Metal under axle snubbers

[Bretto]

I dont know if anyone ever noticed the metal thickness of the frame under theirs snubbers but on my frame, that is in great shape was really thin. I blame this on that there always is moisture in between the two. On the 2 rears, it was about 1/16" at the thinest part. I ended up filling them back up with weld and dressing it back level. Just somthing to watch out for.
