Never heard - don't want to hear a bike moan. The '90 Volvo's dry rubber sway bushings moan when entering, but ensure ball suspension are greased.
Other than the eyelet separating from the Honda's rear shock, the shock still retained compression (??psi), just not attached to the swing arm. If the relay is dry, riding may (temporarily) stop any moaning by grinding rust crystals (that grew while idle) into powder. Replacing the FeO2 with 2 cents worth of molybdoenum disulfide may save a lot of moaning over a trailer rescue / repair estimate.
