hi i have built a running 4wheel atv with front wheel problems. when i'm riding at full throttle the front wheels want to jerk left and right real hard,so what would be the problem for it doing that and how do i fix it. ANY AND ALL ANSWERS WE BE HELPFUL




THANKS

Terrain and tires come to mind as well as front wheel alignment just off the top of my head.

do both tie rods need to be same length?

Of course.

also could it be my steering system because there is no resistance in the system. meaning that its a very loose turning but tight spindle system.
