Frequently Asked Questions About Freightliner SD 108-122 Steer Axle Springs-Hangers

What Freightliner models and years are compatible with SD 108-122 steer axle springs and hangers?

The SD 108-122 steer axle springs and hangers are designed for Freightliner models with severe duty (SD) specifications, typically found on FLD 112, FLD 120, Classic, and Classic XL models from 1990 through 2010. These components are specifically engineered for trucks with 12,000 to 14,600-pound front axle ratings. Always verify your truck's VIN and axle specifications before ordering, as some custom configurations may require different components.

Are aftermarket springs and hangers as durable as OEM parts?

Quality aftermarket springs and hangers can match or exceed OEM specifications when sourced from reputable manufacturers. Look for components made from high-grade spring steel with proper heat treatment and shot-peened surfaces for fatigue resistance. Premium aftermarket options often feature improved corrosion protection through e-coating or powder coating processes. The key is selecting parts that meet or exceed SAE J510 standards and carry proper load ratings for your specific application.

What tools and equipment do I need to replace steer axle springs and hangers?

Replacing steer axle springs and hangers requires heavy-duty jack stands rated for commercial vehicles, a 20-ton hydraulic jack, spring compressors, impact wrenches, and proper safety equipment. You'll need various socket sizes (typically 3/4" to 1-1/4"), pry bars, and a torque wrench capable of 450-500 ft-lbs. Many technicians recommend having a helper due to the weight of components. Always support the frame properly and never work under a truck supported only by a jack.

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

Common signs include uneven tire wear on the front axle, visible cracks or breaks in spring leaves, excessive rust or corrosion on hangers, loose or worn bushings causing clunking noises, and the truck pulling to one side. Measure your ride height regularly - a drop of more than 1 inch from specification indicates spring fatigue. During inspections, look for shiny spots on spring leaves indicating metal-to-metal contact, which signals imminent failure.

What's the difference between standard duty and severe duty springs for my Freightliner?

Severe duty (SD) springs feature additional leaf thickness, typically 0.5" to 0.625" compared to 0.375" to 0.5" for standard duty. SD springs also include more leaves in the pack (usually 8-10 versus 6-8) and use higher-grade steel alloys. The hangers for SD applications are reinforced with thicker mounting brackets and larger bushing diameters. SD components are essential for vocational trucks, heavy haulers, or any application exceeding 12,000 pounds on the front axle regularly.
