Leaf Spring Bushes

Whiteline leaf spring bushes restore tight, predictable axle control to leaf sprung vehicles. Each kit replaces worn factory rubber with Whiteline polyurethane, which holds the axle firmly in place, resists wear and stays consistent under heavy loads.

The range covers front eye, rear eye and shackle bushes, complete leaf spring bush kits, saddle insulators and slipper pads. It suits 4WDs and 4x4s, pick-ups and light commercials, vans and classic passenger cars, on front and rear axles.

What Leaf Spring Bushes Do

Leaf spring bushes sit inside the eyes at each end of the spring and in the shackle that links the spring to the chassis. They let the spring pivot and flex as the suspension moves, while stopping metal-on-metal contact and absorbing vibration.

Most importantly, they locate the axle. The bushes control how far the axle can shift forwards, backwards and sideways under acceleration, braking and cornering. When they wear, the axle starts to move on its own, and the vehicle?s handling and stability suffer.

Signs Your Leaf Spring Bushes Need Replacing

Rubber bushes break down over time from load cycles, heat, road grime, water and age. Common signs of worn leaf spring bushes include:

• Clunking or knocking from the suspension over bumps, or when taking off and braking
• Squeaking or creaking as the springs flex
• The vehicle wandering, or the rear end feeling vague, especially with a load or trailer
• Axle tramp or wheel hop under hard acceleration
• Uneven or accelerated tyre wear
• Cracked, perished or split rubber, or visible movement at the spring eye

To check, look closely at each spring eye and shackle with the vehicle safely supported. If the bushes are cracked, misshapen or let the pin move off-centre, it?s time to replace them.

Polyurethane vs Rubber Leaf Spring Bushes

Factory rubber bushes are built mainly for comfort and low cost. Under heavy load they deflect, and as they age they soften and crack, allowing more and more axle movement.

Whiteline polyurethane leaf spring bushes are firmer and keep their shape, so the axle stays where it should be. They also offer high load-bearing capacity, strong abrasion resistance, and resistance to oil, grease, ozone and weathering. That makes them well suited to vehicles that work hard, carry weight or tow regularly.

Whiteline formulates its bushes to keep a smooth ride while delivering that extra control, so you get stability without unnecessary harshness.

Types of Leaf Spring Bush Kits

Complete Leaf Spring Bush Kits

These kits replace every bush on a pair of leaf springs in one go: front eyes, rear eyes and shackles. A complete kit is the best choice when the factory bushes are worn throughout, and it means every pivot wears at the same rate.

Front Eye and Rear Eye Bushes

Spring eye bushes are sold separately or in pairs for applications where only one end needs replacing. The front eye bush does most of the work of locating the axle, so it?s often the first to show wear on loaded or towing vehicles.

Shackle Bushes

Shackle bushes sit at the swinging end of the spring and allow it to change length as it compresses. Worn rear shackle bushes are a common cause of knocking and rattles.

Whiteline shackle bushing kits replace them without needing a full kit. Some are also designed to suit greasable shackles.

Saddle Insulators and Slipper Pads

Some applications use rubber insulators between the spring and the axle saddle, or slipper pads where the spring slides on a mount instead of using a shackle. Whiteline polyurethane versions remove the slop and squeaks that develop as the originals wear.

Greasable Pin and Bush Kits

For vehicles that see dust, mud, water or salt, greasable pin kits let you re-lubricate the bushes through a grease nipple without dismantling the suspension.

Benefits of Upgrading Your Leaf Spring Bushes

Fitting Whiteline leaf spring bushes firms up the mounting points that control the axle. The result is:

• Straighter tracking and less rear-end steer
• More stable braking, particularly when loaded or towing
• Less axle wrap and tramp under power
• Reduced clunks, squeaks and vibration
• More even tyre wear
• Longer life for springs, shackles and pins

These improvements show up on daily drives, highway towing and rough, corrugated roads alike.

Finding the Right Kit for Your Vehicle

Each Whiteline kit is engineered for specific applications. Search by your vehicle, then use the Fitting Position filter to choose front or rear axle.

Read the fitment notes on each listing. Some kits come in more than one size, listed by outside diameter or length.

If your vehicle runs aftermarket springs, the eye size may differ from the original. Use the Bushing Size Search to match bushes by dimension.

Installation Tips

Leaf spring bushes can be fitted by a suspension workshop, or by an experienced home mechanic with the right tools and a safe way to support the vehicle. Follow the instructions supplied with your kit, and keep these points in mind:

• Remove the old bush and any outer sleeve completely, then clean the spring eye before fitting.
• Fit any crush tubes supplied with the kit, so the bolts clamp correctly without over-compressing the bush.
• Lubricate the bush surfaces as directed in the instructions. This prevents squeaks and helps the bush pivot smoothly.
• Tighten all fasteners to the manufacturer?s specification.
• Re-check them after the first 500 km (around 300 miles).

Maintenance and Bush Life

Whiteline polyurethane bushes need very little upkeep. Inspect them during routine servicing, checking for squeaks, movement or damage.

On vehicles regularly driven through water, mud or sand, check them more often. If your kit uses greasable pins, grease them at each service.

Well-fitted polyurethane bushes keep their shape far longer than rubber, which protects your springs, shackles and pins for the long term. Every kit is backed by the Whiteline warranty.
