I've recently noticed as I park my '92 Sovereign at night in the quiet of my garage that there appears top be a faint clicking sound from underneath the rear end. It's a very rapid as if something is settling gradually. Is this normal for the suspension or am I looking at a big expense, I'm assuming it's the self leveling system, but maybe I'm way off , advice/help please, all welcome, thanks, Paul.
