prob. with zip again
 

i am having a problem with my zip again..i got a "high speed gear set" for microsizers, but now my car goes badly to the left. i had another microsizer gear set on before that and it when straight. i ajusted the little white thing the other way and it still turn hard to the left when going straight. The axel has alittle play side to side while on the car...does that have anything to do with it? thanks:D

did you check under the magnet...there may be some kind of metal dust that builds up

Are you using the same tires? If one tire on the rear axel had more grip it would pull right or left. Maybe try new or different tires, and switch sides to see what happens.

Sometimes the wheels will slip on the axle. Grab hold of one wheel and see if you can spin the other wheel, if so this could also be the problem.

what happened to me was i pulled my gears off my microsizer 2 fast and 2 furiouse (haha) but ne way in the process i bent the axle without me knowing and when i put it on mi other microsizer it wouldnt go straight. thats probably what happened to you. try taking the axle off with the tires still on it then roll it on a desk and see if its all funky looking. one of the wheels should wobble. if thats the case your done with it. if u bend it back u will most likely bend it at the wrong spot making it worse so dont waste your time.
