Should I replace the struts or just the shock?
When it comes to maintaining your vehicle's suspension system, understanding the difference between struts and shocks is crucial. Both components play vital roles in ensuring a smooth ride and maintaining vehicle stability. However, knowing when to replace one or both can save you time and money in the long run. In this article, we will explore the functions of struts and shocks, signs that indicate a need for replacement, and the considerations you should make when deciding whether to replace just the shocks or the entire strut assembly.
Understanding Struts and Shocks
Struts and shocks are both part of your vehicle's suspension system, but they serve different purposes:
- Struts: Struts are a structural component of the suspension system. They provide support for the vehicle's weight and help maintain alignment. Struts also contain a shock absorber within them, which means they perform the functions of both components.
- Shocks: Shock absorbers, on the other hand, are designed solely to dampen the impact of bumps and vibrations. They help control the movement of the springs and keep the tires in contact with the road.
Signs You Need to Replace Struts or Shocks
There are several indicators that may suggest it's time to replace your struts or shocks:
- Excessive bouncing: If your vehicle bounces excessively after hitting a bump, it may indicate worn shocks or struts.
- Uneven tire wear: If you notice uneven wear on your tires, it could be a sign of suspension issues, including worn struts.
- Fluid leaks: If you see oil or fluid leaking from the shock or strut, it’s a clear sign that they need to be replaced.
- Noise: Clunking or rattling noises when driving over bumps can indicate worn struts or shocks.
Should You Replace Just the Shocks or the Struts?
Deciding whether to replace just the shocks or the entire strut assembly depends on several factors:
- Condition of the components: If your shocks are worn but the struts are still in good condition, you may only need to replace the shocks. However, if the struts show signs of wear, it’s advisable to replace both.
- Cost considerations: Replacing struts can be more expensive than replacing shocks. If budget is a concern, you might consider replacing only the shocks if they are the primary issue.
- Age of the vehicle: If your vehicle has high mileage, it may be more cost-effective to replace both struts and shocks at the same time to avoid future repairs.
Conclusion
In summary, whether to replace just the shocks or the struts depends on the condition of each component and your vehicle's overall performance. Regular inspections and maintenance can help you identify issues early, ensuring a safer and more comfortable driving experience. If you're unsure, it's always best to consult with a professional mechanic who can assess your vehicle's suspension system and provide tailored advice.
Frequently Asked Questions
What happens if you don't replace struts?
Reduced Handling and Stability: Struts help maintain tire contact with the road. Worn struts can cause poor handling, making the vehicle harder to control, especially during turns or on uneven surfaces.
How do I know if I need new shocks or struts?
Excess dipping and bouncing when you hit the brakes or go over a bump are good signs your shocks/struts need to be replaced. If you hear squeaking when you go over bumps they may also need to be replaced. If you see oil leaking from the shocks/struts they definitely need to be replaced.
What else should be replaced when replacing struts?
Yes, it is also a good idea to replace both the strut mount and the strut boot when replacing struts. The strut mount optimizes suspension performance by providing a smooth steering response and reducing vibration.
Should I replace the whole strut or just the shock?
Shocks and struts should always be replaced in pairs or, better yet, all four, for even, predictable handling and control.
When replacing struts what else should be replaced?
Yes, it is also a good idea to replace both the strut mount and the strut boot when replacing struts. The strut mount optimizes suspension performance by providing a smooth steering response and reducing vibration.
Do you need an alignment after replacing struts?
Monroe ® recommends performing an alignment anytime struts or other steering and suspension components are replaced. Failure to make sure the vehicle's alignment is within factory specifications can lead to problems like premature tire wear and other customer comebacks.
Is it OK to drive with bad struts?
Once the wear starts hampering your vehicle's performance, your service provider will likely recommend replacing the worn part to restore your car's ride and handling. If you choose to wait to inspect worn shocks and struts, you jeopardize your ability to stop, steer and maintain stability.
What is the lifespan of a strut?
50,000 to 100,000 miles
Shocks and Struts Lifespan
However, they typically last from 50,000 to 100,000 miles. Refer to your owner's manual for specific maintenance schedules.
Can I replace shocks without replacing struts?
In most cases, you cannot replace just the shock absorber in a strut assembly. Struts typically consist of several components, including the shock absorber, coil spring, strut mount, and various bushings. When a strut fails, it is generally recommended to replace the entire strut assembly for several reasons:
What are the symptoms of a bad strut?
Read on to learn the signs of worn shocks & struts:
- Nose dive when braking.
- Bouncy ride.
- Vehicle rolls or sways when cornering.
- Uneven tire wear.
- Rear squat during acceleration.
- Vibration in steering wheel.
- Unusual noises.
- Leaking fluid on exterior of shocks/struts.
