When it comes to your vehicle’s suspension system, two key components often get mentioned: shocks and struts. While many people use these terms interchangeably, they’re actually quite different — and both are critical to keeping your ride smooth, safe, and in control on Calgary’s ever-changing roads.
Whether you’re navigating icy winter streets, spring potholes, or gravel backroads outside the city, understanding the difference between shocks and struts can help you maintain your vehicle better — and know when it’s time to get them checked or replaced.
What Do Shock Absorbers Do?
Shock absorbers (or simply “shocks”) are designed to control the bounce and rebound of your vehicle’s springs and suspension. When you hit a bump or dip, the shock absorber helps dampen the movement, keeping your tires in contact with the road.
Without shocks, your vehicle would continue bouncing after every bump — making for an uncomfortable and potentially dangerous ride.
Components of a Shock Absorber
Shock absorbers are hydraulic devices. They contain:
- A piston inside a tube filled with fluid
- Valves that regulate how fast the fluid moves
- A mounting system to connect to the suspension and chassis
When your wheels move up and down, the shock resists that motion by pushing fluid through the piston, slowing the movement and stabilizing the ride.
What Do Struts Do?
Struts do everything a shock does — plus more. A strut is a structural part of your suspension system and is usually integrated with a coil spring. It supports the weight of your vehicle and plays a role in steering and alignment.
Think of struts as a shock absorber with extra responsibilities. That’s why they tend to be more expensive to replace.
Components of a Strut
A typical strut includes:
- A shock absorber (built-in)
- A coil spring to support weight and absorb big impacts
- A strut mount that connects to the vehicle frame
- A bearing plate that allows the strut to rotate for steering (in front struts)
Because struts do more than shocks, wear or failure can seriously affect vehicle handling.
How Many Shocks or Struts Does My Vehicle Have – and Where Are They Located?
Most vehicles have either shocks or struts on each wheel — not both. A common setup:
- Front-wheel drive cars: Struts in the front, shocks in the rear
- Trucks and SUVs: Often shocks on all four wheels, or a combination
You can usually find this info in your owner’s manual — or better yet, ask our technicians at Urban Lube Calgary for a quick inspection.
Common Signs of Worn Shocks and Struts
Wondering if it’s time for replacements? Here are the telltale signs:
- Bumpy or rough ride
- Nose diving when braking
- Excessive body roll when turning
- Uneven tire wear
- Leaking fluid around shocks or struts
- Increased stopping distance
- Knocking noises when driving over bumps
If you’re noticing any of these symptoms, it’s time to get your suspension checked.
Why Are Shocks and Struts Important for Your Vehicle’s Safety?
Shocks and struts are crucial for:
- Vehicle control
- Braking efficiency
- Tire longevity
- Ride comfort
Worn shocks and struts don’t just make your drive uncomfortable — they make it unsafe, especially in Calgary’s wintery or slick road conditions.
How Shocks and Struts Impact Driving in Calgary’s Conditions
Calgary drivers face unique challenges: sudden snowfalls, icy intersections, and bumpy backroads. Shocks and struts are your first defense against losing control in these situations.
Good suspension:
- Improves traction on icy roads
- Reduces bouncing on gravel or pothole-ridden streets
- Maintains alignment even after tough weather or off-road adventures
If you’re hitting the mountains, driving rural roads, or commuting year-round, your suspension system needs to be in top shape.
When Should You Replace Shocks or Struts?
Most experts recommend replacing shocks or struts around 80,000 km to 100,000 km, depending on driving conditions. But in Calgary, where roads and weather can be rougher, you might need to do it sooner.
If your ride feels off, don’t wait. A quick inspection can prevent bigger (and more expensive) problems down the road.
