I found out a way to make your wheels wobble less and turn better using tape. I used really sticky tape for this. i cut some strips the size you need to put on the little plastic thing that makes your wheel turn that sticks out and the sides of the yellow bar with things sticking out. putting tape on the thing that makes your car turn and the sides of the yellow bar will make your parts turn without being loose and without wobbling action. don't put to much tape because the moving parts will be to tight. sorry for not being specific. i dont know what the names are.
