Shock absorbers get bashed and smashed day in and day out, so it’s no surprise they sometimes need replacing. You should check your shock absorbers and suspension every year - some vehicle manufacturers recommend replacement at around 50,000 miles. Symptoms of bad shock absorbers include a bouncy or uneven ride, banging noises or longer stopping distances. When you notice it, do something about it sooner rather than later. Replacing shock absorbers is necessary if they’ve worn out or completely failed. They’re also a good upgrade if you’re looking for a smoother ride.
