A friend has a '92 Toyota Camry and the rubber inside the upper engine mount ("dogbone") is cracked.
It looks to me like it's a simple procedure: just remove two bolts, replace the mount, and replace the two bolts. It doesn't look to me like the mount is actually supporting the engine at rest.
Is that correct, or should we support the engine from below (e.g., via a board on a small jack under the oil pan) when replacing this mount? Thanks in advance.

The dogbone mount is replaced simply by unbolting it and bolting in the new one. You don't need to jack the engine up. Pay attention to the offset of it's strut so that the new one goes in with the same offset. If you are unsure, try laying the new part in both ways; one way the mount will look slightly twisted in it's brackets, the other way it will look straight. It is a subtle difference. I have seen cars come in that had this put on backwards, though I would think it would be fairly obvious if you pay attention during installation.
This dogbone mount can simply tear from normal engine rocking motion, but it will wear very quickly if your front engine mount is worn. The front mounts on 92-96 Camrys are really bad for breaking, too. It would be wise for you to replace it as well, but it is more difficult. You must jack up the engine during the process. There are three 10mm bolts on the bottom flange and one 12mm nut on the top stud that require removal, then the engine has to be lifted enough to provide clearance for mount removal.
