Kenworth T680 Drive Axle Springs & Hangers

Frequently Asked Questions About Kenworth T680 Drive Axle Springs & Hangers

What is the difference between drive axle springs and spring hangers?

Drive axle springs (leaf springs) support the weight of the truck and axle, absorbing road shock and maintaining proper ride height. Spring hangers are the mounting brackets that attach the springs to the frame, keeping the suspension securely in place. Both components work together, and wear or damage to either can affect ride quality, alignment, and overall suspension performance.

How do I know if my springs or hangers need to be replaced?

Common signs include sagging or uneven ride height, cracked or broken leaves, excessive bouncing, unusual noises over bumps, visible rust or corrosion, and cracks or elongated bolt holes on the hangers themselves. If you notice the truck pulling to one side or uneven tire wear, it is worth having the suspension inspected.

Will these parts fit my specific Kenworth T680 configuration?

Kenworth T680 trucks can be built with different axle setups and suspension packages depending on the model year and application. Before ordering, check your truck's specific axle configuration, spring capacity rating, and hanger bolt pattern against the product specifications listed for each part to confirm proper fit.

Are these springs and hangers new, remanufactured, or used take-offs?

Product condition varies by listing. Each product page specifies whether the part is new, aftermarket, or a used take-off, along with details on condition where applicable. Review the listing description and photos carefully so you know exactly what you are purchasing.

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

Replacing drive axle springs and hangers involves lifting and supporting a loaded axle, removing torque-sensitive fasteners, and ensuring correct spring alignment and ride height when reinstalled. If you have the proper lift equipment, torque specifications, and experience working on heavy-duty suspension systems, it can be done in a shop setting. If you are unsure about any part of the process, having a qualified technician handle the installation helps ensure the suspension is set up safely and correctly.
