I had a Ford dealer put new motorcraft shocks on my 1995 Ford Explorer XLT at just over 84,000 kilometers ( just over 52,000 miles ) None of my shocks were leaking or damaged in any way , but I noticed the change right away as soon as I turned a corner . The turn in was sharper and the Explorer felt more stable . It was such a gradual decline in the performance of the original factory shock absorbers that I didn't notice

Not until the truck starts bouncing. are the shocks go to leaking.
Your air filter should be changed each time you have a oil change or perhaps a tune up which should be every 6 months.
How often should you change the fuel filter?
Electric shocks cause death in 3-15% of cases
What does your owner's manual say? I would change them if the engine is not performing as it should, you are getting poor mileage, or you have over 75,000 miles on these plugs.
Shocks should be replaced once obvious wear is noticed, such as the Suburban taking bumps in the road harder, and taking longer to recover. If the vehicle bounces after it is heavily leaned on, it is a sign the shocks are worn. Drivers who tackle rough often will need to replace shocks more frequently than those who drive regularly on highways. Most manufacturers recommend a shock replacement about every 55,000 miles.
When people get electric shocks their body often convulses.
as often as needed
Jump up and down on the back bumper. The car should not continue to bounce when you stop. You can also check the shocks from under the car, just above the read axle by the tires. Often when shocks go bad, you will see oil residue on the body of the shock.
You should change your oil every 3,000 miles. If you drive your car rough, then you should change it more often.
