Trail damage...is derailleur salvageable?

[David Bonnell]

After a ride, the derailleur was angled inwards, the cause being a
bent derailleur hanger.
I pulled the 'railer, straightened the hanger, cleaned everything up
and reassembled. The derailleur suffered no obvious damage...pulleys
are parallel to the cassette cogs, nothing seems to be bent.

Unfortunately, I couldn't get the system to shift reliably. There
seems to be lateral play when manually moving the cage/pulleys (as if
the mechanism is looser than it should be). I tried another
derailleur and had no problems with shifting.

Is there any chance this derailleur is salvageable, or should I just
throw it out? It is an Alivio with that bizarre Shimano Megapulley.

I don't think it's worth fussing with, since a replacement is not only
cheap, but apparently you already have one lying around.

it's cheap garbage. throw it out and get a new [better] one.
