when to replace shocks and struts

Normally, you have to keep a check on some factors. These factors can give you the signal when to change shocks and struts. Jerky driving, Leaking fluid, the late response of brakes are a few of them. Why don’t we explore and know more? This is not gonna be bumpy!

8 Factors to Know When to Replace Shocks and Struts

Well, your suspension won’t wear out in a flash. Shocks and struts take time to deteriorate.

Now, to figure out how to tell when you need new shocks? That is the million-dollar question to find an answer to this question, you have to check on some factors.

Factor 1: Rough Ride

Roads can be as bumpy as trampolines.

Actually, to avoid such unpleasant bounces, shocks and struts are used. The more they get damaged, the more bounces your car gets.

If this jerking continues and you find yourself mid-air often in the car, you should change your shocks and struts.

Factor2: Fluid leakage

Hydraulic fluid works in the shock to absorb the impacts.

If there’s a shortage of fluid in shock, the shock may fail to work properly. If you spot any leakage of fluid around the shock, you might have to exchange your shock and struts.

Factor-3: Unusual Tire Pattern

Unusual patterns on your tire mean something’s fishy.

Damaged suspension causes a cupping effect. You will notice a scalloped dip over the treadwear of your tire. You have to change your shocks and struts then.

Factor-4: Measuring Mileage

Cars generally require shocks and struts replacement after 50,000 miles of driving.

You can actually predict the replacement time. Before the shocks and struts start showing problems, you can easily change them without any problems.

Fator-5: Damaged Struts

When to replace struts? You can see the damaged struts yourself.

After continuous use, struts and shocks get damaged.

Sometimes this damage can be physically visible. Mark this physical damage and replace it accordingly.

Now you have your answer, right?

Factor-6: Vehicle Losing Control

As shocks and struts wear out, the Performance of the suspension system decreases. As a result, you will face unusual factors:

  • Poor response of the steering.
  • Unable to handle car’s weight distribution.
  • Taking more to stop than usual.
  • Failure of the brake.
  • Excessive body lean.

If you see these issues, get ready to change your shocks and struts.

Factor-7: Rise of the Front End

Seeing that the front end of your car rises while accelerating?

This happens during hard acceleration. The rear end of your car squats basically.

If so, then don’t hesitate and change your shocks and struts.

Factor-8: Sound of Shocks and Struts

You can check out what do bad shocks sound like.

Your car will make many types of noise. This means it’s time for your shocks to retire.

Knocking Type Noise

Suppose you’ve hit a speed breaker or hole in the road and your car made a ‘bump’ noise.

Voila! Your shocks need a break. The spring bounces against the chassis of your car. That’s what creates the noise.

Squeaky Hinge Noise

You can hear some squeaky old door-opening noise in your vehicle.

Don’t worry. You are not in a horror movie. It’s just a bad ball joint of your suspension, giving you a signal to replace your shocks.

Rattling Noise

You can identify bad shock by rattling sounds as well.

You can check your suspension then. However, rattling noise can happen for many reasons. Could be an actual rattlesnake in your car!

Thus, to specify, you need to carry on other tests as well.

Groaning Noise

When there’s something between your steel mechanism and shocks, you will hear groaning noises. This means that you have to give a visit to your suspension.

Keep one thing in mind. Noises can be heard in many cases. So look for other symptoms than just noise.
