They are sealed units unfortunatly. Rubber bag is vulcanised to base. Looks like coat is a none starter.

My old dunlop OEM airbags fit to the base just like a tyre to a rim, so I would think they can become unseated, but it sounds like the bags are shot from your description as when the bag comes away from the base, you do not get bubbles as there is no pressure at all!

Are you sure Data, the ones i removed from the rear of mine a few months ago looked pretty well stuck on there with something other than good will. Surley if they were just forced over a boss to sit in a undercut, on full extension, unlike a tyre were the are pressure forces the tyre into contact with the rim, pressure would force the bag out of the undercut. Unless it was bonded to it. If i still have my old ones i'll put them through the band saw and have a look.

One of mine actually popped off, also I have seen just the bladders for sale to fit to old parts. I think they stay put because they fold under which means the inner part of the fold is pressed against the base. I didn't like the look of them so I bought Arnott Gen 2's which are crimped.

Ok you are correct, had a look around and found a Aussie bloke who advertises just the tubes. You live and learn.
