Jack up the car...start grabbing stuff and shaking it. Which part(s) is loose?

U-joint on the driveshaft can exhibit clunks during initial engagement from neutral/reverse to forward direction. Very common replacement on my 4x4 truck. Easy enough test and/or replacement. Not sure on durability of half shaft u-joints.
