WHITELINE, MCA, RIVAL, FOX Toe Arm Bushes

Toe arm bushes are the pivot points at each end of a toe arm, the suspension link that controls the toe angle of the rear wheels. When these bushes wear, the rear wheels can shift and steer slightly on their own under braking, cornering and acceleration. This affects stability, alignment and tyre life.

This range of rear toe arm bushes includes inner, outer, and combined inner and outer toe arm bush kits, with polyurethane options designed for longer life and more precise rear toe control.

What Is a Toe Arm?

A toe arm is a suspension link found in many independent rear suspension systems. It's also known as a toe link or toe control arm. It connects the chassis or subframe to the rear hub or knuckle, and its main job is to control the rear wheel's toe angle as the suspension moves.

Without a toe arm, forces from braking, cornering and bumps could cause the rear wheel to turn slightly in or out, effectively steering the rear of the vehicle. The toe arm holds the wheel pointing in the right direction, keeping the rear end stable and predictable.

On many vehicles, the rear toe arms are also where rear toe is adjusted during a wheel alignment.

What Toe Arm Bushes Do

Each toe arm has a bush at each end:

• The inner bush connects the toe arm to the chassis or subframe.
• The outer bush connects the toe arm to the rear hub or knuckle.

Together, these bushes:

• Allow the toe arm to pivot as the suspension moves up and down
• Control unwanted movement, so the rear wheel holds its toe angle under load
• Absorb vibration and noise between metal components
• Help maintain rear toe alignment, so the vehicle tracks straight and tyres wear evenly

How Worn Toe Arm Bushes Affect Rear Toe Alignment

Toe alignment describes whether the wheels point slightly inwards or outwards when viewed from above. Even small changes in rear toe can make a noticeable difference to how a vehicle drives and how its tyres wear.

Toe In vs Toe Out

• Toe in means the front of the wheels point slightly towards each other. At the rear, a small amount of toe in generally helps stability, particularly when cornering.
• Toe out means the front of the wheels point slightly away from each other. Rear toe out can make the rear of the vehicle feel nervous or unsettled.

Each vehicle has a manufacturer specification for rear toe. A wheel alignment sets the toe to that specification.

What Happens When Toe Arm Bushes Wear

When toe arm bushes become worn, cracked or soft, the toe arm can move more than it should. The rear toe angle then changes as the vehicle brakes, accelerates, corners or hits bumps, even if the static alignment is correct. This can lead to:

• A rear end that feels loose or shifts during cornering and lane changes
• Reduced stability under braking
• Uneven rear tyre wear
• An alignment that's difficult to set accurately or doesn't hold

Replacing worn toe arm bushes restores control of the rear toe, helping the vehicle hold its alignment on the road, not just on the alignment machine.

Signs Your Toe Arm Bushes May Be Worn

Look out for these common warning signs:

• Uneven rear tyre wear, especially on the inner or outer edges, or a feathered feel across the tread
• Vague or unstable rear-end feel, particularly when cornering, changing lanes or braking
• Clunking or knocking from the rear suspension over bumps
• The vehicle wandering or needing constant steering correction
• Visible damage, such as cracked, split, perished or oil-soaked rubber
• Excess movement in the toe arm at its mounting points

If you notice any of these, have the rear suspension inspected. A free suspension check can confirm whether the toe arm bushes, or another suspension component, is causing the problem.

Types of Toe Arm Bush Kits

Toe arm bushes are sold as kits for specific positions, so you can replace exactly what's needed.

Inner Toe Arm Bush Kits

An inner toe arm bush kit replaces the bushes where the toe arm mounts to the chassis or subframe. It's a good choice if only the inner bushes are worn or if you want to firm up the chassis end of the toe arm.

Outer Toe Arm Bush Kits

An outer toe arm bush kit replaces the bushes where the toe arm connects to the rear hub or knuckle. These bushes see constant movement as the wheel travels and can wear independently of the inner bushes.

Inner and Outer Toe Arm Bush Kits

An inner and outer toe arm bush kit, sometimes called a toe control arm inner and outer bush kit, replaces the bushes at both ends of the toe arm. Replacing both at once restores full control of rear toe and saves doing the job twice.

Polyurethane or Rubber Toe Arm Bushes?

Rubber Toe Arm Bushes

Rubber is commonly used in factory bushes. It's soft and absorbs noise and vibration well, but it can deflect under load and deteriorate over time with age, heat and exposure to oil.

Polyurethane Toe Arm Bushes

Polyurethane is a popular upgrade material. It's generally firmer and more resistant to wear, oils and temperature extremes than rubber. Polyurethane toe arm bushes can:

• Reduce deflection, so rear toe stays more consistent under load
• Help improve rear-end stability and handling precision
• Last longer, particularly for vehicles that are driven hard, towed with or heavily loaded

Because polyurethane is firmer, some drivers may notice a little more road feel. For most drivers wanting precise, consistent rear toe control, polyurethane is a worthwhile upgrade.

Choosing the Right Toe Arm Bush Kit

Before you buy, check:

• Vehicle fitment. Confirm the kit suits your vehicle's make, model, year and series.
• Position. Decide whether you need inner, outer, or inner and outer toe arm bushes.
• Kit contents. Check how many bushes and sleeves are included and whether one kit covers both sides of the vehicle.
• Material. Choose between rubber for comfort or polyurethane for durability and control.
• The condition of the rest of the rear suspension. If other rear bushes are also worn, replacing them together helps restore consistent handling. Browse the full range of suspension bushes to find matching parts.

Fitting Toe Arm Bushes and Wheel Alignment

Replacing toe arm bushes usually involves removing the toe arm, pressing out the old bushes and pressing in the new ones. This can require a press and specialist tools, so many people choose professional fitting.

Because the toe arm directly controls rear toe, a wheel alignment is needed after fitting new toe arm bushes. The alignment sets rear toe back to specification and helps prevent uneven tyre wear.

When fitting, follow the manufacturer's instructions for lubrication and tightening, and tighten all fasteners to the specified torque.

Find Toe Arm Bushes for Your Vehicle

Use the vehicle search to filter toe arm bushes by make, model, year and series. Each product page lists compatible vehicles, the bush position, kit contents and fitted pricing.

If the rear alignment still won't come into spec, alignment bushes add adjustment, and trailing arm bushes are worth checking at the same time.
