Hino 238-338 Truck Drive Axle Springs & Hangers

Frequently Asked Questions About Hino 238-338 Truck Drive Axle Springs & Hangers

What do drive axle springs and hangers actually do on my Hino 238/338?

The drive axle springs (leaf springs) support the weight of the truck and cargo over the drive axle while absorbing road shock, and the hangers are the mounting brackets that anchor the spring assembly to the frame. Together they keep the axle properly positioned, maintain ride height, and help distribute load evenly across the suspension.

How do I know if I need new springs, new hangers, or both?

Common signs include sagging or uneven ride height, cracked or shifted leaves, excessive bouncing or sway, unusual clunking noises over bumps, and visible rust, cracks, or wear at the hanger mounting points. If the hangers are cracked, bent, or worn at the pivot bushings, replacing them along with the springs is usually recommended since a worn hanger can cause premature spring wear even after new springs are installed.

Will these springs and hangers fit both the Hino 238 and 338 models, or do I need to check specific years?

Parts listed in this category are built to fit the Hino 238 and 338 chassis, but axle capacity, spring configuration, and hanger design can vary by model year and specific truck build. Before ordering, check your truck's GVWR, axle type, and existing spring/hanger part numbers, or contact our parts team to confirm fitment for your specific VIN or configuration.

Are these springs and hangers made from OEM-grade materials, and what finish do they come in?

Our drive axle springs and hangers are manufactured to match OEM specifications for material strength and load capacity. Hangers are typically cast or formed steel with a protective coating or paint finish to help resist corrosion, while springs are heat-treated steel leaves designed for the load ratings of the Hino 238/338 platform. Always confirm the specific finish and material listed on the individual product page, as options can vary by supplier.

Can I install drive axle springs and hangers myself, or should I have a shop do it?

Replacing leaf springs and hangers involves supporting and lifting the truck safely, removing u-bolts, spring pins, and bushings under load, and properly torquing all fasteners to spec afterward. This is a heavy, safety-critical job that requires proper lift equipment and torque specifications, so unless you have experience with heavy-duty suspension work and the right shop equipment, we recommend having a qualified commercial truck technician handle the installation.
