Frequently Asked Questions About Hino 238-338 Truck Leaf Springs, Hangers & Acc.
What years and models do these leaf springs fit?
Our leaf springs are designed specifically for Hino 238 and 338 series trucks manufactured from 2005 to present. This includes all cab configurations (regular, crew, and extended cab) for both models. Always verify your truck's exact year and VIN before ordering, as spring specifications can vary between early and late production years within the same model year.
Are these OEM or aftermarket leaf springs, and what's the quality difference?
We carry both OEM and heavy-duty aftermarket options. OEM springs match factory specifications exactly and typically last 150,000-200,000 miles under normal use. Our aftermarket springs are manufactured from high-grade spring steel (5160H) and often feature improved designs with additional leaves or progressive rates for better load handling. Many customers report aftermarket options lasting longer than OEM when properly maintained, especially for trucks with consistent heavy loads.
What tools and expertise do I need for installation?
Leaf spring replacement requires intermediate mechanical skills and specific tools including spring compressors, heavy-duty jack stands, torque wrenches capable of 150+ ft-lbs, and proper lifting equipment. The job typically takes 3-4 hours per side for experienced technicians. Critical safety note: Never attempt this without proper spring compressors, as springs store dangerous amounts of energy. Many customers choose professional installation, which runs $400-600 for both sides at most shops.
How do I know when my leaf springs need replacement?
Common signs include sagging ride height (measure from frame to axle and compare to specs), visible cracks or broken leaves, excessive bouncing or harsh ride, uneven tire wear, and truck leaning to one side. A quick test: measure the arch height of your springs - if they're flat or inverted when unloaded, replacement is overdue. Also check for worn bushings in spring eyes and loose U-bolts, as these often fail alongside worn springs.
What's included with the leaf springs, and what else might I need?
Individual leaf springs typically include the spring assembly with bushings pressed in. However, you'll likely need additional components for a complete job: new U-bolts (critical - never reuse), center pins, shackle kits, and spring hangers if yours show wear. We recommend our complete kit that includes all hardware. Also consider replacing shock absorbers simultaneously, as worn springs often damage shocks and new springs work best with fresh shocks.
