Alignment Arms with Fitting Position Front Axle for MAZDA 2 DE

Alignment arms are suspension arms designed to establish, correct or provide adjustment to your DE 2's wheel alignment geometry. Depending on their design and position within the suspension system, an alignment arm may influence camber, caster or toe.

Some alignment arms provide an adjustable connection that allows technicians to fine-tune a particular wheel angle during alignment. Others use a fixed geometry or offset to provide a predetermined correction for a specific application.

This makes alignment arms different from simply replacing a standard suspension arm with another component of the same geometry. Their purpose can include providing additional alignment capability or changing geometry where the existing suspension arrangement does not provide the required setting.

The function varies considerably between applications. An arm designed to alter toe does not necessarily adjust camber or caster, while another arm may be specifically designed around one of those angles. Always check the individual product specifications to understand what adjustment or correction an arm provides.

How Alignment Arms Change Suspension Geometry for Your DE 2

Wheel alignment describes several geometric relationships between the wheels, tyres, suspension and road. Three of the most important measurements are camber, caster and toe.

An alignment arm can alter one or more mounting positions within the suspension geometry, depending on its design. This changes the position or operating relationship of the connected suspension components and allows the relevant wheel angle to be corrected or adjusted.

Camber

Camber describes the inward or outward inclination of a wheel when viewed from the front or rear of the vehicle.

Changing ride height or other suspension geometry can alter camber. In some suspension designs, an adjustable camber arm provides a means of repositioning the relevant suspension mounting point so the camber angle can be set appropriately.

Camber requirements vary according to the vehicle, suspension configuration and intended use. More negative or positive camber is not automatically better; the appropriate setting needs to be considered as part of the complete wheel alignment.

Caster

Caster relates to the angle of the steering axis when viewed from the side of the vehicle. It influences characteristics such as steering behaviour and straight-line stability.

Where the suspension design permits it, caster correction can be achieved by changing the position of a suspension arm or mounting point. Depending on the application, this may be accomplished with an adjustable arm or an arm manufactured with a predetermined offset.

Not every vehicle uses a dedicated caster arm, and not every alignment arm provides caster adjustment.

Toe

Toe describes the direction the wheels point relative to one another when viewed from above.

A toe arm provides a means of changing this relationship on suspension designs where the arm influences wheel toe. Adjustable toe arms can be particularly useful where the available factory adjustment cannot achieve the required setting.

Correct toe is important because relatively small changes can affect steering behaviour and tyre wear. Toe adjustment should therefore be measured accurately during a wheel alignment rather than estimated visually.

Adjustable vs Fixed-Correction Alignment Arms

Although the terms are often used together, an alignment arm does not necessarily have to be adjustable.

Adjustable alignment arms incorporate a mechanism that changes the effective geometry or position of the arm. This allows an alignment technician to make adjustments within the range provided by that particular component.

Depending on the design, adjustment may be achieved through mechanisms such as threaded sections or other purpose-designed adjustment points.

A fixed-correction arm, by comparison, uses predetermined geometry to produce a particular change without an adjustable range. Fixed-offset designs can be appropriate where a known correction is required for a specific suspension application.

Neither approach is inherently better. The correct choice depends on the suspension design, the alignment correction required and the specifications of the individual product.

Adjustment ranges and mechanisms also differ between products, so they should always be checked in the product specifications rather than assumed from the category.

When Are Alignment Arms Used on the DE 2?

Alignment arms can be useful when the required wheel-alignment geometry cannot be achieved using the adjustment already available in the suspension.

This can occur after changes to suspension geometry, but modification is not the only reason an alignment arm may be required.

Typical situations can include:

• additional camber, caster or toe adjustment is required;
• altered ride height has changed suspension geometry;
• the available factory alignment range is insufficient for the required setting;
• a fixed geometry correction is required for a particular suspension configuration; or
• an existing arm needs replacement and the applicable replacement incorporates alignment correction or adjustment.

An alignment arm should not be selected simply because a vehicle has an alignment problem. Incorrect wheel alignment can have many causes, including worn bushes, damaged suspension components, incorrect ride height or other mechanical issues.

The underlying cause should be identified before choosing the correction method.

Alignment Arms vs Other Alignment Parts

Alignment arms are only one method of changing wheel alignment. Fulcrum's broader range of alignment parts also includes components such as camber bolts, alignment shims and caster correction hardware. These products can provide alternative ways of altering geometry without replacing a complete suspension arm.

The appropriate method depends on the suspension design and the type and amount of correction required.

A camber bolt, for example, changes geometry at a suitable bolted mounting location. A shim alters component positioning by introducing a precisely sized spacer at the relevant mounting point. An alignment arm instead changes geometry through the arm or its mounting relationship.

These products should not automatically be treated as interchangeable. The correct solution is determined by the vehicle's suspension design and the alignment result that needs to be achieved.

Choosing the Right Alignment Arm for Your DE 2

Before selecting an alignment arm, establish which wheel angle needs to be corrected and why.

Important factors to check include:

• Alignment function: Determine whether the arm affects camber, caster, toe or another aspect of suspension geometry.
• Adjustment type: Check whether the product provides adjustable geometry or a fixed correction.
• Adjustment range: Where an arm is adjustable, confirm that its available range is suitable for the required setup.
• Fitting position: Alignment arms are designed for specific locations within the front or rear suspension.
• Suspension configuration: Confirm compatibility with the relevant suspension arrangement and other installed components.
• Included components: Bushes, mounting hardware and other supplied parts vary between products.

Material, construction, adjustment mechanism and included hardware can also vary across the category. Check the individual product specifications rather than assuming every alignment arm shares the same features.

Installation and Wheel Alignment

An alignment arm directly affects suspension geometry, so fitting the component is only part of the job.

After installation, a professional wheel alignment should be performed so the relevant angles can be measured accurately and the arm adjusted where applicable. Adjustable components should be set within their specified operating range and all mounting hardware tightened correctly.

The technician should also consider the alignment as a complete system. Changing one angle can interact with other measurements depending on the suspension design, so individual settings should not be adjusted in isolation without checking the overall result.

Where an alignment issue is related to worn or damaged suspension components, those problems should also be addressed before the final alignment is completed. Additional adjustment cannot compensate for every mechanical fault.
