The only real awkward mount is the rear mount.
You can tell if a mount needs to be replaced by:
-the engine is sagging to one side
-there is a lot of engine/transmission movement when load is put through the engine
-the mount is physically cracked or ripped
-the mount has bottomed out.
If its a hydraulic mount, which I'm 95% sure you do not have, you can also see it leaking fluid.
