Peterbilt 587 Drive Axle Springs & Hangers

Frequently Asked Questions About Peterbilt 587 Drive Axle Springs & Hangers

What do drive axle springs and hangers do on my Peterbilt 587?

Drive axle springs support the weight of the truck and cargo while absorbing road shock, and the hangers are the mounting brackets that secure the springs to the frame. Together they keep the rear suspension properly aligned, help maintain ride height, and ensure consistent handling and load distribution.

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, visible rust or corrosion on hangers, unusual clunking or squeaking noises over bumps, and difficulty keeping the truck aligned. If you notice any of these symptoms, it is a good idea to have your suspension inspected before continuing to run the truck under load.

Will these springs and hangers fit my specific Peterbilt 587 configuration?

Fitment can vary based on axle type, suspension configuration, and model year, so it is important to check part numbers and specifications carefully against your truck's build sheet or existing components before ordering. If you are unsure, our team can help confirm compatibility using your VIN or current part numbers.

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

While some experienced fleet mechanics do replace springs and hangers themselves, this job typically requires specialized tools, proper lifting equipment, and knowledge of correct torque specs and alignment procedures. Because these components are critical to safe handling and load support, we recommend having the installation performed by a qualified technician.

What material and finish options are available for these parts?

Drive axle springs and hangers in this category are typically constructed from heavy duty steel designed to handle the stresses of daily hauling. Finish options may include options like painted or coated surfaces to help resist rust and corrosion, extending the service life of the components in demanding on road conditions.
