It is hard to say exactly what damage you are doing to your car, IF, it is the motor mounts. Failed motor mounts usually allow an extra 3-5" of engine travel. While most of the hoses, cables and wires have some slack for engine movement, they could get pinched or rub up against something repeatedly enough to wear off the insulation.
The biggest factor that is hard to determine is that engine and transmission alignment in relation to the sub frame and other components is imports. Angles as well as distance and sometimes motors will sit unevenly. This wears out components like axles, it can wear the brackets that hold your motor mounts and I have seen in extreme cases where the engine was sitting on the sub frame and the angle damaged the block.
So, I can't tell you exactly what is happening, only give you an idea of the importance of proper engine alignment and vibration/isolation is to many large components.
So, driving the car easier will help. When you hit potholes it hurts and all you can do is purchase the mounts and replace them.
It is generally not hard to do. I tried to find the location of the motor mounts, but they are generally in common places;
On transverse or sideways mounted engines;
There is a mount on the lower front
There is a mount on both ends
There is a mount on the rear which attaches to the sub frame
There is a mount on the transmission either on top or the back or front of the transmission. This one you have to hunt down. If you buy the mounts you can usually find them by looking at the new ones and looking for the like part.
On in-line mounted engines;
There is a mount on both sides
There is a transmission mount on the rear cross member that supports the rear of the transmission
While I was looking for this information, Ford did have a note in bold letters saying, "The driveline angle of the drive shaft is critical to components prematurely wearing and getting damaged. This is especially true of universal joints." I am assuming you have an in-line ounted engine, where the accessories are in the front of the motor. This will also put strain on the differentials.
So, it is important to replace them all ASAP.
Look on-line for the best deals. Try thefind. Com, but beware of web sites that are, "thrown together" and unprofessional looking with prices to good to be true. Expect to pay around $50 per mount give or take $20. If you have an in-line motor you only need 3 and transverse require 5, but are cheaper. Rockauto. Com is a good place for closeout sales and usautoparts. Com is also good.
Gets those mounts replaced because $200.00 in maintenance will save $2000.00 in repair.
