Had a minor crash and the camera arm broke. I was able to glue it back and everything moves normal. But get a gimbal overload error. Tried everything. Replaced gimbal cable, updated firmware, tried recalibration with no success. When the aircraft is off the camera rotates fine in every direction. When I power it on, it seems to stick when going up and down. Guessing I need to replace the broken part. But the only way i see to do that is replace the whole camera assembly. Camera itself seems to still work fine. Is there no way to buy the camera assembly mount instead of buying a whole new camera? Or do I have to just send it in for repair?

You can replace the gimbal if out of warranty and if your feeling brave enough but you'll still end up with an error displaying as it won't be paired with the unit fully unless officially replaced. Probably better to send it in if you're not confident with electronic repair but the choice is a personal one only you can make.  Maybe watch a couple of YT vids on it then make a decision on which route to go.
