Have you been noticing that your ride has been bumpier? If so, you may want to take a look at your shock absorbers. Shock absorbers are made up of a piston, piston rod, and cylinder. The piston rod is attached to the chassis of your vehicle, while the cylinder is filled with fluid (typically nitrogen gas). When you hit a bump in the road, this causes the piston rod to move up and down within its cylinder. The movement of this piston creates pressure on both sides of it, which causes compression on one side of it (pressurized) while rarefying air on the other (less pressured). This compression/rarefaction process allows for energy absorption when driving over bumps in the road, you feel less jolting! How Long Do Shock Absorbers Last? Shock absorbers for vehicles tend to last about 50,000 miles before needing to be replaced. The reason shock absorbers have a lifespan is that they're subject to a lot of wear and tear. They have to absorb bumps in the road, so they get worn down f ... read more
