The portion of a yoke that gets "tweaked" by misshandleing is the thin tube the cylinder spins on. The most infamous way they get bent is from closing the cylinder with a flip of the wrist. A bent tube can be straightened with gunsmith tools. In your 1st picture you might be pushing hard enough to flex that tube. You are putting an abnormal stress on the system. I never tried that. In your second picture showing the 629 in its normal at rest state it looks healthy. I suspect what the 629 needs is less examination and more target shooting. While I'm not a gunsmith I can recommend an iron bullet mold and set of reloading dies. To get comments from gunsmiths put your pictures in a new thread in the Smith-Wesson-smithing sub-forum. However, before starting the thread brace yourself for some harsh handling instructions.
