How Long Do Shock Absorbers Last?

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 faster than other parts of your car.

If you have shocks that aren't working properly, it's probably time to get them replaced. You'll know if they're worn out, if your vehicle bounces around while driving or when you go over bumps in the road, the ride will feel bumpier than normal because there's not enough cushioning between the wheels and the ground.

Symptoms of Bad Shocks

Here are the symptoms of shock absorbers that are failing:

  • Hard time steering the car
  • Feeling every single bump on the road
  • Tires are wearing out faster than normal
  • Feeling like you are tilted on one side

Before it's too late, you'll want to get your shock absorbers replaced before you take a trip anywhere. Even if you are just doing errands in town, it can be dangerous at one point. How so? Bad shock absorbers can cause an accident, which is something that you do not want to get into in the near future!

If you need shock absorber replacement in the future, we invite you to bring your vehicle to Luke's Auto Service!
