Default Longevity of Rear Suspension?

What is the average length of time rear shocks/struts/springs last on our vehicles? A few years ago, I purchased a CPO 13' A6 with 29k miles and had it for less than a month before I traded it back in for a new 16'. During the time I owned it, one of the rear shocks had to be replaced. Why it failed at 29k miles, I don't know, as I wasn't the original owner. Now the suspension in the rear of my 16' is really starting to loosen up. I'm hearing some loud clunking when I go (always slowly!) over speed bumps in my condo complex. What are others finding is the length of time that shocks/springs on the A6 (3.0T) need to be changed? For my 95' VW Jetta, it was every 30k-40k miles. For my 03' BMW 330XI it wasn't until 90k miles and I did it at that time purely for preventative reasons.

The noise sounds like it could be the hardware for the sway bars. I just replaced the shocks in my 2015 with 70,000 miles because I did not like the deterioration in the ride quality. The new shocks brought the car back to life. Springs are pretty much lifetime. When I traded in my 2005 with 142k miles it still had the original springs

FWIW my /15 A6 3.0T @ 2.5 years old / 23K miles is tight and only noise I get is over speed bumps in office parking lot when very cold out. Guessing from front struts. Wife's Volvo does same thing but my 14 year old Acura TL with 162,000 miles is silent over same speed bumps -- go figure. Lots of stuff under our A6s especially if Quattro so a bit of noise may be totally normal. As for suspension deterioration guessing depends quite a bit on road conditions and how car is driven. I would find it very disappointing despite the lousy MI roads (however I an very adept at avoiding the worst roads and most of the potholes, etc) if my A6 needed any attention in that area before 6 years or 75,000 miles.

I am waiting for the law suit where an authority is sued for car damage due to speed bumps.
Speed bumps should be illegal.

But you may live in a state with real roads and no pot holes. See why location is important?

Absolutely it is. Here in New England, the roads are horrendous. Even if you can avoid the pot holes 95% of the time, which isn't easy, in the winter or spring, the holes fill up with snow or water, and you can't see them until you hit them head on and then wonder if you just broke something. Will have dealer's service dept look a bit more carefully under there at my next oil change. I asked them to do so at last oil change, but I'd be surprised if they did..
