when the has a frontal crash , the chasiss bends and compress front to back , shaft play avoid the bevel gears to push the diffgears
pretty sure considering ive used the TB-02 in GT2 and GT3 for 3 years now at Tamiya's TCS series. I think i was the only one with a TB-02 at nationals last year. anyways.. you dont want to shim it tight. just enough play so that you can have a piece of paper inbetween. kind of like your spur/pinion gear mesh. same idea.

evo3 had the same problem. the original shaft was too short. tamiya made running fixes to try to cure the problem (reinforced, fatter one way gear and longer shafts with a thicker front end) thus the TB-02 inherited the defects.
