Is it possible to purchase the gimbal mount and install it myself? My warranty period is over, just wondering if possible.

Hi there, Mavic Pro Gimbal mount is not available to be purchased from DJI authorized channels, and we do not recommend customers to repair on their own in case more issues happen. It is recommended to send back to DJI official repair center or the recommended repair center for assistance: https://www.dji.com/service/repair?site=brandsite&from=footer

you tube it.  2 screws in the lower cap where the gimble cover snaps on and then only 4- 1.5 MM hex bolts holdine the gimble in and the whole thing comes out.
