after i got done driving my revo the other day, i noticed that the left side rear tire wobbles. i checked all of the other tires to see if that was just how they were made, but they have a lot less play, and the movement that they do have is front to back, while the rear tire is up and down. the truck had a lot of tumbles because i was driving it on a hill, and everytime i would crash it would cartwheel down the hill. but anyways, do i have to worry about that wheel, it isn't that bad, but i don't want to keep using it like that if it is going to wreck the rest of the machine. i only have like 6 tanks through it. hardly broken in.
