Fitting the mount to older Jeeps
Early Jeep transmissions such as the T90 and T86 sat on a crossmember that carried most of the drivetrain weight, and a rubber mount there works as a cushion between the gearbox and the frame. On these older vehicles the rubber often hardens and splits, which lets the transmission rock during shifts and transmits more engine vibration to the cabin. Because the mount is one of several drivetrain supports, a worn cushion can also strain the shifter linkage and nearby exhaust hangers.
Before installing a new mount, look at the crossmember for rust, cracks and enlarged bolt holes, since an old frame bracket can make a new mount sit at an angle. Remove the old mount with the transmission supported, and clean the bolt threads before reassembly. Many restorers replace the rear mounts and crossmember bushings at the same time, so the drivetrain sits evenly. After a few drives, check the fasteners again, because rubber can settle as it takes the load.
