Not sure if this is well known in "rustville" but just an FYI. My tailgate hinges on my 00 Sierra were rusted out and causing the tailgate to rattle around a bit and also sag a little on one side when lowering it. Both the pins that are on each side of the bed and the "receivers" on the tailgate are easily replaced. Each piece is held on by 2 bolts. Pulling the tail light assemblies allows access to the threaded parts of the bolts for pb blaster or another penetrating lube before removal, if needed. The bolts on the tailgate itself seemed to not be rusted at all and came right out. Aftermarket hinge kit is 20-25 bucks at your local parts store!
