Extension Housing: Service and Repair
On some models, it is necessary to unload both torsion bars and drop one side of torsion bar crossmember to provide clearance for extension housing
removal.
1. Mark parts for reassembly and remove propeller shaft.
2. Remove speedometer pinion and adapter assembly, then drain about two quarts of fluid from transmission.
3. Remove extension housing to crossmember bolts, then raise transmission with jack and remove crossmember.
4. Remove extension housing to transmission bolts. On console shift models, remove torque shaft lower bracket to extension housing bolts.

or engaged with the parking lock sprag.
