I would inspect all the joints carefully, if they are good, then just wait until they start showing wear. The airmatic protective bellows should be checked too but if they are good, I would not do any proactive service.

I have learned, I will believe it was a bad batch of parts when I have more than 70,000 on the new joints and they are still servicable. Until then I have to believe with so many ball joint failures it is design.

70 000 miles is a bit low for wear on good parts.
But I thought the question here was more about proactive service. Would anyone suggest changing suspension parts before any wear has been observed?
Most policy language excudes "shock absorbers." If I were looking to avoid paying a claim, I think I could make a pretty good argument that the air strut assembly, though it combines the functions of a spring and a shock into one unit, is in fact a shock absorber and therefore excluded.
Now on an exclusionary policy, I've never seen "air pump" listed as an excluded item, so I think you'd have a good shot at having an air pump replacement covered.
