2016 Trek Lexa Derailleur Hanger

Hello all, my wife has the subject bike, and her derailleur hanger has now bent 3 times in a year in a half. The last two times we took it to the shop. The most recent seems to have been caused by some rough handling by movers, but it seems like a particularly weak piece. I've never bent one, and my bike gets banged around a lot more than hers. It looks like I can get one from Wheels Mfg (number 176) that will fit. Is this something I should have no problem installing myself? Are there any specific things I should know before I try?

Bending hangers weakens them, making them more susceptible to bending again. It sounds like it's time to replace it.

So I just took off the rear wheel on the bike, and when i loosened the QR, the whole derailleur starter moving at the hanger. Initially I thought, hmm, maybe the screws on the hanger sheared or are loose. Turns out, they were never "tight" to begin with. There were simply two headless bolts going from the hanger into the unthreaded holes on the frame. I am a little miffed. This seems like something the bike shop shouldn't do. The frame itself has two spots to hold the heads of flathead screws for the hanger, but there was nothing there.

A lot to say for do-it-yourself.
