On a basic level, friction results in wear.
Grease reduces friction, unfortunately the Morgan design doesn't allow the grease to remain in place but it does allows dirt and moisture to enter the bearing surfaces.
Vesconite has a lower co efficient of friction than bronze and is also self-lubricating.
Other synthetic materials are available.
As Morgan seem reluctant to change the fundamental design of the front suspension they could at least better engineer it to increase longevity and reduce maintenance.
