i have a 99 f 350 xcsb that when driving at highway speed and im not on the gas or brake kinda in a neautral zone it vibrates it turns out to be play up and down out of the transfer case and the extender joint joint towards the rear end. i know that that has a different name but i cant remeber. is there anyway of fixing this issue before i break something and not buying a new driveshaft? it dosent have a carrier bearing setup.the rubber boot around the joint that holds the grease in is ripped so its wore out thanks
