wheel bearing issues

Grrrrrr, after every event, it seems the wheel bearings get loose on the RX7. Seems crazy that they loosen every time there is an AutoX or a race. Is this common or am I and several friends trying it just incapable of seating them right? Running out of cotter pins and patience.:shrug:

It's common and it's been discussed on here. No advice other than to stock up on pins and check them after each session.
