Or secure your axle movement with heavy-duty torque rods (radius rods) and experience better weight distribution and on-the-road handling with replacement steer axle spring hangers for your Peterbilt truck.

Frequently Asked Questions About Peterbilt 379 Drive Axle Springs & Hangers

What do drive axle springs and hangers actually do on my Peterbilt 379?

Drive axle springs support the rear suspension and help distribute the weight of the truck and its load, while hangers are the mounting brackets that attach those springs to the frame rail. Together they keep the rear axles properly positioned, absorb road shock, and maintain consistent ride height under varying loads.

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

Common signs include sagging ride height, uneven tire wear, cracked or broken spring leaves, excessive frame or axle movement, clunking noises over bumps, and visible rust or cracks around the hanger brackets. If you notice any of these symptoms, it is a good idea to have the suspension inspected before the wear leads to further drivetrain or alignment issues.

Will these springs and hangers fit my specific Peterbilt 379 configuration?

Fitment can vary depending on axle capacity, suspension type, and the model year of your 379, so it is important to check part specifications such as spring capacity, leaf count, and hanger bolt pattern against your truck's original equipment before ordering. If you are unsure, having your VIN or current part numbers on hand will make it easier to confirm the correct match.

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

This is heavy-duty suspension work that requires proper lifting equipment, torque specifications, and safety precautions since the truck must be securely supported while the axle and springs are removed and reinstalled. Many owner-operators with mechanical experience and the right shop equipment do handle this job, but if you do not have access to a lift, jack stands rated for the axle weight, and torque wrenches, it is safer to have a qualified truck repair shop complete the installation.

What materials and finishes are available for these springs and hangers?

Drive axle springs are typically made from heat-treated steel for strength and durability, while hangers are commonly cast or forged steel components. Finish options may include raw steel, painted, or powder-coated coatings depending on the manufacturer, which can help provide additional protection against rust and corrosion in demanding on-road conditions.
