    Hi Larry,

    Sorry to learn this, but thanks for the update. Many on this forum will be following your progress on getting this resolved. I guess there is a downside to having a tow vehicle so strong and stable that you did not even feel an impact of this magnitude. I would think that the front axle (and maybe even the rear one) should be on the “to be replaced” list.

      chattacuda Good solution on the IS install. They install a sub-frame that will beef this all up.

I'll let the pics tell the story but the short version is I obviously hit something. It appears the front axle hit so hard the axle itself contacted the frame and the tire hit the tire well and distorted it. The frame I beam above the front axle is bowed inwards about 1/2". The back tire contacted the fender well slightly also. I have a mess on my hands. I have to straighten the I beam enough to get it to Morryde in January for the IS install. Ughh. I will keep you all posted.
        Larry,

        From your pics this does not look to bad. Your frame is designed with positive camber built in so the string should normally not follow the flange overall. The yielded section would be worse since its rolled over. Also its not hard to get into tire to floor contact where there is minimal space there normally. A few years ago many of us were having floor contact which resulted in a change in spring rate along with other improvements. But that's another story.

          Thanks Jim I was just reading about the built in camber last night. I suppose I will compare it to the other side to see how much to straighten it out. I have been reading a lot of engineering articles about flame straightening beams which is where I am going to start. If you stay under 1050 F is will not affect the strength of the material.

          Take care and thanks again!

            Thanks Rob. I will update as time goes on I am donating the axles to the Morryde scrap pile when I get the IS installed in January!

              chattacuda You are probably not going to want to hear this, but straightening the lower flange on the I beam is not going to be easy unless you are willing to cut the flange or replace a section of the frame. The inner side is most likely stretched and the outer side is double bent. You can try to get the bends on the outer side straightened and that may help get it straight.

              When you do get it straight, you may want to put a longitudinal plate above the hangers at about a 45 between the flange and the web. My 2 pervious campers had this to help with the hanger loadings into the flanges. They only use short pieces and tack weld them in place, however if I were doing it, I'd go the full length of the axle hanger spread plus some to help spread out the forces.

              Good luck with the repairs. Look forward to seeing your progress and results.

                  We used to do the same thing to straighten race car axle tubes that had been tweaked while "rubbin". I was amazed at the simplicity of finding the tweak and the cure.

                    Thanks all. I have used flame straightening on big shafts before and am familiar withn the science behind it, which is why I said that is how I plan to straighten the bowed in section of the I beam. The twisted center hanger part I will straighten with heat and force. I am getting all my tooling together now and I still need to roll back the mid section of the coroplast. The more I look at it and the existu=ibng cross braces the more convinced I am I can fix it back right. Time is critical since it is cold here now and I have to have it back on the road by Jan 4 for the trip to Elkhart Jan 4 for the IS upgrade.
