For LiteHawk NOMAD
Remove the Lower Suspension Arm Hinge pin from the Chassis. Then remove the screw from underneath the suspension Arm holding it to the Wheel Hub.
Gently twist off the Lower Arm from the Ball socket on the Wheel Hub, and the Arm is off. To reattach the arm to the Wheel Hub, just snap it back on over the ball, don't press it on so much that it goes over the ball, it has to have freedom of movement on the ball.
Reassemble in reverse order.
