Hi-Ya MerkL,
You might check the motor-mounts too.
When bolted together all that stuff (engine, transmission, transfer case) is one big package supported on a tripod of mounts.
You might also want to check the anti-torque arm off the transmission. (That is, if an auto-trans 94 YJ has a anti-torque arm.)
Regards,

PS: When the Bubbacon had a broken motor-mount, I could look between the back edge of the opened hood and the tub and watch the engine roll way over and sort of oscillate while slipping the clutch away from a dead stop.
That engine roll and oscillation made the Bubba shake, rattle and roll like a golden retriever coming out of a pond.
