ball joint issues

Moog lists the same ball joint from '63 - '72 for both the 9" and 10" drum. They do list a different ball joint for the disc brake cars. If the failed on a 9" drum car they will fail on a 10" drum car also. Metal fatigue is metal fatigue, if it was because of this, it was irresponsible to make the comments about it like the magazine did, but then again sensationalizm is pretty commom with the media, it sells. You should almost always use the same grade bolt when replacing a bolt. Going to a heavier grade bolt can sometimes be weaker that a lower grade bolt. A higher grade bolt doesn't flex as well as lower grade and can shear or snap easier because it is more brittle.

I not try to shoot the messanger, even though it may sound like it, I just think from what I am reading about the mags comments it is a load. I am only making comments about what I have read here being I didn't read the article first hand, so maybe my comments are a load.
