How long should rear air shocks last before leaking oil? on 2003 Buick LeSabre

One rear shock has oil leaking, but air suspension does not seem to be a problem. When I had tires replaced, I was told that I had a leaking shock. I had previously seen that while replacing brake pads, so I have a pair of the shocks. If I wait to replace them, will the air compressor for these air shocks also need replacing?

50k is the recommended time for shock/strut replacements from the manufacturer.

Between 50k-70k depending on driving habits
If the shocks air not leaking air the compressor should be fine the only time thay truly fail is when people let the shocks leak air for a long amount of time which causes compressor to have to over work.
