I think you kinda answered your own question. What happens to the handling of a truck on one wheel momentarily locks up...

Bearing are cheap. Just go to Avidrc.com and get new ones. They are a buck a piece. for $8 you can do all 4 wheel axles.

How are your dif beaarings? Bad bearings in there can cause all kinds of weird handleing things too. Not to mention cause alot of drivtrain drag and excess heat in the motor and esc and reduced run time.
