Colombo, funny I was reading about this problem last night on the Forest River forum under Dynamax. It seems that this Freightliner Service Bulletin is dated Sept 2010 and Freightliner is still using the older designed parts.
Within the Forest River posting some folks have just replaced the bushing and moved on.
I just checked my bayonet bushings, the lower ones look ok, the top ones are dried-out, hardened, like toast. I guess I will be visiting our local Freightliner service center.
