What type of grease are you using?

EDIT: Here is the appearance of a completely messed up gearbox, no grease for an entire build season.

Bingo. We had both our toughboxes fail in 2010 because the original grease was cheap garbage. After nearly 100 matches it had turned solid and metal was the only lubricant that we had.

We now regrease before each competition. It's easy because there are holes that allow you to do so on the gearbox without opening it up! Just fill the sucker and tape over the holes.
