Peterbilt 587 Steer Axle Springs & Hangers

Frequently Asked Questions About Peterbilt 587 Steer Axle Springs & Hangers

What is included in this category?

This category covers the front steer axle leaf springs and the spring hangers (also called spring brackets) that mount the springs to the frame rails on the Peterbilt 587. These components work together to support the front axle, absorb road shock, and maintain proper steering geometry.

Will these springs and hangers fit my specific Peterbilt 587?

Steer axle springs and hangers can vary by GVWR rating, axle capacity, and build date, so it is important to match the part number to your truck's specifications rather than relying on model year alone. Check your VIN or existing part numbers, or contact our parts specialists to confirm fitment before ordering.

How do I know if my steer axle spring or hanger needs to be replaced?

Common signs include visible cracks or sagging in the leaf spring, uneven ride height from side to side, excessive cab or front-end vibration, clunking noises over bumps, and cracked or worn hanger brackets or bushings. A qualified technician should inspect the front suspension if you notice any of these symptoms, since worn components can affect steering control and tire wear.

What materials are these springs and hangers made from, and does that affect durability?

Steer axle leaf springs are typically made from heat-treated alloy steel for strength and fatigue resistance, while hangers are usually cast or forged steel designed to handle repeated stress and vibration. Higher-quality steel and proper heat treatment generally translate to longer service life, especially for trucks running heavy front-end loads or rough terrain.

Is installation something I can do myself, or should a professional handle it?

Replacing steer axle springs and hangers involves supporting and lifting the front axle, removing torque-loaded fasteners, and precisely realigning suspension components, which affects steering and handling. Because of the safety implications and the need for proper torque specs and alignment checks afterward, this job is best performed by an experienced diesel technician or at a qualified truck repair shop.
