1997 Lincoln Continental Front strut bearings

The Moog part number for the upper strut mount is K80030. The design and replacement procedure is the same as on any other car with struts.

The bearing is part of the upper strut mount. It is never available separately. The mount IS available by itself. I suspect you're thinking you have to buy the complete strut, spring, and mount as an assembly, but that is the less-common way of buying the parts. Those complete assemblies eliminate the need for a spring compressor, and the new springs restore proper ride height which restores balanced braking front-to-rear, and improves steering control and handling.

Regardless of whether you replace just the mount or the whole assembly, the car needs to be aligned after the repairs are completed.

You're right. I did find just the bearing for a Windstar but not the Taurus. That suggests they have a lot of trouble with them. As a professional suspension and alignment specialist, I would never do that to my customers. It's the metal mounting plate that usually rusts away and puts debris in the bearing assembly. Replacing just the bearing is like buying a new pair of shoes but using your old shoe laces over to save a few cents in the short term. A repeat failure in a year would not make for a happy car owner and it wouldn't boost my reputation for doing quality work.

Also, the metal sleeve in the center of the mount usually breaks away from the rubber and makes a rattling noise as the strut shaft moves sideways. On some car models that rubber shrinks over time and lets the top of the shaft bounce up and down. While that in itself isn't a major safety issue, it can make the car sound like it's about to fly apart.
