Got all of the shackles (8) replaced yesterday with the help of a local mobile RV repair.
All were worn and a couple more were close to going.
I'm assuming, after talking to a local Spring shop, and your post etex211, that it is just a normal part of wear and tear after 13k miles this summer, some of it on pretty rough roads.
Hoping for no more major breakdowns on our last 1500 miles home.
If anyone is ever in Dawson Creek BC (250-782-1136) and needs suspension help, I can highly recommend United Spring. The owner called me back yesterday (I'd left a VM because they were closed for holiday) and came and looked at my problem, took me down to his shop and opened up and fixed me up with parts.
