Ha! Friends dads Ford pickup did that, he was revving it at a light and the balancer came off and hauled *** across the street into a curb and shattered! Funny as all hell as he was showing off at us across the intersection.
I lost an allen wrench, I guess I laid it in the enginebay and it bounced a few times under the car at 60mph until it exited stage rear. Wife about died as we were in the sticks....low on gas too.
