Well lets see....First pull the driveshaft.
2. Pull the speedo cable
3. Jack transmission up and remove the transmission mount
4. You may want to remove the crossmember, if you want for access.
5. Unbolt the tailshaft housing, 6 bolts if I remember.
6. Remove tailhousing.
7. Remove rear seal and bushing, replace seal and bushing
8. Replace gasket for tailhousing.
9. Install everything is reverse order.
