Parts for your 2009 Subaru Outback-Suspension bushes

2009 Subaru Outback suspension bushes — what they do and when to replace them

Suspension bushes are absolutely fitted to the 2009 Subaru Outback. This is confirmed by the Subaru Legacy/Outback 2005–2009 Service Manual (Suspension section) and Subaru’s BP/BL Outback MY2009 parts catalogue, which list control arm (transverse link) bushes, stabiliser (sway bar) mounting bushes, rear lateral/trailing arm bushes, and rear subframe/crossmember bushes. Aftermarket technical catalogues for the BP Outback also offer direct-replacement bushes across these locations, reinforcing their use on this model.

On this Outback, bushes are the rubber (or polyurethane) inserts that sit between suspension arms, brackets and the body. They isolate vibration, quieten road noise, and keep alignment steady under braking, cornering and on rough Kiwi and Aussie backroads. They let the arms move through their arc without metal-on-metal contact, and they’re a key part of ride comfort and tyre life.

• Front lower control arm bushes: control compliance and braking stability.
• Front and rear stabiliser bar bushes: reduce body roll and clunks over bumps.
• Rear lateral and trailing arm bushes: keep the back end tracking straight and stable.
• Rear subframe/crossmember bushes: isolate drivetrain/suspension vibration from the cabin.

Because they’re wear items, regular checks are smart. During routine servicing or every 20,000–30,000 kilometres, look for perishing, cracking, torn voids, oil soak, and excessive movement with a lever. Tell-tales include thuds over speed humps, steering wander, shimmy under braking, rear-end steer, and uneven tyre wear.

When replacement time comes, choosing the right bush makes a difference. OEM-style rubber keeps factory comfort and NVH. Quality polyurethane tightens response and lasts well, but may transmit a touch more road feel. Many owners replace front lower control arm bushes as a pair, or opt for complete arms if the ball joint or arm is tired too. Press-fit bushes need proper tools and orientation marks lined up correctly. Always torque arm bolts at normal ride height to avoid pre-loading the bush, and book a wheel alignment straight after—geometry will shift as fresh bushes remove slop.

Coastal Aussie and NZ conditions can speed up ageing, so a keen eye under the car pays off. Fresh bushes restore that planted Subaru feel, protect tyres, and keep the Outback safe and comfy on long hauls and gravel detours alike.

FAQs

What are the common signs the 2009 Outback’s suspension bushes need replacing?
Clunks over bumps, vague steering, shimmy under braking, or uneven tyre wear are the big giveaways. Visual checks often show cracked, split or oil-soaked rubber, or you’ll see the arm move too easily on a pry-bar.

Can the bushes be replaced without changing the whole control arm?
Yes. Most bushes are serviceable as individual parts if you have the right press tools and follow the service manual. If the arm or ball joint is also worn, a complete arm can be the quicker, cost-effective route.

Do I need a wheel alignment after replacing suspension bushes?
Absolutely. Fresh bushes change the arm positions and reset compliance, so a post-repair alignment is essential for proper handling and to protect your tyres.
