Instructions for changing motor mounts
Is it as simple as depicted here?
Instructions follow:

The motor mounts on a Ford Taurus will be located on the bottom left and right sides of the engine. The motor mounts will be secured to the top of a metal plate on each side of the frame. You will be able to see them from under the Taurus. After you have replaced the motor mounts, you will need to tighten the motor-mount securing bolts to the torque specifications for that Taurus model.
Once your Ford Taurus is on a lift, examine the upper and lower motor mounts for wear. A visual inspection, however, may not fully reveal deterioration as metal surfaces may conceal the hard rubber or polyurethane underneath that could have worn out. In all likelihood the lower motor mounts will need replacement before the upper mounts, especially if they are soaked with oil. Consider replacing all lower motor mounts at the same time.
Instructions
Things You'll Need
Jack
2 jack stands
Ratchet set
Wooden block
New motor mounts
Torque wrench
1.Raise the front end of the Ford Taurus off the ground and place the two jack stands under the frame. Lower the car onto the jack stands. Slide under the engine and place the wooden block between the engine's oil pan and the jack.
2.Raise the engine up slightly and loosen the metal securing bolts in the center of the motor mounts using the ratchet set. Remove one of the securing bolts completely and pull the motor mount from the fitting. Slide the new motor mount into the fitting and replace the bolt.
3.Repeat these steps for the opposite motor mount. Once both of the motor mounts have been replaced lower the engine. Torque the securing bolts to the specifications for that specific Ford Taurus. According to "Popular Mechanics," "Be sure to mark each old mount to indicate its direction before extracting it, then match that to the new one because there is a good chance that it can be installed 90° or 180° from its proper position, or the right one on the left side and vice versa." You will need to have a standard measure socket set and magnetic tray at the ready for removing the old mounts with new mounts available to swap. Consult your repair manual for the best way to handle this part of the job.
4.Remove the jack stands with help from the jack and lower the front end of the Ford Taurus to the ground.
Conclusion:
Once the engine mounts have been replaced, start your engine to ensure that everything is operating smoothly. This will mean that the noises you heard emanating from underneath the hood signifying a problem in the first place are now gone, the problem fixed.
************************************************** ************
Jacked up the frame on the right front and saw both mounts. Think the problem is with the rear one as you suggested. On the front one saw the nut holding the mount to the frame. Cannot see the 2 bolts holding the mount to the engine. How would I get to those 2 bolts?
For the rear mount with a bolt going thru it, How do you remove the bolt and nut and then put it back together? This mount has a large threaded part that attaches to a flange on the engine. Once again don't see where the nut holding the mount to the frame is. How do I remove it and replace it?
