Kenworth Cabover Drive Axle Springs & Hangers

Frequently Asked Questions About Kenworth Cabover Drive Axle Springs & Hangers

What components are included in this category?

This category covers the suspension components that support and locate the drive axles on Kenworth cabover trucks, including leaf springs, spring hangers, spring seats, U-bolts, bushings, and related mounting hardware. These parts work together to carry axle load, absorb road shock, and keep the drive axle properly positioned under the frame.

How do I know these springs and hangers will fit my specific Kenworth cabover model?

Kenworth cabover models such as the K100 and T600/T800 predecessors used different frame widths, spring capacities, and hanger mounting configurations depending on the model year and axle setup. Always confirm your truck's model, year, and axle rating against the part number or fitment chart before ordering, and compare hanger bolt patterns and spring dimensions to your existing components to ensure a correct match.

What is the difference between a spring hanger and a spring seat, and do I need both?

The spring hanger is the bracket that mounts to the frame and holds the end of the leaf spring in place, while the spring seat sits on the axle and cradles the spring pack from below. Both parts serve different functions in the suspension assembly, so if one is worn or cracked, it's worth inspecting the other since they experience similar stress and wear over time.

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

Common signs of worn springs include sagging ride height, uneven load distribution, cracked or broken leaves, and unusual noise over bumps. Hangers should be inspected for cracks, elongated bolt holes, rust-through, or looseness at the frame mounting points. If you notice any of these issues, replacement is generally recommended over repair since these are structural, load-bearing components.

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

Replacing drive axle springs and hangers involves supporting significant vehicle weight, working with torque specifications, and ensuring proper alignment of the suspension and axle, so this job is typically best handled by an experienced technician with the right lifting equipment and tools. If you have the proper shop setup and mechanical experience, self-installation is possible, but improper installation can affect handling, tire wear, and safety.
