Motor mounts are not the kind of thing I expect to fail, but now that I’ve seen how my 50 year old originals look, I’d replace these as a matter of course on any old Thunderbird. I was getting a terrible clatter on right hand turns, probably the fan hitting the shroud when the engine was twisting and lifting under torque.
The mount assemblies appear to be designed to be installed on the engine block before the engine is lowered into the car. U-shaped rubber and metal insulators are attached to the block with two bolts. A 45 degree angle bracket is attached to the insulator, which provides a flat surface to rest on mounting plates on the front crossmember. A single stud on the angle bracket secures the mount assembly to the frame.
I have jackstands at their highest reach here. (I am always a little nervous being under a raised car, especially one that sits as low as the T-Bird.) With the jack and stands in place, I removed the left front wheel to get a little more room under the car.
I was not able to get the driver’s side mount out of the car with the engine jacked as high as it would go. (I removed the fan shroud to get as much lift as possible.) I removed the oil filter adapter to make room.
Some of the bolts were difficult to reach with limited room to swing a wrench. One took me a memorable two hours to get fully seated.
