You'll have to loosen up the front differential and slide it foward. Then remove the bolt holding the U-joint to the thru shaft. Then slide the driveline apart and re-install the boot on the removed half. Then when you re-install the driveline you then install the other half of the boot on the part of the driveline that is on the differential. Then re-install the driveline and differential and go ride.
