What was?
and your's was installed incorrectly.....
your weld-in brace.. it's not supposed to be welded around the whole perimeter..

if anyone would actually read the instructions, that is what is recommended... you are much more likely to have a stress riser crack when it's fully welded...
Anybody know if there is a significant difference between a 3/4 ton suburban frame ('91) and a 1/2 ton suburban? If so, what are they? I would really like to avoid something like this happening to me.
Thanks for this post - most informative

and a little snip from the link:
A couple years back my roommate was at another friends property up north. This friend has lots of Chevy trucks in various states of parted-outedness, and they decided one day to start measuring the thickness of the different frames. Here's what they came up with:
1988 1/2 ton 2wd suburban -- .162
1981 4wd Blazer ------------- .164
1987 3/4 ton 4wd suburban --- .190
1988 3/4 ton 4wd suburban --- .203
1970's unknown longbed frame- .196
1977 2wd 3/4 ton suburban --- .208
1986 3/4 4wd DIESEL longbed- .231
1979 1 ton reg cab & chasis -- .236
1984 2wd 1ton crewcab dually- .224
1982 3/4 ton reg cab longbed-- .230
I wasn't doubting anyones knowledge. It's just that I've never had to do this to any of my trucks before, (knock on wood). I'm going to do this on my Sub in a few weeks when I install my lift to prevent a cracked frame and I was planning on having it stitch welded, but I never actually heard why that would be better than a solid weld. Makes sense though.

yeah, I'm just talking out my arse.....

I wasn't implying anything with that comment, it's just this has come up so many times.... I'm not gonna get into a stress riser argument with 1/2 the forum over it... but with this product/app, I do agree with the line of thinking.. and apparently Stephen at ORD does too, and felt it important enough to put it in the instructions...
will it automatically fail if fully welded? probably not, but it does increase the chance of it failing imo...
now where'd that vertical key lime pie crust go again....![]()

Fixed. Bought the ORD weld on braces, found a local guy on Craigslist to come and weld the frame and the braces on as well as strengthen. All back on and wheeling again. Handles much better now that there is no crack.
Ready for the next issue now. People ask me why I keep fixing it, I say it only gets stronger and better everytime it breaks.
Thanks for all the input.
