Your car’s suspension system is part of a day-to-day driving experience. It is the unsung hero in keeping you comfortable, maintaining vehicle stability, and making sure that your vehicle handles safely throughout any trip. Two of the most important elements at the heart of this are shocks and struts.
Knowing the answer to whether your car has shocks or struts will empower you to make educated repair decisions, understand what it will cost to fix them, find potential problems early, and keep your vehicle at its best. Think of the shocks and struts as the shock absorbers of the vehicle. They work hard, controlling bounce, sway, and general movement in your vehicle as you drive. Without a shock absorber, even a tiny bump would feel to those inside the vehicle like a small earthquake.
Understanding Vehicle Suspension
Your vehicle suspension system is the complex interaction of parts working in unison to provide a smooth and controlled. You would have the basic components of coil springs or leaf springs to carry the weight of your vehicle, shock absorbers or struts to dampen the blows from the road, and then there’s the mounting hardware to attach all this to the frame and the sway bars that help to control body roll during cornering.
Key Differences: Shocks Vs. Struts
Shocks are used with separate springs and mounted between the frame and axle. Their primary function is to limit spring and suspension travel, and they’re typical on trucks and some SUVs.
Struts, on the other hand, are one unit that combines spring and shock absorber. They are a structural part of the suspension system, support vehicle weight, and have a bearing inside that helps with steering. They are most typically used in today’s passenger cars.
Performance Impact
Your suspension system directly affects ride comfort, vehicle stability, steering response, tire wear patterns, and braking performance. A properly functioning suspension maintains optimum tire contact with the road, absorbs bumps, and prevents excessive body movement during acceleration, braking, and cornering. Worn-out shocks or struts can allow bouncing, swaying, and loss of vehicle control; thus, regular inspection is very important for your safety.
How to Know if Your Car Uses Shocks or Struts
It’s really quite simple to know whether your vehicle uses shocks or struts:
Visual Inspection of Control Arms
You can determine your suspension type by looking at the control arms. If you see both upper and lower control arms, your vehicle most probably has spring-seated shocks. However, if you see only the lower control arms in your vehicle, it most likely has struts.
Identifying Struts and Shocks
Struts are typically housed within the fender well and mounted directly to the steering knuckle. They contain a coil spring housing the assembly and a bearing mount on top that provides for the movement of the steering.
Shocks, on the other hand, are installed independently of the coil spring and go between the frame and axle or control arm. They can usually be visible to the naked eye looking up at the bottom of a car and are usually mounted farther back on trucks and SUVs toward the rear wheels.
Signs of Wear
Both systems may show signs of wear through a ‘bouncing’ sensation after driving over bumps, fluid leaks on the shock or strut body, unusual noises when driving over bumps, and uneven tire wear patterns.
Strut-specific signs include grinding noise during turns (worn bearing mount), clunking sounds from the front suspension, and steering wheel vibration. Shock-specific signs include tire bounce during highway driving, rear-end sway during lane changes, and excessive body roll in corners.
Location-Based Identification
Front-wheel-drive vehicles normally use struts in front and shocks in the rear, while trucks often use shocks with leaf springs in the rear. SUVs can have a combination of both systems. Be sure to check both sides of your car as some vehicles use different suspension components for front and rear.
Maintenance Tips for Shocks and Struts
Your truck’s suspension system requires regular attention to help maintain its optimum performance. When installing new shocks, compress them three times before installation to mix the gases properly and prevent rattling sounds.
Regular visual inspections should include checking for oil leakage around the shock body, damaged or deteriorating rubber boots, rust or corrosion on components, and bent or damaged mounting points.
Pay attention to warning signs such as grinding noises when turning, clunking over bumps, and squeaking from worn bearings. For performance testing, push down on each corner of your vehicle and watch for smooth recovery without bouncing, noting any differences between sides.
Remember to address any unusual noises or handling changes immediately, as small issues can quickly escalate into major problems, affecting both safety and repair costs.
When to Replace Shocks or Struts
Your vehicle’s shocks or struts should be replaced when you observe any of the following:
Noise Issues
Grinding sounds while making turns or vocalization noises while driving over bumps
Oil Leakage
Visible fluid on the shock/strut body
Age-Related Wear
Highway-driven vehicles may last between 120,000-130,000 miles
Road Condition Impact
Frequent exposure to potholes, rough roads, or dirt roads
Handling Problems
Changes in steering feel or vehicle control
Pro Tip: Replace shocks and struts in pairs. If one side is worn, the opposite side isn’t far behind. This will maintain the vehicle’s handling, weight balance, ride quality, and safety. Consider ordering complete strut assemblies for DIY replacement since they usually come with new springs, mounts, and bearings to save you both time and possible headaches while replacing them.
