On some of the very old Toyota RVs like mine you cannot unbolt the driveshaft due to the corrosion.? When I decided to unbolt mine, it took a few days with torches and solvents and different kinds of sockets and wrenches etc.? All I can say is definitely use ONLY? ?six point sockets and wrenches because I rounded off the corners of some nuts that had to be cut off.? ?It might be a good idea to pre-emtively? undo and redo
the joints in your driveshaft and other connections of your suspension.
