my mini-baja is making crunchy sounds when it accelerates. what do i need to adjust/fix? is my differential shot?

it might just be gear mesh, but still could be your diff. hold one wheel and turn the other. if it feels like a bowl of cornflakes then its shot. if it does feel like breakfast, oiling it again may help.

I checked the pinion / spur gear mesh with a piece of paper and it seems good. There is no visible sign of damage there. No real noise when I turn the wheels, and it doesn't seem like the diff is loose or anything. Do you just open the gearbox and differential to look for visible damage there? I've never opened it before. Also could the slipper clutch make popping / clicking noises?

A clicking or crunching sound could be your diff gears. Just open up the gear box slowly and check the diff gears. If they are chewed up your diff is history.
