Sustain rods

[Ron Nossaman]

Robin,

I can't imagine the rod is bent. I'd check not only the hanger brackets, but the hangers too. I've found loose or broken ones. If the dampers lift in a uniform wave from the lever end first, try bending the hanger(s) nearest the lever out a bit (gently).
If you need a quick and dirty on a piano you don't feel warrants much time, it's worth a try. If you do try this though, be prepared to replace broken hangers when you find the cracked one(s).

Luck, Ron Nossaman
