Axle Bushes with Fitting Position Front Axle, Rear Axle for HYUNDAI PONY X2 (Bonnet opens from front grill)

Axle bushes are the rubber or polyurethane pivots that connect a solid axle to the chassis. Every link that locates a 4WD's axle, whether it is a radius arm, a trailing arm, a panhard rod or a leaf spring, mounts through bushes at each end. They let the axle move up, down and through its articulation while stopping it from moving anywhere else. When they wear, the axle starts to shift under braking, acceleration and cornering, and the vehicle feels it before the owner can see it. Use the vehicle search to find axle bushes to suit your X2 (Bonnet opens from front grill) PONY.

What Do X2 (Bonnet opens from front grill) PONY Axle Bushes Do?

A solid axle has to move freely in one direction and stay firmly located in every other. The links around it handle the location. The bushes are what let those links pivot.

Each bush is a sleeve of rubber or polyurethane pressed into the eye of a link, with a steel inner sleeve that the mounting bolt passes through. As the axle rises and falls, the link swings and the bush flexes. As the axle tries to move forwards under braking or sideways in a corner, the bush resists.

The bushes also take the shock and vibration that would otherwise travel straight from the axle into the chassis. A good bush is doing two jobs at once: allowing controlled movement and refusing uncontrolled movement.

Where X2 (Bonnet opens from front grill) PONY Axle Bushes Are Found

On a coil sprung solid axle, the main bushes sit at each end of the radius arms or trailing arms, at the upper links where fitted, and at both ends of the panhard rod. On a leaf sprung axle, the bushes sit in the spring eyes at the front hanger and in the shackle at the rear, and the leaf spring locates the axle as well as carrying it.

A Note on the Term

On some small passenger cars, "axle bushes" refers to the pivot bushes on a twist-beam rear axle. That is a different design from a 4WD solid axle. If you are unsure which part your vehicle uses, check the product details or ask before ordering.

Why Axle Bushes Matter More on Your X2 (Bonnet opens from front grill) PONY

A solid axle is heavy, and it carries the diff, the wheels, the brakes and on a front axle, much of the steering. Every time that mass moves, the bushes take the load.

Off road, the axle articulates far beyond what it sees on the highway. Links swing through big arcs and twist against each other, and the bushes are pushed well past their resting position. Corrugations add thousands of small cycles in a short distance. Heavy loads and towing add force to every one of those cycles.

That is why bushes on a working 4WD generally wear faster than on a vehicle that stays on bitumen, and why worn bushes on a 4WD are felt more clearly.

What Types of X2 (Bonnet opens from front grill) PONY Axle Bushes Are There?

Rubber Bushes

Rubber is the material most vehicles leave the factory with. It is generally quiet, absorbs vibration well and gives a softer ride. It also deflects more under load, and over time it can crack, perish and soften, especially when exposed to oil, heat and sunlight.

Polyurethane Bushes

Polyurethane is generally firmer than rubber and holds its shape under load. It can resist oil and chemicals better and tends to keep the axle more precisely located, which many owners notice as sharper steering and less movement under braking. It may transmit a little more noise and vibration, and some designs need lubrication to stay quiet.

Offset and Caster Bushes

Some axle bushes are made with an offset inner sleeve. Fitted at the radius arm, these rotate the axle slightly to change caster after a lift. They are generally suited to modest lifts, and the correction they offer is limited.

X2 (Bonnet opens from front grill) PONY Spring Eye and Shackle Bushes

On a leaf sprung axle, the spring eye and shackle bushes carry the spring's location as well as its pivot. They work under constant load and see the full length of the spring's movement, so they are often among the first bushes to show wear on a working ute.

How Do You Know X2 (Bonnet opens from front grill) PONY Axle Bushes Are Worn?

The axle tells you through the steering and the seat. A clunk when taking off, braking or crossing dips often points to bushes letting the axle move fore and aft. A vehicle that wanders, needs constant correction on the highway, or feels as though the rear is steering on uneven roads can have worn link or panhard bushes.

Front axle bushes also affect the steering directly. Worn radius arm bushes can let caster change under braking and can contribute to shimmy or wobble after a bump. Worn panhard bushes can let the axle shift sideways, which is felt as a delay between turning the wheel and the vehicle responding.

Inspection usually confirms it. Bushes that are cracked, split, squashed out of shape or walking out of their housings need replacing. So do bushes where the inner sleeve has moved off centre without being designed to.

Steering components, wheel bearings and shocks can produce similar symptoms, so a full inspection is worth doing before ordering.

X2 (Bonnet opens from front grill) PONY Lifted, Loaded and Towing Considerations

Lifted X2 (Bonnet opens from front grill) PONY

A lift changes the resting angle of every link. If the bushes were tightened with the axle hanging and the vehicle then set down at a new height, they sit permanently twisted. A twisted bush wears faster and can tear. Lifted vehicles generally benefit from having all axle bush bolts released and retightened at the new ride height.

A lift also changes caster on a coil sprung front axle. Offset bushes can recover some of it, but larger lifts usually need a more complete correction.

Loaded and Touring X2 (Bonnet opens from front grill) PONY

Bull bars, winches, drawers and touring gear increase the force through every axle bush, particularly under braking and over corrugations. A loaded vehicle's bushes are worth checking at each service and before a long trip.

Towing With Your X2 (Bonnet opens from front grill) PONY

Towing puts large fore and aft forces through the axle locating links. Worn bushes let the axle shift under those forces, which can show up as a clunk on take-off or a less settled feel with a trailer behind.

What Comes With X2 (Bonnet opens from front grill) PONY Axle Bushes?

Bush kits vary widely. Some cover one link, others cover a full axle. Inner sleeves, washers and lubricant may or may not be included, and mounting bolts are often supplied separately. Check the product details for what is included and how many bushes are in the kit.

Should You Replace the X2 (Bonnet opens from front grill) PONY Bushes or the Link?

New bushes are usually enough when the link is straight, free of cracks and the bush housing is still round. Replacing just the bushes restores location at a lower cost than a complete link.

Replacing the link makes more sense when it is bent or cracked, when corrosion has thinned the metal, or when the bush housing has worn oval and a new bush will not hold. On leaf sprung vehicles, a sagged or cracked spring is a reason to replace the spring, and new bushes are generally fitted with it.

Fitting X2 (Bonnet opens from front grill) PONY Axle Bushes

Replacing axle bushes usually means removing links and pressing bushes in and out, so it is a job for a qualified technician. The vehicle goes on rated stands, and the axle is supported so it cannot move when a link is removed. Old bushes are pressed out, the housings are cleaned and checked, and the new bushes are fitted with any lubricant or sleeves supplied.

Bush bolts are tightened at ride height, with the vehicle's weight on the suspension, so the bushes start in their neutral position. All fasteners are torqued to specification. A wheel alignment is required after front axle bushes are replaced, and a road test confirms the result.

Find the Right X2 (Bonnet opens from front grill) PONY Axle Bushes with Formula 4x4

Use the vehicle search, then confirm which links need attention and whether the vehicle has a coil or leaf sprung axle. Check the product details for what is included. Book a wheel alignment after fitting.

Axle bushes are part of our suspension bushes range, along with panhard rod bushes for the other big pivot on a live axle.
