Took my All Pro bumper (and winch) off the truck so I could plan out my tube bumper that I plan on building soon.
Discovered that the driver side frame mount was broken off on the outer most side. The pictures speak for themselves.
Welded the broken piece back on and grinded the surface smooth. Tomorrow I'm going to go down to Lowes and pick up some 1/4'' plate steel and make a new face for the frame mount (welded to the old, to increase the thickness and strength) and gusset the backside of the mounts.
Granted, I haul ass. Blitz whoops, jump the truck, etc, so I wouldn't call this typical of plate bumpers; but I wouldn't doubt if others with heavy bumpers have the same damage.
Making sure it won't happen again:
1/4'' steel brace plate welded on all four sides to the stock mounting plate.
Both sides on, welded, and painted
Can probably be attributed to stuff like this:
