I think he just wants to know how you can prove the work is actually done. Put some fingernail polish on the old one.

I had my ball joints replaced on my T-100 and it was obvious the work was done, because everything looked new. I can see on a newer vehicle it may be difficult to determine if the work was done.

Have a great New Year,
