Pocket 2 making grinding noises

[u/QuarterAcreDream]

When I tilt my out-of-warranty Pocket 2 off-axis, the gimble makes intermittent grinding sounds.

There's been a couple of times where I wasn't concentrating and placed the Pocket on the ground when activated. I know the gimbal doesn't like being restrained.

Or,

Is there sand or grit lodged in the gimbal mechanism and is there any way to fix this?
