From Pathfinder Wiki
Put the axle in at a downward (5-10 degrees) angle. This provides two benefits. The first is that only the inside edge of the wheel is in contact with the track. This seems to make the car go straighter with less wobble. The second benefit is that the wheel rides to the outside of the axle and doesn’t come in contact with the body. This tip is for experts only. First timers have trouble getting this right.
