...Behind your front wheel well liners.

A few years ago, before I bought Thunderhorse, I was helping my dad wash his 2009 Ram 1500 when he pointed out to me that he had noticed a buildup of leaves in the front bottom corner of the front door area. It was only on the driver's side, and he noticed that it looked like there was a piece of foam there that should have been keeping out the leaves, but it looked like it had been pushed out of place somehow. Pic #1 is of the area, and also allows you to see the black foam piece.

Fast forward to a couple of days ago when I noticed a couple of leaves in the same area of my truck on the passenger's side. As I pulled them out, I noticed that it seemed like there were a lot of leaves in there. Curious, I began looking for the source and ended up bending back the rear section of the front wheel well liner. Jackpot. In order to get better access, I removed the plastic rock chip protector which shares 2 fasteners with the wheel well liner, removed the plastic piece, and bent the liner out of the way. FYI, the "screw" on the bottom of the plastic piece is really a push type fastener like a lot of plastic trim pieces are attached with. If you screw it counterclockwise, it will come out and then you have to pull it out because the screw just serves to push out two barbs that hold it in place.

I have attached a pic of what I removed from there: a large clump of leaves and some dirt. I also took the opportunity to clean the paint around the plastic piece.

I told my dad about my findings, and he figured out that that was indeed his problem; he got a good amount of junk out of there too. One of my friends who drives a 2010 Ram was over last night for Christmas dinner, and I looked at his truck and he also had a buildup in that area. Since 3/3 4th gen Rams that I checked had crap behind the wheel well liners, I figured y'all probably do too and probably don't know about it since I've never seen anything about it here on the Z. We all known leaves attract moisture, and moisture=rust=bad, especially those of you living in the salt belt who may have a dirty, leafy, and salty buildup:SHOCKED:.

Mine had no rust or anything, and I hope none of y'alls do either. I'm still not quite sure how all that junk got back there though.

Interesting. Thanks for the heads up! About 8" of snow fell last night with more on the way so as soon as it clears up I will check into this.
Thanks!:smileup: Be ever vigilant, rust never sleeps!

Went outside to take a peek in my Ram.

I didn't see any build up in mine as of yet. That being said the foam piece there was very loose. Were any of the other Ram's foam pieces lose? I mean I can move mine up and down pretty easily. It doesn't seem to lock into place anywhere.

Will be pulling the truck out of the garage tomorrow to unbolt my mud flap to see if any got into the liner.
I will have to check tomorrow if I have time before I hit the road for the rest of the weekend.
The foam pieces seem to just wedge in there; my dad removed his completely when he cleaned his out. He said it goes pretty far up into the fender.

YaHoo! Another Neil Young fan! :smiley_thumbs_up:

Ah yes, good ole rock n roll. :jammin:
Same thing with my 2013 I recently purchased. Was installing my mudflaps and pulled out a bunch of stuff from both driver and passenger wheel areas.
That is common on most trucks/SUV's. When you raise the hood, look where the the corner of the windshield meets the cowl. There is an opening where this type of debris is washed down into the inter fender and accumulates. Some times you will see the leaf material coming from behind the foam in the door jam. If you park around trees, this will be a given maintenance chore.
I'll be doing an inspection after work, thanks for the info.
Was wondering if the passenger side was affected, thanks way2low01. Looks like we will need to keep an eye out in both areas!

Im glad you linked this post of yours up recently. As I pulled out shit loads of oak leaves ( least as much as your pics) that must have entered there when it was on the dealers forecourt. I noticed it when installing my mudlfaps at approx 400 miles on the ODO and 6 days of ownership garaged. How the hell did they even enter there? From the top cowel where the wipers are somehow I think. Same specie of leaves also .
Yeah im pretty sure thats where they got in. That is around the same area that water comes out when it ejters through the drain holes in the cowl IIRC
You guys are lucky you can fix it.....on the 3rd gens the inner bed fender has a stupid foam piece where it meets the outer bedside that just so happens to absorb moisture, this leads to rust that can't be prevented.

So THAT explains why I have seen so many Rams with rotted out bedsides.....

Hopefully they addressed this in the 4th gens?

Yes they changed it lol! 1st thing I did when my dad bought his 4th gen was to ensure that there was nothing there, If there was I was going to use a long pick to remove it then spray bed liner there.

I wouldn't count on bedsides not rusting. My passenger bedside was replaced after being rear ended when the truck was 10 months old. There was considerable rust above the wheel on the innermost panels. I've since removed the liners every year and sprayed krown into the 4 holes that are in the supporting bracket where moisture gets trapped. I've also seen a few trucks that look like 2009-2011 trucks in Ontario with rust bubbles or rust through above the rear wheel well.
I'm counting on my body panels not rusting out. I can only think of one time I have ever been through road salt in my truck
