While trying to remove my rear 650b. Felt it was seized, so I doused the threaded size in penetrant for a few hours. Looked like it finally started moving so I kept going until this happened.
Noticed my UDH was severely out of alignment and the washer on that side had some play.
I swapped the wheels last weekend, checked everything over, greased the axle etc. Rode a race (through some deep puddles. And here we are.
Do I have any options that involve saving this frame?

Take it to a shop. They’ll drill out the udh and thru axle threads from the drive side, then install a new hanger and axle. Also you’re missing a rotor bolt.
If you’re not comfy with drilling/hammering on your frame, take it to a reputable shop.
If you are, start by trying to get a torx (t35/40 usually close to 6mm, go as big as you can) and hammer that bad boy in. Bonus if you got a torx socket, then you can use a ratchet w/ breaker bar or breaker bar to try and get it off. If that doesn’t work, hit it with an impact wrench.
Bolt Extractors work sometimes on thru axles, but the aluminum is usually too soft in the axle and they just spin and tear things up.
Last resort is drilling it out, if you do it yourself go slow and realllllly make sure you got it straight. Drill from hangar side, if you get too froggy you ruin the hangar not the frame. Left handed drill bits are handy cause the put the torque in the loosening direction, sometimes you get lucky and the bit grabs and spins the axle out.
Like I said, If you aren’t comfy with doing some sketchy stuff, take it to a shop.
Source: work in a bike shop at a park and get stuck axles all the time. Hammering in a torx socket + impact wrench hasn’t failed me yet.
Update…
I realized after posting that since the whole head of the axle broke off that it might have released some tension. Sure enough. Was able to get the UDH off and the axle slide right out. New axle, new UDH, new anti-seize, we’ll be back in business
Thanks for your time, y’all!
