Squeaky problem with squeaky air strut sleeves!

I have chassis tech front air strut sleeves on my 99 passat and lately during suspension travel,I get this horrible wallowing sound,like a hurt whale or somthing.Is the bag rubbin on the metal of the sleeve or do I need to lubricate somthing??

sounds like your shock is screwed

see,I considered that option but their riding fine,nice and smooth caddy like ride.
