Plenty of DIY instructions on the net, I'm sure; Bentley manual is also helpful. The biggest hassle with this job is getting the exhaust off, with all its decade-old rusty fasteners. Get new manifold flange gasket and new copper nuts and be prepared to use a torch to heat the old nuts to get them off without breaking the studs in manifold. At the rear, figure out whether it is easier to drop the exhaust bracket from the body or leave it there and drop the exhaust from the bracket, depending on what part has the most rusted fasteners. Remember to mark the two parts of the driveshaft for re-assembly alignment and to pre-load the new center bearing mount slightly forward from its free position.
