Recently, my truck began making a lound banging noise as I went over speed bumps. I pulled over and investigated to find that a shock absorber had ripped its mounting bolt through the frame rail. Has anybody ever heard of this happening before?



The shock also bent itself up pretty good:



I made a patch out of 3/16ths inch plate:



Welded it in:



And the finished repair:



There was some radial outward cracking in the frame rail after the weld, as expected when welding in such small patches. I found 3 none more than 3/4 of an inch long. I stop drilled them and welded them in.
