2007 volvo vnl frame rail repair help?

No way around it, it will not be a cheap, easy or quick fix.

To do it right you need to replace the frame rails. I've personally never done it but they don't need to tear the truck down to do it. They support all the main components, unbolt the old rail and slide it out.

 

Well, not so fast, AModel, sounds like this person is describing those rust "tumors" on the side of the rail. I believe the strong point is the top and bottom of the rail, not the side so much. Living and trucking in the north, practically every older truck I drove had those rust tumors, and none ever broke in half. Under the 5th wheel is a particularly bad spot. My Western Star conv. cracked a frame rail, a place put a smaller channel piece inside the original frame rail, bolted and welded, didn't last long. So I had the WS frame and spring ride cut off behind the sleeper, and had a Pete air ride stub grafted in place. They also used smaller channels, but much longer, bolted, welded, never had a problem. Replacing entire frame rails is a major job, and on an older truck, might not be worth the hassle.

 

Glove it. Not really a big deal. Just time consuming

 

I think i'd do a cutoff on that
