Frequently Asked Questions About Freightliner Cascadia 116/126 Steer Axle Springs

What years and models of Cascadia are these steer axle springs compatible with?

These steer axle springs are designed specifically for Freightliner Cascadia models 116 and 126 from model years 2008 through 2024. They fit both day cab and sleeper configurations. However, compatibility can vary based on your truck's specific front axle weight rating (12,000 lb, 12,500 lb, or 13,200 lb configurations). We recommend verifying your VIN and front axle specifications before ordering to ensure proper fitment.

Are these springs difficult to install, and what tools do I need?

Installation requires professional-grade equipment and experience. You'll need a heavy-duty spring compressor, proper jack stands rated for commercial vehicles, and standard hand tools. The job typically takes 3-4 hours per side for experienced technicians. Many customers report that attempting DIY installation without proper equipment is dangerous. We strongly recommend professional installation, as improper spring installation can lead to serious safety issues and premature component failure.

What's the difference between OEM and aftermarket springs, and how long do they typically last?

OEM springs are manufactured to exact Freightliner specifications and typically last 300,000-500,000 miles under normal highway conditions. Quality aftermarket options use similar spring steel grades and heat treatment processes, offering comparable lifespan at a lower price point. Heavy-duty aftermarket springs may actually exceed OEM durability for severe-duty applications. Look for springs made from SAE 5160 or 9260 spring steel with proper shot-peening treatment for maximum longevity.

How do I know when my steer axle springs need replacement?

Common signs include uneven tire wear on the front axle, visible cracks or breaks in the spring leaves, permanent sagging that affects ride height (measure from axle center to frame rail), excessive bouncing or porpoising while driving, and metal-on-metal contact between spring leaves. If your truck pulls to one side or you notice a difference in ride height between left and right sides, immediate inspection is recommended. Most DOT inspections will flag springs with any visible cracks or broken leaves.

Do these springs come with new bushings and hardware, or do I need to order those separately?

Most steer axle spring sets are sold as springs only and do not include bushings, U-bolts, or mounting hardware. You'll typically need to order spring eye bushings, shackle bushings, U-bolts, and center pins separately. We recommend replacing all bushings and hardware during spring replacement to ensure proper alignment and prevent premature wear. Complete hardware kits are available that include all necessary components for both sides of the front axle.
