Is it the Bellows that are leaking , or where the Bellows sit ,often there is a leak either between the top plate its connected too or leaks around the pston where the airbag moves up and down on ? if so when air bag is removed ,(fairly easy job ,Switch off engine apply Handbrake ,chock wheels that are not being removed , remove one end of shock absorber fault side (both sides if jacking up both sides of vehicle) jack up Chassis high placing / adjusting support / safety stands as you jack up chassis .
Drain out air if need be , sometimes airbag gets stuck to mounting plate or piston , after removeing bag if leak was at top check top plate for rust holes and get it welded up , we used to have leaks on 17 and 24 tonne trucks and found if airbag was not holed we removed airbag checked top mounting and piston for hole . if no holes cleaned up rust from bag and from piston and plate ( now this you may think is a bodge ,probaly is ! but it works apply flexible gasket cement to top plate and piston if they are a bit rough ,reassemble.
Please, please don't attempt this repair if you are not competant , p.s. If it's actually the air bag go round motor factors ,or , breakers yard but check for cracks if seconhand .
if you don't understand above PM me
