A book or story that is currently contemporary would be aware that Bush is president, that people are dying in a war in Iraq that has been going on for some time and that American Idol is influencing music being played on CD's or by downloads.
But just how long can your expect these tailbone-saving gadgets to last? The short answer? Experts recommend replacing shocks every 50,000 miles (80,467 kilometers), but a great deal depends on how you treat your vehicle's suspension. Are you logging all those miles on the placid interstate, or are you off-roading on winding dirt roads through the untamed wild?
Shock absorbers are attached to the vehicle body and suspension components. They are used to absorb road shock, providing a smooth ride. Most cars made after 1995 have shock absorbers in the back wheels and strut assembly in the front. Older cars and trucks may have shock absorbers at all four wheels. Shock absorbers are basically cylindrical containers filled with gas or liquid.
