Well, typically Series III bushings get chewed up in 20-30,000 miles of normal US driving - but that was with the original "rubbish rubber" from Metalastik.
Trucks and SUVs tend to have larger, sturdier bushings, so they wear out as a matter of time, not mileage. The same holds true for some of the larger cars sold here. Usually, though, it's not the suspension bushings that go on US market cars, it's the ball joints, shocks, struts and suchlike. The recommendation on replacing shocks, for example, is every 50-60K or less. Balljoints get shocked, bent and broken by potholes; tie rods too. Toyota and others have had issues with potholes punching out strut mounts of late, too. I'd say I've had to replace more hard parts than bushings on my cars over the years, and I get about 50K out of a set of suspension components, on average.
Thinking about it, it's a wonder we don't have *more* suspension failures on US market cars.
