ok, after this i am doing a total idiot check on my entire truck...last time there was a loose connection to my ignition coil that was causeing it not to run...now the front end bounce was solved by tightening all the lug nuts(which was only 3 per tire) I got replacements for the missing nuts and it has not bounced since, even on the road that would always make it do bounce...the lug nuts were on so loosly that i needed no force at all to remove them...the previous owner of this truck must have neglected common sense check ups throughout his ownership
