Classic Mini Rubber Ball Joint Dust Cover Sold as a Pair BTA377-SetA
Dust cover for all four swivel pin joints.
Sold as a Pair
The same part is used on uppers or lowers.
This dust cover does get neglected but it does a tough job where it is positioned in keeping out the debris from the joint.
If ever you are working on the car or adjusting the joints and have a chance to change these they should be renewed as they are not expensive.
