RE: Drive Shaft Install
The factory manual calls for lowering the fuel tank. Then you unbolt the driveshaft flange to remove the driveshaft. This is another job I hired out due to the fact it required dropping the exhaust as well and I refuse to work on the exhaust.
I've been told one of the easier ways is to lower the differential housing and slide the driveshaft out the rear and to the side of the center section. Depending upon your exhaust, it may also need to be lowered.
