One should take care not to bend the driveshaft more than 25 degrees, and it is preferable to hold the two parts straight with a holding fixture, which can be a piece of 2x4 of the right size with wooden blocks on one end. When there is no available support that holds up the driveshaft in a level plane, a floor jack or assistance would be used. Today, there are no spare parts of the driveshaft, and in case such components as
CV Joint, U-joint, or center support bearing are damaged, the whole drive shaft has to be changed; it is advisable to hire a specialist on the driveline to get advice on the possible repair. One should start by raising the vehicle safely on jackstands and then take off the back part of the exhaust system. Peel off and remove the front rivets/mounting fasteners of the heat shield, one side of the mounting fastener at a time and align the center support bearing bracket tabs with the center of the outer holes of the floor pan. Align the relationship between the CV joints and flanges and clamp each end of the driveshaft and loosen the bolts that fix the CV joints to the companion flanges, avoiding the rotation with a chain wrench. Then detach the fasteners connecting the center support bearing bracket to the floorpan, and any shims and record their locations and then take pains to lower and remove the driveshaft underlying the vehicle. Removal should be reversed, so it is necessary to install fresh gasket material and remove old CV joint bolts and install new ones, install new gaskets, replace the heat shield (which dropped out of place) and install any shims in their correct places. Prior to installing the center support with the bracket fasteners, ensure that the centering tabs are aligned with the holes on the outer floorpan, and new sheet metal rivets/clips are fitted on the heat shield front mounting holes, and lastly, tight all the fasteners accordingly to the recommended torque values.
