Frequently Asked Questions About Freightliner Century 112/120 Drive Axle Springs

What are the weight capacity ratings for Century 112/120 drive axle springs?

The standard drive axle springs for Freightliner Century 112/120 models typically support between 20,000 to 23,000 pounds per axle, depending on your specific configuration. Heavy-duty applications may require springs rated up to 26,000 pounds. Always verify your truck's GAWR (Gross Axle Weight Rating) on the door jamb sticker or VIN plate before selecting replacement springs to ensure proper load capacity.

Will these springs fit my specific year Century truck?

These drive axle springs are compatible with Freightliner Century Class 112 and 120 models manufactured from 1996 through 2010. However, there are variations based on suspension type (Freightliner AirLiner, Hendrickson, or Reyco). Check your existing spring pack for the OEM part number or measure the spring dimensions - standard lengths are typically 54 inches with varying arch heights from 3.5 to 5 inches depending on your suspension setup.

Do I need special tools or professional installation for spring replacement?

Spring replacement requires heavy-duty equipment including spring compressors, proper jack stands rated for commercial vehicles, and impact tools. The job typically takes 4-6 hours per axle for experienced mechanics. Due to the extreme forces involved and safety concerns, we strongly recommend professional installation. Improper installation can lead to premature wear, handling issues, or catastrophic failure.

What's the difference between OEM and aftermarket spring options?

OEM springs use original manufacturer specifications and materials, typically featuring shot-peened leaves for longevity and precise spring rates. Quality aftermarket options often match or exceed OEM specs at a lower price point, using similar high-carbon steel construction. Look for springs that meet SAE J510 standards. Avoid budget options that use recycled steel or skip the shot-peening process, as these typically fail within 50,000-75,000 miles versus 150,000+ for quality springs.

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

Replace springs when you notice: visible cracks or breaks in any leaf, separation between leaves, permanent sagging causing the truck to sit lower on one side, excessive bounce or poor ride quality, or U-bolt marks that have worn deep grooves into the spring pack. Uneven tire wear on drive axles often indicates spring issues. As a preventive measure, inspect springs every 50,000 miles or during regular PM services, paying special attention to the main leaf and spring eyes for stress cracks.
