Sterling A-Series Steer Axle Springs- Hangers

Frequently Asked Questions About Sterling A-Series Steer Axle Springs- Hangers

What components are included in this category?

This category covers front steer axle leaf springs and the spring hangers (also called spring brackets) that mount those springs to the frame rails on Sterling A-Series trucks. These parts work together to support the front axle, absorb road shock, and maintain proper ride height and alignment.

How do I know if a spring or hanger will fit my specific Sterling A-Series truck?

Fit can vary by model year, cab configuration, and front axle weight rating (GAWR), so it's important to match the part number to your truck's specifications rather than relying on the model name alone. Check your truck's VIN or axle tag information, and compare it against the part listing details or reach out to our parts team to confirm compatibility before ordering.

What are the signs that my steer axle spring or hanger needs to be replaced?

Common warning signs include uneven ride height, a sagging front end, cracked or broken leaves, excessive cab vibration, clunking noises over bumps, and uneven tire wear. Cracked or elongated hanger mounting holes, rust-through, or visible metal fatigue on the hanger itself are also signs that replacement is needed rather than repair.

Can I replace just one spring or hanger, or should they be replaced in pairs?

While it's technically possible to replace a single damaged spring or hanger, most experienced technicians recommend replacing both sides at the same time. This helps maintain even ride height, consistent spring rate side to side, and balanced handling, especially if the components are original and have significant mileage or age.

What should I expect during installation, and is this a job I can do myself?

Replacing steer axle springs and hangers involves supporting the front axle safely, removing U-bolts and mounting hardware, and torquing new components to the manufacturer's specified values. This job requires proper lifting equipment, torque wrenches, and a solid understanding of front axle suspension systems, so it's often best handled by an experienced diesel technician or fleet maintenance shop unless you have the right tools and experience working on heavy-duty steer axles.
