Ball & Trunnion

U-joints fail, I've never heard of or saw a b&t that failed.
Most, the boot cracks, that's all, remove it, clean up the internals, new grease and boot.

I wouldn't even attempt to r&r the pin.

I bought a boot that is for something else entirely, it is an exact match except it is a little long, just trim it and it is identical.
