Control Arm & Toe Arm Kits with Fitting Position Front Axle, Rear Axle for SUBARU FORESTER SH

Control arm and toe arm kits replace or upgrade the arms that locate a wheel on independent suspension, including the toe arm that sets the wheel's toe angle. They are most common at the rear of vehicles with independent rear suspension, where several arms work together to hold each wheel in place. Worn or bent arms let the wheel's angles change as the vehicle moves, which can cause uneven tyre wear and an unsettled feel. Kits are specific to each vehicle, so use the vehicle search to find control arm and toe arm kits to suit your SH FORESTER.

What Is a SH FORESTER Toe Arm?

Toe is the angle of the wheels toward or away from each other when viewed from above. If the fronts of the wheels point slightly inward, that is toe-in. If they point outward, that is toe-out. Manufacturers specify a small amount of toe for each axle, chosen for stability and tyre life.

At the front of most vehicles, toe is set through the steering tie rods. At the rear of a vehicle with independent rear suspension, there is no steering, so a separate arm, called a toe arm or toe link, holds the wheel at the correct toe angle. The toe arm is usually a short link connecting the wheel carrier to the subframe, and on many vehicles its length or mounting position is adjustable so toe can be set during an alignment.

How SH FORESTER Control Arms and Toe Arms Work Together

Independent rear suspension often uses a multi-link design, with several arms holding each wheel. Lower control arms usually carry most of the load and locate the wheel side to side. Upper arms help control camber, and the toe arm controls toe. Together, they let the wheel move up and down while holding it at the correct angles.

Because the arms share the job of locating the wheel, wear in one affects the others. A worn bush in a lower control arm can let the wheel move in a way that changes toe, even if the toe arm itself is sound. That is one reason control arms and toe arms are often replaced together as a kit.

Does Your SH FORESTER Have Toe Arms?

It depends on the vehicle. Many traditional 4WDs and bakkies use a solid rear axle, located by leaf springs or by trailing arms and a panhard rod. On a solid axle, both rear wheels are fixed to the same housing, so rear toe is set by the axle itself and there are no separate toe arms.

Some 4WD wagons and SUVs use independent rear suspension, and those vehicles typically have rear control arms and toe arms. Whether your vehicle uses them depends on its rear suspension design, so check the vehicle's specifications before ordering.

Why Rear Toe Matters on Your SH FORESTER

Rear toe has a strong effect on how a vehicle tracks and how its tyres wear. Incorrect rear toe makes the rear tyres scrub as they roll, wearing the inner or outer edges and sometimes leaving a feathered pattern across the tread. It can also make the vehicle feel unstable, particularly at highway speed or when changing lanes, because the rear wheels are not running straight.

If rear toe differs from one side to the other, the vehicle can crab slightly, with the rear wheels steering it to one side. That can cause the steering wheel to sit off-centre when driving straight, even when the front alignment is correct.

SH FORESTER Rear Toe, Loads and Towing

On independent rear suspension, the rear arms change angle as the suspension compresses, and that can change toe. When a vehicle is heavily loaded or towing, the rear sits lower, and toe may shift from its unladen setting. A small change is expected and is allowed for in the vehicle's design, but worn arms or bushes can exaggerate it, making the vehicle feel less stable when loaded.

If your vehicle regularly carries a heavy load or tows, have the rear alignment checked with the vehicle at its usual ride height, and check the arms and bushes for wear. A vehicle that feels settled when empty but unstable when loaded is a sign the rear suspension is worth inspecting.

SH FORESTER Adjustable Toe Arms

Adjustable toe arms allow the arm's length to be changed, usually with a threaded section and locking nuts. They let toe be set precisely during an alignment, which is useful where the factory adjustment range has been exceeded or where ride height has changed. Once set, the locking nuts hold the adjustment, and they should be checked periodically.

Changing ride height on an independent rear suspension vehicle can alter toe as the arms change angle. Adjustable toe arms give the alignment the range to correct it.

Signs of Worn SH FORESTER Control Arms or Toe Arms

Common signs include uneven rear tyre wear, particularly on the inside or outside edges, a vehicle that feels unstable or wanders at speed, and clunks or knocks from the rear over bumps. The steering wheel may sit off-centre even after a front alignment, which can point to a rear toe problem.

Inspect the arms for bends, especially after an impact with a kerb, rock or pothole, and check the bushes for cracking, splitting or movement in their housings. A bent toe arm changes toe immediately, so any impact to a rear wheel is worth checking.

SH FORESTER Kit or Individual Arms?

A kit suits vehicles with several worn arms, which is common on higher-kilometre vehicles since the arms wear at similar rates. Replacing them together restores consistent geometry and avoids repeated alignments. Individual arms suit a single fault, such as one bent toe arm or one worn control arm, where the rest of the suspension is in good condition.

When replacing a single arm, check its partner on the other side, since uneven wear between left and right can leave the vehicle tracking unevenly.

SH FORESTER Arms and Bushes

Most replacement arms come with new bushes and, where fitted, new ball joints. Replacing the complete arm renews every wear point at once and removes the need to press bushes in and out. Where an arm is straight and only its bushes are worn, replacing the bushes alone can be an option, but a complete arm is often simpler when several bushes need attention.

Fitting SH FORESTER Control Arm and Toe Arm Kits: An Overview

Fitting should be carried out by a qualified technician. The vehicle is supported on rated stands, and each arm is disconnected and replaced in turn. Before removing an adjustable arm, its length is often measured so the new arm can be set close to the previous setting. Pivot bolts through bushes should generally be tightened with the vehicle at normal ride height, and all fasteners tightened to the manufacturer's torque specifications.

A wheel alignment is required after fitting, since control arms and toe arms set the rear wheel angles. The alignment should be done with the vehicle at its normal ride height.

Find the Right SH FORESTER Arm Kit with Formula 4x4

These kits sit within the Formula 4x4 suspension arms range.

Start by confirming that your SH FORESTER has independent rear suspension, and have the arms, bushes and alignment checked to see what needs replacing. Note whether the ride height has changed, which may call for adjustable arms. Search by your SH FORESTER to find control arm and toe arm kits to suit it.
