For the 2002 to 2008 Rams rust over the wheel wells is an awful, but common sight. My question is for the people out East if this mess is showing up on the 4th Gen trucks?
Thanks.

The newer trucks have full wheel well liners, at least my big horn does. Should help prevent the massive rusting.

My Boss's son has a 2013 Ram 2500, typical rust out above the rear wheels is already reared it's ugly head, esp with the truck being white, both sides, drivers more prevalent, this winter's salt usage will clearly blow the blistering bulging mess out....

Oh awesome.  Thanks to the Ram Engineer who decided to go with general motors' sheetmetal on the 3Gen and up trucks.  My '01 is still far from rusting (West Coast) and so are most of the other 2Gens out here. Those wheel-liners make the problem worse: all the salt and spray finds its' way up into the box and the liner doesn't let you get a pressure washer blast in there. You either have to pull the liner out everytime you wash or pull out the tail-lights to access inside the box panels.

Along the upper wheel lip of the bed they used a spray-foam like material and this is where the rust is coming from after it gets wet and rusts from the inside out. Mine has started and will most likely have new bed sides installed.

My 05 has the same problem (not that bad yet though). I don't think its bad metal, I think it's a design flaw, there's a big gap where the inner box/wheel well structure meets the outside of the box. There's drain holes there but they're too high up and mud forms in a 1" crevice at the bottom of where the panels meet, exactly where the rust is in your picture. You can clean them out by pulling the tail lights out and spraying the gap between the out and inner box from there, but that's a pain. The ones I've seen around here that aren't rotted out have be wheel well liners, so they seem to help
There is also some kind of foam where the inner and outer panels meet. I've seen some trucks with so much in there that it covers the 'drain' holes (yes, they are up high) while on some trucks there isn't very much foam in there.
I'm not sure what the purpose of the foam is or how much is actually supposed to be in there. I think maybe it is supposed to keep water from getting to the area where the inner and outer panels meet but I think it eventually starts soaking up water.
It's not really a pain to pull the taillights, two screws and pop them out and wash inside the wheel wells. No one seems to take the time to do it though.
I haven't seen any of the '09-up trucks rusting around here so far.

Excellent information, Dallas, thank-you!  Have you had an '09 and up apart to see if they have the foam?

They are rusting here really fast & really bad. THE PROBLEM IS a sheetmetal bracket panel that is welded on to give rigidity to the upper part of the wheel opening - it runs very close to the outer skin of the bedside & traps mud & moisture. You can feel this if you reach up there. On trucks with the plastic wheel liners, you have to remove the liners to access this inner panel & once you reach up there & feel it, you'll understand the problem. What I did on my 2008, was thin out with mineral spirits some Texaco rustproofing I have & sprayed it all around in this area, then I put on an old cloth glove & took a handful of the goopy (full thickness) undercoat & smeared it all around in the entire wheel lip area. NO moisture will ever reach those areas on that truck anymore. I traded it in back in 2012, but I'll be whoever has the truck now has no rust there! (BTW, the Texaco rustproof formula is no longer available - it's been gone for years, but it had the consistency of thick grease. I would substitute for a grease & I think you will get the same effect. The grease will never turn hard & it will always displace moisture).

Guy I work with has a 2011 that is showing rust on the front fenders. He keeps it spotless and barely drives it, has a company truck for the daily commute.

You treed me about the foam..lol..
Yep, the best repair is new bedsides. I haven't had much luck with repair panels holding. The 'cheap' repair is fender flares...

My truck doesn't look like it has any foam, it's the mud that forms in there thats rusting mine. How come replacement panels don't hold? Are they poorly made?

I just bought a 06-07 rust free bed to go on my 05. no rust on outside look inside you can see rust in wheelwell area (bed is upside down on trailer easyto see) I drilled spotwelds took out outer fenderwell. lots of rust in there cleaned it coated it with KBS coatings (POR 15). would have rust holes in a year if I hadn't done this.
thinking abought spraying used oil everywhere I can once or twice a year

At one point you could blame operator error on the quantity of seam sealer that was applied to the area above the rear wheel wells. It was applied strictly by the operator on the joint before the inner and outer bed sides were spot welded together at the marriage operation. I did that job a few times. Once you got the hang of it, it was far from the worst job in metal shop. The fact that the seam sealer was applied prior to spot welding may be why it looks more like foam than seam sealer, the spot welding process probably boiled it from the heat of the welding process. It wasn't a foam when it was applied to the bed sides sheetmetal parts.  When they retooled for the 2002 body style they completely redid the metal shop and automated more of the process, whether that process was automated I can't say since I was in the chassis dept by them. They spent $200 million to redo the metal shop for 2002 and the closed it all and tore everything down 7 years later. Go figure.
