Struts usually get a good run for 120k-160k pushing the envelope. Having the need of strut replacement at 240k is to be expected, as Well as tie rod ends, and alignment.

The manufactures claim struts last for approx. 50,000 to 60,000 miles.
But it depends on where you live, the driving conditions, your driving habits and the year and make of a vehicle.

Struts deteriorate gradually but typically 60,000 miles or so.

That's a lot of miles on original struts. Usually depends on how & where you're driving. You can test them yourself & see how they react to your weight on them, or you can take a look and see if they're moist or greasy.

Most strut manufacturer's will tell you 40-80,000 miles. At 240,000 you might be better off doing quick struts as the springs tend to get weaker with higher mileage.
