Frequently Asked Questions About Freightliner FLC112 Steer Axle Springs & Hangers
What year models of Freightliner FLC112 are these steer axle springs and hangers compatible with?
These steer axle springs and hangers are designed to fit Freightliner FLC112 models from 1987 through 2003. However, there were minor variations in mounting configurations between early models (1987-1992) and later models (1993-2003). Always verify your specific truck's VIN and axle configuration before ordering, as some custom configurations may require different specifications.
What weight capacity should I choose for my FLC112 steer axle springs?
Standard FLC112 steer axle springs typically come in 12,000 lb, 13,200 lb, and 14,600 lb capacities. To determine the correct capacity for your truck, check the door jamb sticker for your front GAWR (Gross Axle Weight Rating) or look for stamped numbers on your existing springs. For heavy-haul applications or trucks with heavy front-mounted equipment, you may need to upgrade to a higher capacity than stock.
Can I install these springs and hangers myself, or do I need special tools?
While experienced mechanics can perform this installation, it requires heavy-duty tools including a spring compressor, torque wrench capable of 450-500 ft-lbs, and proper jack stands rated for commercial trucks. The job typically takes 4-6 hours per side. Critical safety warning: improperly compressed springs can cause serious injury. Many customers choose professional installation to ensure proper torque specifications and alignment are met.
What's the difference between OEM and aftermarket springs for my FLC112?
OEM springs are manufactured to exact factory specifications and typically use higher-grade steel alloys, resulting in better longevity but higher cost. Quality aftermarket options from manufacturers like Dayton, Hendrickson, and Triangle often provide 85-90% of OEM lifespan at 50-60% of the cost. Look for springs that meet or exceed SAE J510 standards and feature shot-peened surfaces for fatigue resistance.
How do I know when my steer axle springs and hangers need replacement?
Key indicators include: visible cracks in spring leaves, permanent sagging causing ride height loss of more than 1 inch, broken or missing spring clips, excessive rust on hangers, worn bushings causing play in the hangers, or uneven tire wear on steer tires. During pre-trip inspections, look for leaves that have shifted or separated. Replace springs in pairs to maintain proper vehicle balance and handling.
