bolt extenders from ReverseLogic. They work great.

 

I bought he OEM rear only flaps for my 2019 GLC 300. I set them aside and a few months down the line I saw the bag only had the mud flaps, now screws or plastic parts. Since I didn't know if you could could use the existing pegs to lock it in place, I wentr looking and saw this. You said you had the wrong rear flaps, did you try to screw them in or use the existings pegs. I didn't get the front flaps since I also bought running boards..

Thanks,
