I have had good success considerably extending the life of leaking strut air bags on LS400 air struts by injecting about 30 cc of Stan's Tire Sealant, www.notubes.com, through the airline fill port. Just be careful to inject the sealant fully into the core airspace of the strut using a syringe and needle, long plastic catheter even better. Getting any of the sealant in to airline could cause problems.
