Ford F-350 Super Duty Leaf Spring Bushings
Ford F-350 Super Duty Leaf spring bushings
Leaf spring bushings for your Ford F-350 Super Duty start at $18.95, with 6 options in stock from MOOG, Mevotech Original Grade, and Mevotech Supreme. These rubber or polyurethane sleeves cushion the mounting points where leaf springs attach to the frame and axle, isolating road vibration and controlling spring movement. When they wear out, handling deteriorates and metal-on-metal contact accelerates frame and spring damage.
Signs your Ford F-350 Super Duty needs new leaf spring bushings
- Clunking or banging from the rear suspension over bumps, railroad tracks, or uneven pavement
- Squeaking or creaking from under the vehicle when the suspension compresses or rebounds
- Visible cracking, splitting, or collapse of the rubber bushing material on inspection
- Rear axle feels like it is shifting or walking sideways during acceleration or braking
- Uneven or accelerated tire wear on the rear axle caused by misaligned spring geometry
- Loose, vague steering feel or the rear end feels unstable when towing or carrying a load
Which leaf spring bushings should you buy for your Ford F-350 Super Duty?
The main choice is material: rubber bushings restore a quiet, factory-like ride, while polyurethane bushings offer greater durability and precision at the cost of more noise and vibration. Position also matters — eye-end bushings and center-pin bushings are not interchangeable, so confirm which location is worn before ordering.

Replacing leaf spring bushings on a Ford F-350 Super Duty
Moderate⏱ 1.5–3 hoursFloor jack and jack stands rated for the vehicle's weightBushing press or C-clamp with appropriate driver socketsBreaker bar and socket setPenetrating oil (for seized bolts and shackle pins)Torque wrench
Support the frame securely on jack stands and allow the rear axle to hang freely so the spring is unloaded before removing any hardware. Bushing removal typically requires a press or a heavy C-clamp with stepped sockets — driving the old bushing out with a hammer alone risks damaging the spring eye. Always torque the leaf spring bolts and shackle nuts with the suspension at ride height, not while the axle is hanging, so the bushing sets in its neutral position and does not tear prematurely.
Frequently asked questions
How much does it cost to replace leaf spring bushings on a Ford F-350 Super Duty?
Parts alone start at $18.95 for a set of leaf spring bushings for the Ford F-350 Super Duty. A full DIY job typically requires only basic tools and a few hours of time. Shop labor adds cost depending on how seized the hardware is. Delaying replacement risks damage to the spring eyes and frame brackets, which costs significantly more to repair.
How long do leaf spring bushings last on a Ford F-350 Super Duty?
Rubber leaf spring bushings generally last anywhere from 50,000 to over 100,000 miles depending on road conditions, load habits, and climate. Vehicles frequently driven on rough terrain, exposed to road salt, or used for regular towing or hauling will wear bushings significantly faster than those used only for light daily commuting.
Can I drive my Ford F-350 Super Duty with worn leaf spring bushings?
You can drive short distances, but it is not advisable. Worn leaf spring bushings allow the axle to shift position under load and braking, which degrades handling predictability and accelerates tire wear. Metal-to-metal contact between the spring eye and mounting bolt will also damage the spring and bracket, turning a low-cost bushing job into a major repair.
Do I need to replace leaf spring bushings in pairs on a Ford F-350 Super Duty?
Yes, replacing bushings in axle pairs — both sides at the same time — is strongly recommended. Mismatched bushing compliance side-to-side causes uneven spring rates, which can pull the axle out of alignment and create handling imbalance, especially noticeable during braking or when carrying cargo. Matching both sides ensures predictable, symmetrical suspension behavior.
Are polyurethane leaf spring bushings worth it for a Ford F-350 Super Duty?
Polyurethane bushings are worth the upgrade if the Ford F-350 Super Duty is used for towing, hauling, or off-road driving. They outlast rubber significantly and provide tighter axle location under load. For a strictly unloaded daily driver, the firmer ride and occasional squeaking from polyurethane may not be a worthwhile trade-off over quality OE-replacement rubber.
What causes leaf spring bushings to wear out prematurely on a Ford F-350 Super Duty?
The most common causes are frequent off-road or rough-road use, consistent overloading beyond the vehicle's rated capacity, and exposure to road salt or ozone that degrades rubber compounds. Lack of lubrication on greaseable bushing designs, improper installation that twists or pinches the bushing, and using mismatched hardware also shorten bushing service life considerably.
