If you have never done it before, It would be best to just remove the shaft and watch how the joint is removed and installed, by a mechanic. You can avoid damaging the new u=joint or bending the yoke. Then your problems begin. Let someone show you the how on the first one and it will be a cakewalk thereafter. Good luck.and be safe. Make sure the driveshaft has no load or pressure on it before loosening any bolts.._Ned_

Supporting the transmission while removing the cross-member is easier. You will have the engine mount holding the whole thing in precise place, while you deal with the crossmember, and the transmission.
Comparing: if you release the engine mount bolts and jack up the drive-train, the whole thing would shift, and you could have trouble when the cross-member fails to go up well enough.
On the other hand, if the cross-member bolts fail to release due to "home-mechanic" syndrome, you have only the first option.

Testimonial: "Many thanks for your input. Installation complete. Was able to raise transmission with a "jig" without releasing motor mounts or removing cross member"
The best way is to rent an engine hoist, you don't want to support the engine with a jack and a block of wood, you could crack what ever the jack is supported on, and if the engine moves, you will never get it lined up with the mount.
