Kenworth T700 Drive Axle Springs & Hangers

Frequently Asked Questions About Kenworth T700 Drive Axle Springs & Hangers

What is the difference between drive axle springs and spring hangers, and do I need both?

Drive axle springs (leaf springs) support the weight of the truck and axle while absorbing road shock, while spring hangers are the brackets that mount the springs to the frame. If your hangers are cracked, bent, or worn from age and vibration, they should be replaced along with or independently of the springs. Many customers replace hangers when they notice unusual play in the suspension or uneven ride height, even if the springs themselves are still in good condition.

Will these springs and hangers fit my Kenworth T700 regardless of axle configuration?

Fitment can vary based on your truck's specific axle setup, spring capacity rating, and whether it has a single or tandem drive axle configuration. Before ordering, check your truck's build sheet or existing part numbers to confirm the correct spring rating and hanger style for your application. If you're unsure, our team can help you cross-reference your VIN or existing parts to find a compatible match.

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

Common signs include sagging ride height, uneven tire wear, a rough or bouncy ride, visible cracks or rust on the springs, or looseness in the hanger bushings. Clunking noises over bumps or when accelerating can also indicate worn hangers or bushings. If you notice any of these symptoms, it's worth having your suspension inspected before the issue affects handling or causes additional wear to other components.

What material and finish options are available for these parts?

Drive axle springs are typically made from heat-treated steel to handle heavy loads and repeated flexing, while hangers are usually cast or forged steel for durability under constant stress. Finish options may include raw steel, painted, or coated surfaces depending on the manufacturer, which can affect corrosion resistance in different climates or road conditions. Check the product listing for specific finish details before purchasing.

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

Replacing drive axle springs and hangers involves working with heavy components under load and often requires specialized tools like a spring compressor, along with proper lifting and support equipment. Because incorrect installation can affect ride height, alignment, and safe handling of the truck, this job is generally best left to an experienced technician or fleet maintenance shop unless you have the right equipment and experience with heavy-duty suspension work.
