It is all supposed to be clamped solid, and the rubber itself will move.
If the bar moves against the rubber, it will wear down exactly as you 
have described! It is always the harder material that wears (such as a 
camshaft in an aluminium head) because the softer material "absorbs' the 
abrasive particles.
I think Polybushes work on a different principle, and they DO need
