For any of you driving a 3rd Gen. Dodge Ram 1500, 2500, or 3500 and have had your driver's side seat foam fail you. I have the cure. If you have a Lowe's and a Hobby Lobby near you, it'll only cost you around $13.00 and a little skill rather than $152.00 for new foam from the dealer. Not to mention, that new foam is going to fail you just like the old one.
Here's what you'll find when you peal back the upholstery.
While searching the web for an after market part or easy inexpensive fix, I came across this link in a Dodge Cummins Diesel forum.
The frames of theses seats have a boxed frame that joins on the top of the frame and leaves an exposed sheet metal edge. This edge in addition to the sliding motion getting in and out of the trucks is tearing our foam.
Seat frame; notice the metal edge, but also notice the wires held by springs, more of that later.
The weld at the very back had some burrs, they may have started the tearing of the foam. I took a ball peen hammer, rolled the edge of the metal down, and then filed the burrs and any protrusion I thought might tear the foam.
Before reinstalling the foam, I glued some burlap over the frame. (Sorry no pic of that.)
(Burlap is approx. $2.99 a yard at Hobby Lobby. 1 yd will do 2 seats.)
For the wires with the springs, this is where the pad needs to go, directly on these springs. The springs are what provide the cushion when hitting bumps and stuff. The foam design intends to distribute the weight with out fatiguing your butt. (I donít think they quite got that part down yet.)
I used 2 inches of foam, 1 inch of 20 lb & 1 inch of 40 lb. I also place a piece of vinyl between the foam and the springs to prevent the springs / wire from tearing the foam. 20lb goes on top, it's softer.
(Hobby Lobby carries a 14"x14"x2" piece of foam that works perfectly. No cutting necessary.)
(Also, be sure to glue a piece of burlap to the bottom of the 2" foam. If you don't it'll start snowing under your seat from deterioration. The burlap strengthens it too.)
Pic just shows where it goes, doesnít include all the layers. Iíd get busy and forget to take pics.
All the tears Iíve seen, start along the bottom or the back corner, just like mine. I also noticed mine had a big air pocket where the mold wasnít filled correctly. Thatís exactly where the tear started.
I filled all the torn gaps with glue, (Weldwood landau top adhesive.) and pressed it back together. Then I glued several layers of thin burlap to the foam.
(Lowe's carries a spray on 3M water based adhesive...works great.)
The center of the seat will rise with the pad added between the frame and factory foam, while the sides stay the same height, this takes the pressure off the hips & or butt.
The edges at the frame are fairly thin because the factory cushion is molded to fit around the frame. To help offset these deficiencies, I added a Ĺ inch of foam to the outer and back panels.
(The 1" green foam at Hobby Lobby works just fine. You sit a little higher than you used to, but it'll settle in time.)
Pulled all back together, the seat has a slight ďpoofyĒ look, but itís a heck of a lot more comfortable, and should last much longer too.
(Mine looks like a pillow top mattress...and I love it.)
I give all the credit to "cntryby" of the Dodge Diesel Cummins Forum.
