Minnesota winters are notoriously harsh, bringing not only frigid temperatures and snow but also hazardous driving conditions for commercial truck fleets. For drivers and fleet managers, preparing for the season isn't just about swapping out tires or topping off fluids—it's about ensuring that every truck's suspension system is ready to handle the stress of winter roads. At Fleet Alignment Service, we know that your trucks are the backbone of your business, and their safety is paramount when the weather turns.

The Crucial Role of Suspension in Winter

Your truck's suspension does far more than provide a comfortable ride. It is central to how your vehicle handles corners, absorbs road imperfections, and maintains traction—all of which become even more critical in icy, snowy, or slushy conditions. A poorly maintained suspension system can cause uneven tire wear, reduce steering control, and increase stopping distances, particularly when traction is already compromised.

Statistics from the Federal Motor Carrier Safety Administration (FMCSA) show that poor vehicle maintenance, including issues with suspension, is a significant contributor to commercial vehicle accidents, especially in challenging weather conditions. The stakes are simply too high to ignore suspension health as winter approaches.

Inspecting Shocks and Struts

Shocks and struts are at the heart of your suspension system, keeping your tires in contact with the road and absorbing the bumps and jolts from potholes—many of which are hidden beneath layers of snow or ice during a Minnesota winter. If these components are worn or leaking, you may notice increased bouncing, nose-diving during braking, or swaying on curves. These problems are not just uncomfortable—they're dangerous when road conditions are slick.

As temperatures drop, the hydraulic fluid inside shocks and struts can thicken, making any existing wear even more pronounced. If you see fluid leaks around these parts or hear complaints from drivers about handling, it's time for a replacement. Ensuring your shocks and struts are in top shape helps maintain even tire wear, which is essential for safe winter traction.

Springs and Bushings: Don't Overlook the Details

While shocks and struts get much of the attention, springs and bushings are equally vital. Springs bear the weight of your truck and its cargo, while bushings provide a cushion between suspension components. Cold weather can make bushings brittle and prone to cracking, while springs can sag or snap under stress—problems that are only exacerbated by the constant freeze-thaw cycles and salt exposure common in Minnesota.

A thorough inspection should include checking springs for sagging or rust and bushings for any visible signs of wear or damage. Unusual sounds such as squeaks or clunks during travel are often the earliest warnings that something is amiss.

Control Arms, Ball Joints, and Alignment

Control arms and ball joints connect the suspension to the wheels and steering, allowing for smooth movement and precise control. Winter brings moisture and road salt, both of which accelerate corrosion and wear on these parts. Regular lubrication and inspections can prevent premature wear and ensure your truck maintains correct steering geometry.

Proper wheel alignment is another crucial factor. Misalignment causes uneven tire wear, reduces fuel efficiency, and makes it harder to control your truck—especially hazardous on slippery winter roads. That's why it's important to have your trucks professionally aligned after any significant impact or at the start of the season. At Fleet Alignment Service, we use advanced alignment technology to keep your trucks running straight and true, minimizing the risk of winter mishaps.

Building a Winter-Ready Suspension Checklist

To stay ahead of winter breakdowns, create a detailed suspension checklist for your fleet. Start with a visual inspection, looking for:

• Oil leaks around shocks and struts
• Cracked or damaged rubber bushings
• Rust or corrosion on springs, control arms, and mounting points
• Unusual noises during operation or when turning

Encourage your drivers to report any changes in ride quality or handling immediately. Addressing small issues early can prevent them from becoming costly repairs down the road.

Safe Winter Driving Habits Protect Your Suspension

Even the best-maintained suspension system can only do so much if winter driving habits are lacking. Encourage your drivers to reduce their speed, avoid sudden steering or braking, and keep a safe distance from other vehicles. According to the Minnesota Department of Transportation, winter road conditions are responsible for a significant increase in accidents from December through March, with most incidents occurring during or just after snowfall.

Drivers should also avoid potholes when possible, as hitting one at high speed can immediately damage suspension components. Remind your team that reporting new bumps, noises, or steering issues after encountering rough roads is critical to fleet safety.

The Value of Professional Suspension Inspections

While daily walk-arounds and attentive driving are important, nothing replaces a professional suspension inspection. At Fleet Alignment Service, our technicians use advanced diagnostic tools to identify hidden wear, assess alignment, and recommend any necessary repairs or adjustments. Regular professional inspections—especially before and during the winter months—can save your business from unexpected downtime and costly repairs, all while keeping your drivers and cargo safe.
