Freightliner Century 112/120 Drive Axle Springs

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

What is included in this category - are these leaf springs, hangers, or both?

This category covers drive axle suspension components for the Freightliner Century 112/120, including leaf springs and the hangers/brackets that mount them to the frame. Depending on the specific listing, you may find leaf spring assemblies, individual leaves, spring hangers, and related mounting hardware used in the rear suspension system.

How do I know these springs and hangers will fit my specific Freightliner Century truck?

Fit can vary based on the truck's model year, suspension type, and axle configuration, even within the Century 112/120 line. Before ordering, check your truck's VIN and existing suspension setup against the part number or fitment notes listed on the product page. If you're unsure, our sales team can help confirm compatibility using your VIN or the part number from your current spring or hanger.

Should I replace drive axle springs and hangers in pairs or all at once?

Many technicians recommend replacing springs in pairs (both sides of an axle) to maintain even ride height and load distribution, especially if the springs show similar wear or age. Hangers are typically replaced only when cracked, worn, or damaged, but it's worth inspecting both sides while you're already doing the work to avoid a repeat repair down the road.

What condition are these parts in - new, used, or reconditioned?

Product condition varies by listing, so check each product page carefully for details on whether the part is new, used, or reconditioned. Used parts are typically inspected for cracks, excessive wear, and structural integrity before being listed for sale, but we recommend a thorough visual inspection on your end as well before installation.

Do I need a professional to install drive axle springs and hangers, or can I do it myself?

Replacing leaf springs and hangers involves lifting and supporting a heavy truck, removing torque-loaded fasteners, and properly aligning suspension components, so this job is generally best handled by an experienced technician with the right tools and lift equipment. Improper installation can affect ride height, alignment, and handling, so if you're not confident in your ability to safely complete the repair, having a professional shop handle it is the safer choice.
