Wel lfirst why is it in the ford section if its a chevy...now that thats outta the way, you have to measure and realign the carrier bearing crossmember to get the right pinion angle both from the tranny to the bearing and from the bearing to the diff. if either is off there will no doubt be a vibration in the driveline. Also the bearing is set at an angle from the factory to properly align the Ujoint and driveshat and give them the right angle for optimun performance.
