Freightliner FL70-FL80 Drive Axle Springs-Hangers

Frequently Asked Questions About Freightliner FL70-FL80 Drive Axle Springs-Hangers

What components are included in this category?

This category covers drive axle suspension components for Freightliner FL70 and FL80 models, including leaf springs, spring hangers, spring seats, U-bolts, bushings, and related mounting hardware that support the rear drive axle assembly and connect it to the truck frame.

How do I know if a spring or hanger is compatible with my FL70 or FL80?

Compatibility depends on your truck's exact model year, axle configuration, and original suspension setup, since Freightliner used different spring capacities and hanger designs across production years. Always check part numbers against your VIN or existing components, and reach out to our parts specialists if you are unsure before placing an order.

What signs indicate a spring or hanger needs to be replaced?

Common warning signs include visible cracks or rust-through on the spring leaves, a sagging or uneven ride height, cracked or worn hanger brackets, excessive cab or axle movement over bumps, and unusual clunking noises when braking or turning. Any of these issues should be inspected and addressed promptly to avoid further drivetrain or alignment problems.

Are these springs and hangers new, remanufactured, or used parts?

Availability varies by listing, and each product page specifies whether the part is new, remanufactured, or a quality used component. Be sure to review the condition details and any included warranty information on the specific listing before purchasing.

Do I need professional installation for drive axle springs and hangers?

Replacing drive axle springs and hangers involves lifting and supporting the truck, removing torque from the suspension, and precise torquing of U-bolts and mounting hardware, so this job is typically best handled by an experienced diesel or heavy-truck technician. Improper installation can affect ride height, alignment, and load distribution, so professional installation is strongly recommended.
