Ball and trunnion boot replacement
I've been told, but never installed one over mine yet, that the V/W Beetle Swing Axle Boot will install over it our A-body Ball & Trunion. May have even been on this site. It is a split boot not requiring dis-assembly.
One day I'll get around to dropping $20 for one and giving it a try.
If you try this, let me know how it works out.
