There is a LAK12 Yahoogroup. You might ask the question there. I know that some have replaced the axle. If the drums are good, you can have the shoes re-surfaced. If you are speaking of the large fiberglass trailer, I suspect that will be your likely option. The surge linkage is mechanical. The surge trailer tongue may be serviceable, but if kept greased, would not see an issue.
