Parts for your 2009 Subaru Tribeca-Control arms

2009 Subaru Tribeca Control Arms

Control arms are absolutely used on the 2009 Subaru Tribeca. Technical references include the Subaru Factory Service Manual for 2008–2009 Tribeca (Front Suspension and Rear Suspension sections), which specifies a front lower control arm linked to the steering knuckle via a ball joint, and a multi-link rear arrangement with lateral links (commonly referred to as rear control arms). Subaru’s FAST parts catalogue and major aftermarket catalogues (e.g., MOOG and Mevotech) also list complete front lower control arm assemblies and rear lateral link/control arm components for this model. So, control arms are relevant, fitted, and serviceable on this vehicle.

On the Tribeca, the front lower control arms are the pivoting links that locate the front hubs, controlling wheel alignment as the suspension moves. They use inner rubber bushes to absorb vibration and a ball joint at the outer end to allow steering and vertical movement. The rear multi-link setup uses several arms to keep the wheel tracking straight and maintain camber and toe under load. Healthy arms and bushes are key for stable handling, even tyre wear, and a quiet ride.

As part of regular servicing, it’s smart to inspect the control arm bushes and ball joints every 20,000–30,000 km or at each WOF/service. Look for perished or torn bushes, leaking ball joints, loose hardware, and uneven tyre wear. A Tribeca with tired control arm bushes may feel vague on the motorway, clunk over bumps, or shimmy under braking.

When replacement is due, many owners opt for complete arm assemblies to get fresh bushes and ball joint in one go, especially on the front where alloy arms are common. Always torque the arm bolts with the vehicle at normal ride height to avoid preloading the bushes, and follow with a professional wheel alignment. Replacing in axle pairs (both fronts or both rears of the same type) helps maintain even handling.

• Common signs: clunks on take-off/braking, wandering steering, steering wheel shimmy, inner or outer tyre wear, and a “floaty” feel over bumps.
• Service tips: use new self-locking nuts where specified, check ball joint boots, and inspect sway bar links at the same time.
• After any control arm work: book a full alignment to reset camber/caster/toe and protect those tyres.

FAQs

Does the 2009 Tribeca have both front and rear control arms?
Yes. The front uses lower control arms with a ball joint to the knuckle, while the rear features a multi-link layout with lateral links and trailing arms that serve as the rear control arms. This arrangement keeps alignment consistent and ride quality smooth.

How long do control arm bushes typically last on a Tribeca?
It varies with road conditions and driving style, but many see 100,000–160,000 km before noticeable wear. Regular checks during services help pick up early cracking or play, which can save tyres and improve safety.

Do I need a wheel alignment after replacing control arms?
Definitely. Any change to arms, bushes, or ball joints can shift alignment. A proper alignment after installation ensures the Tribeca steers straight, handles predictably, and avoids premature tyre wear.
