Broken Frame
Discovered today my passenger side frame rail Is fully severed. No idea how long it has been like that. Big TC's and rough roads don't mix well. Oh well, take it to a frame shop and splint it then sel...

"Unfortunately, too many couch engineers posted the "sky is falling" on this thread. There is nothing about the frame break that is not everyday repair for those that have the experience. Notice I did not say education. Engineering is great, but caution should be made. It is tough to trump years of experience. We also need to keep in mind, engineering degrees are very specific. To my knowledge, there is no engineering degree that covers every subject. Worth noting, this also applies to PHDs. I have a substantial education, but I hesitate in posting on subjects I have very little experience or education. If I do, I do state it is only an opinion."
I offer this:
With your "substantial education" as you stated, you certainly must know that a Mechanical Engineer or Architechural Engineer knows/learned or would not have graduated/received a degree if he or she does NOT understand actual structural strengths/material strengths and characteristics, design strengths and affects, structural fatigue/cracking propagation, static and dynamic loading analysis, finite analysis, structural material grain direction and material inclusions ramifications, welding and the fatigue/base material/weakness that occurs immediately next the the weld bead in steel, type of weld rod REQUIRED for various metals, pre-heating required or not, mild steel/HSLA 50-60-70-80/120-190 steels and their limitations and attributes, hydrogen embrittlement caused from improper welding rod/filler material used of arc shielding gases, etc. I could go on and on but I think you get the idea! That's what their dicipline world is all about plus so much more!
Yes, there are many forum posters who have virtually none or little real Mechanical Engineering knowledge and yet post so much garbage on subjects so far over their heads that it's almost laughable but it's not. It's not themselves they are leading astray but the unsuspecting reader and can often lead to a very dangerous outcome or failure. In 1980, Ford F series pickups got into a real frame cracking problem when they first started using HSLA (950X) as they welded their frames while another manufacturer more expensively riveted theirs. Broken welds on frame members is very serious and Ford rightfully repaired the frames that broke and mid year changed their welding methods and filler etc materials. Not all broke but the actual frame strength was well below Ford's min requirement when the loaded stressed fatigue factor reared it's ugly head. I won't name the other manufacturer's frames that experienced over 14,000 broken and/or severely cracked frames by the mid 90's due to the diesel engine torque twisting the frame rails with having well less than the manufacturer's max load specification on the truck's rear bed holding it down flat. It's researchable on the net.
