Gear clicking

Alright so I got everything in to the ruckus 4x4. Mod 1 gears. With a castle creation motor but it clicks on acceleration and breaking worried something is wrong. Any ideas?

First thought would be to check your gear mesh @ruckus4x4project

And after that? I checked the mesh it seems good can fit a peice of paper through it like it should. Is it naturally a loud car?
