I was up in Colorado this weekend going over a couple passes I'd never been over, Black Bear and Imogene, and I ran into a small problem.
The spring pearch for my right rear leaf spring came off the frame, along with the piece of the frame it was rivited to. This happened a little more than half way up Imogene. It had probably been broken for a while and I think I unloaded that side of the axle anough to allow the axle to move back and rub the back of the wheel well/fender flare.
We managed to get the 40 to a somewhat flt spot and jack it up to fit the piece of frame where it had come from. When we let it down the weight of the vehicle seemed to be keeping it in place. We figured it would last for while but probably not the rest of the trip. We tried a few different things to keep the pearch from moving front to back but none seemed strong enough. Someone had the bright idea to use the winch to hold the pearch. The hook wouldn't fit between the spring eye and the pearch itself so we took the hook off and slipped the cable through and reattached the hook. A little tension on the cable and it wasn't going to move at all. We also wrapped a strap around the frame and pearch to help prevent any side to side movement. The whole thing worked really well.
I found a fix for this problem after searching for a while after I got back. I'll be modifying both sides with a large gussets very soon.

Yep.. Common problem. Keep an eye on your front frame horns as well.
 
WOW!!! Good thing that happened on Imogene instead of Black Bear.

It may have been broke on Black Bear, although I'm really glad I didn't have to find out untill later. I had been hearing a noise that I couldn't find for most of the day. I must not have flexed enough coming down to make it pop out of place. When I look at it now it doesn't look like its cracked.
I found a post from someone who came up with a fix using a 3"x3"x3/16" square tube cut like a triangle with the long side 5". I apologize that I don't have there name handy but I have pics of the fix. This is what I'm planning on doing with mine. It looks like it should last for quite a while.

I think that is Claudia's truck. Poser did mine and made the gussets out of three pieces of 1/4", IIRC.

Sorry, those pics were not of my truck, but they are of Poser's work. He did use 3/16"......here is my truck:doh:

This is the right front, I'm glad I looked. This is getting depressing.
Anyone have any words of wisdom?

had the same break on the front, boxed the frame and no more issues

exact same break as yours
 
Weld'em up and keep wheeling. Had the same break in the rear as you on the first day of a 3 day event. Got it welded at a local shop and wheeled the rest of the weekend. Hasn't failed in the years since....

Man. That welding is top notch stuff!!!
 
it seems like that at the very least, you could weld the seam where the main c channel of the frame meets the box channel insert to keep that lower section from flexing. sure the frame as a whole is boxed, but with rivets. the attachment of the hanger is very localized. a simple weld bead at that seam alone could maybe prevent this problem.

That is Steve's(Poser's) work.....on both trucks. If I had any welds that I wanted to post, I would have:frown: Working on it, though;)

yeah steve's gussetts have now inspired me to modify mine. too much point load in the center of the frame web.
