Idler Arms with Fitting Position Front and Rear, Front Axle for FORD FALCON XA, XB

Nolathane idler arms are complete, direct-fit replacements for worn or damaged XA, XB FALCON steering idler arms. When an idler arm has worn beyond the point where new bushes alone will fix it, a complete replacement restores firm support to the centre link, correct steering geometry and the tight, predictable steering feel your XA, XB FALCON was designed to deliver.

Built from high-strength materials for long service life, Nolathane idler arms suit classic and older passenger vehicles, as well as other applications with parallelogram steering linkages, especially where quality replacement parts can be hard to find.

The Role of the Idler Arm

In a parallelogram steering system, the steering box turns a pitman arm, which moves a centre link from side to side. The centre link carries the tie rods that steer each front wheel.

The idler arm is mounted on the opposite side of the vehicle from the pitman arm, bolted to the chassis or subframe. It pivots freely to support its end of the centre link, mirroring the pitman arm?s movement and holding the centre link at the correct height. Without a healthy idler arm, the centre link can?t stay level, and steering accuracy suffers on both sides of the vehicle.

How an Idler Arm Is Built

A typical idler arm assembly has three main elements:

• A mounting bracket that bolts to the chassis or subframe
• A pivot, usually through a bush or bearing, that allows the arm to swing as the steering turns
• An arm with a tapered socket or joint at the outer end, which connects to the centre link

Wear can occur at the pivot, at the outer joint, or in the arm itself if it has been bent or corroded. Knowing where the wear is helps you decide between a bush replacement and a complete idler arm.

When a Complete XA, XB FALCON Idler Arm Is Needed

Replacing only the bush is a good repair when the arm and its outer joint are in good condition. A complete idler arm is the better choice when:

• The outer joint or socket has worn and developed play
• The arm is bent from an impact with a kerb, pothole or debris
• The mounting bracket or pivot housing is worn, cracked or corroded
• The pivot has worn so far that a new bush can?t restore firm support
• You?re restoring a vehicle and want every steering component returned to new condition

In these situations, fitting a complete replacement idler arm restores the linkage fully, rather than leaving a worn part in service.

Warning Signs of a Bad Idler Arm on the XA, XB FALCON

• Steering that feels loose, with play before the wheels respond
• The vehicle drifting, wandering or pulling to one side on a straight road
• Clunking or knocking from the front end when turning or driving over bumps
• Uneven tyre wear, often on the inner or outer edges of the front tyres
• A steering wheel that sits off-centre when driving straight
• Visible up-and-down movement at the idler arm when the steering is rocked

It isn?t advisable to keep driving with a bad idler arm. If it fails completely, steering control can be seriously affected.

What Causes Idler Arms to Fail

Idler arms are durable, and with good care many last for years. However, several factors speed up wear:

• High kilometres: constant pivoting gradually wears the pivot and outer joint
• Road conditions: potholes, rough roads and impacts load the steering linkage
• Heavy use: towing, loads and frequent sharp turns increase stress
• Corrosion: moisture and road grime attack metal parts and seals
• Lack of lubrication: greasable designs wear faster when servicing is missed
• Accident or kerb damage: an impact can bend the arm or damage the joint
• Loose fasteners: an idler arm left loose after earlier work wears quickly

Why Replace a Worn Idler Arm Promptly

A worn idler arm doesn?t just affect how the vehicle feels to drive. Play in the linkage changes toe settings as you steer and travel over bumps, making the vehicle less stable, especially at highway speeds, in wet conditions or during emergency manoeuvres. It also accelerates wear on the pitman arm, centre link, tie rod ends and tyres.

On some vehicles, it makes sense to inspect, and if needed replace, the idler arm and pitman arm together, so both sides of the linkage are in matching condition.

Idler Arms for Classic and Older Vehicles

Many classic cars and older passenger vehicles use parallelogram steering, and finding quality replacement idler arms for them can be difficult. Nolathane idler arms are designed as direct-fit replacements for applicable vehicles. They restore correct steering function and give restorers a reliable, long-lasting solution. Fitting a new idler arm as part of a full steering restoration, alongside new bushes and other steering components, brings back the precise steering feel these vehicles are known for.

What Affects Idler Arm Replacement Cost

The cost of replacing an idler arm depends on the vehicle, how easily the arm can be reached, whether other steering components also need replacing, and the wheel alignment that follows. Replacing a worn idler arm early helps avoid the extra cost of replacing tyres and other steering parts that wear faster when the linkage is loose.

Replacing an Idler Arm on Your XA, XB FALCON

Idler arm replacement suits professional workshops and experienced home mechanics with a sound understanding of steering systems. As a general guide:

• Raise the vehicle safely, support it on stands, and remove the front wheel for access if needed.
• Set the steering straight ahead.
• Remove the split pin and castle nut from the outer joint, then separate the idler arm from the centre link with a suitable tool.
• Unbolt the idler arm bracket from the chassis or subframe and remove the old arm.
• Fit the new idler arm in the same position and orientation as the original.
• Connect the outer joint to the centre link, tighten the castle nut to the specified torque, and fit a new split pin.
• Tighten the mounting bolts to specification, and grease the arm if it has a grease fitting.

Have a wheel alignment carried out after replacing the idler arm, then test drive the vehicle to confirm the steering is tight, centred and free of noise.

Looking After Your Idler Arm

To get the longest life from your new idler arm, inspect it at every service, check the mounting bolts remain tight, and lubricate it at the intervals recommended by the vehicle manufacturer if it has a grease fitting. Keep an eye on front tyre wear, as uneven wear is often the first sign that steering components need attention.
