Parts for your 2005 Subaru Outback-Suspension bushes

2005 Subaru Outback suspension bushes — what they do and when to replace them

Suspension bushes absolutely are fitted to the 2005 Subaru Outback (BP/BL). The Subaru Factory Service Manual for the 2005 Legacy/Outback platform (Front and Rear Suspension sections) and the Subaru electronic parts catalogue both specify multiple rubber bushes throughout the chassis: front lower control arm bushes, stabiliser (sway) bar D-bushes and links, rear lateral link and trailing arm bushes, plus subframe/crossmember mounts. So yes—this Outback relies on bushes to keep things quiet, stable, and aligned.

On this model, bushes isolate vibration and road harshness while keeping suspension arms located so wheel alignment stays true under braking, cornering, and load. Many variants use a large, fluid-filled (hydraulic) front lower control arm rear bush to tame shimmy and brake shudder. When these wear, the car can wander, clunk over bumps, tramline, or show uneven tyre wear and feathering.

• Front: lower control arm front and rear bushes, stabiliser bar D-bushes and link bushes
• Rear: lateral link and trailing arm bushes, stabiliser bar D-bushes and link bushes, rear subframe mounts

As part of routine servicing in Australia and New Zealand, it’s smart to inspect bushes yearly or every 20,000 km—especially if the Outback tows, tackles corrugations, or lives near the coast. Look for cracked rubber, separation from the sleeve, excessive arm movement under a pry bar, and on hydraulic bushes, any tell-tale fluid weep.

When replacement’s due, doing both sides of an axle keeps handling balanced. Press-fit bushes need proper tools and orientation marks lined up as per the FSM. Always torque pivot bolts at normal ride height to avoid preloading the rubber. Any time control arms or rear links come out, plan on a four-wheel alignment. Sway bar D-bushes alone generally won’t affect alignment.

Choosing parts? Genuine-style rubber keeps factory comfort and noise levels. Quality polyurethane can sharpen response and last longer, but it can add a bit of NVH and may need periodic greasing to prevent squeaks. In rust-prone regions, expect some seized bolts—have new hardware on hand where Subaru specifies replacement. After installation, a short recheck once the bushes have settled is a good move, especially if the vehicle carries loads or hits gravel regularly.

Popular questions about 2005 Subaru Outback suspension bushes

How long do the bushes typically last?
Many Outbacks see 80,000–150,000 km from factory bushes, but life varies with roads, climate, tyres, and towing. Coastal exposure and rough tracks can shorten that. If there’s clunking, steering kickback, or uneven tyre wear, don’t wait for a set kilometre number—inspect and replace as needed.

Will polyurethane bushes make it too harsh?
Polyurethane tightens steering feel and can last longer, but there’s usually a small trade-off in vibration and road feel transmitted into the cabin. On this Outback, using poly in selected spots (e.g., sway bar D-bushes) and keeping critical control arm bushes rubber is a popular compromise.

Do I need an alignment after bush replacement?
If any control arms or rear links are removed or their bushes are changed, yes—book a four-wheel alignment. Replacing only sway bar D-bushes or drop links typically doesn’t change alignment, but it’s still wise to check tyre wear and steering feel afterwards.
