A Quick Guide To Car Suspension

When you hit the road in your Orlando Toyota, it’s typically pretty comfortable for you in the driver’s seat. You don’t feel every bump or dip in the road and can kick back, relax, and focus on the road ahead of you… all thanks to your car suspension. But how does your car suspension work and positively impact your drive time? Toyota of Orlando is here with answers.

What does car suspension do?

Basically, your car suspension “suspends” your car off the ground. However, it’s a little deeper than that – here are some of the main functions of car suspension:

• It absorbs vibrations, impact forces, and shock from the ground. When you drive, the road can cause your tires (and subsequently your car) to vibrate and jolt. Your suspension absorbs these movements to ensure you’re more comfortable in the driver’s seat.
• It keeps your car tires in contact with the road. Your car’s axles and wheels are connected to your car suspension system and basically, your suspension system keeps the tires on the road by pushing them down (especially when the road is bumpy – without car suspension, your tires would constantly be flying off the ground).

So not only does your car suspension ensure your drive time is comfortable, but it also keeps you safer by ensuring your tires have constant contact and traction on the road.

How does car suspension work?

There are two basic types of car suspension: dependent and independent.

Dependent suspension (or beam axle) is a super simple design and cheaper to produce. However, it’s not very common – the tires are dependent on one another to move, so if one stops moving, it impacts the others. This reduces traction and makes the vehicle less safe. (It’s great for off-roading, though.)

Independent suspension allows all of the tires to move independently of one another. If one loses traction or lifts off the ground, the other tires aren’t impacted, making this a safer option for everyday drivers.

The parts of car suspension explained

Your car suspension is composed of springs, shock absorbers, dampers, struts, and sway bars. Here’s a brief overview of what each of them does.

Springs: Springs basically let your car bounce so it can handle irregularities in the road; they also help to support any extra weight in the car. Finally, they keep your car at one predetermined height. There are three types of springs – coil, leaf, and torsion bars.

Dampers: Dampers help absorb the energy from the springs so they don’t continue to bounce. Think about it – if you go over a bump, the springs bounce and will continue to bounce unless something absorbs that energy. Enter your dampers. Dampers include shock absorbers, struts, and sway bars.

• Shock absorbers: Shock absorbers slow down your car’s springs and also reduce the magnitude of the vibrations by converting this kinetic energy into thermal energy, which is then dissipated by hydraulic fluid.
• Struts: Struts are similar to shock absorbers and serve a similar function, but are mounted inside of a coil spring.
• Anti-sway bars: Also known as sway bars, these metal rods join opposing car suspension systems to provide more stability and keep your car level even on bumpy surfaces.

Frequently Asked Questions

What does a car’s suspension system do?

A vehicle’s suspension system is designed to absorb bumps and maintain stability while driving. It helps keep your tires in contact with the road, improving handling, comfort, and overall safety.

What are the main components of a car suspension system?

Key suspension components include shocks or struts, springs, control arms, and sway bars. Each part works together to support the vehicle’s weight, reduce impact from the road, and ensure a smooth, controlled ride.

What are common signs of suspension problems?

Common signs include a rough or bouncy ride, uneven tire wear, drifting or pulling when turning, and unusual noises when driving over bumps. If you notice any of these issues, it’s important to have your suspension inspected promptly.

Shocks vs struts: What to know

People come in pretty routinely with questions about shocks and struts. Here are a few key differences to remember:

Struts are the combination of a shock and spring assembly in one unit. They’re a heavy-duty part, and they’re attached to the wheels. Their main purposes are to soften your ride, hold the tire in place, and assist the steering system.

Shocks are located right behind your tires and are mounted next to the springs. Their one job is to prevent the car from bouncing as you drive down the road.

When your struts or shocks go bad – which they will as they eventually wear out over time – you need to replace them. Failing to replace worn-out struts or shocks can result in a tire blowout, a broken steering system, and other (expensive) parts failing. Here are some signs you should look out for on your Orlando Toyota:

• You find leaking fluid on the outside of the shocks or struts
• The vehicle “tips” to one side when you’re making turns
• When you hit the brakes hard, the front end of your car dips down significantly
• Contrastingly, when you hit the gas hard, the back end of your car dips down significantly
• Instability at highway speeds (70 mph+)
• Your tires bounce excessively after hitting a bump in the road
• Your tires wearing unevenly because they’re bouncing on the road a lot

And it’s a good idea to troubleshoot your car suspension as a whole routinely. Here are some signs your suspension is having issues and you need to schedule an appointment at Toyota of Orlando‘s service center:

• You hear clunking or thunking noises when you hit a bump
• Your drive time feels bumpier than usual like you can feel imperfections in the road more
• You have difficulty steering
• You feel your car drifting or pulling to one side when you turn corners
• You notice that one side of your car is sitting lower than the other when parked
