R U S T
It's everywhere on my truck. One example: The hitch mount bolts broke off inside my frame when I was puting the new rear bumper on. I had to chisel off the weld nuts in the frame rails and slide in some metal bar with new weld nuts inside the frame rails to install it.
The front is OK because of leaking oil and steering fluid. Haha But the back of the truck all the fasteners are really rusted everywhere. I always get nervous about servicing components back there.
*edit* Another example, when I took off the side step mounting brackets, I had 2 of the captive nuts inside the body break free and spin and another bolt or two that just broke but without breaking the captive nut.
Sad to hear but this level of rust is not a common problem for most
