Parts for your 2011 Subaru Legacy-Sway bars & links

2011 Subaru Legacy sway-bars-&-links

Relevant technical sources confirm the 2011 Subaru Legacy (BM/BR) is factory-fitted with front and rear stabiliser bars (sway bars) and corresponding link assemblies, so sway-bars-&-links are absolutely used on this model. The Subaru Service Manual for 2010–2012 Legacy/Outback (Front Suspension > Stabilizer System, Rear Suspension > Stabilizer System) specifies a stabiliser bar, D-bushes and stabiliser link assemblies at both ends. The official Subaru parts catalogue for the 2011 Legacy also lists front and rear stabiliser bars, D-bushes, brackets and link assemblies, while common aftermarket catalogues list direct-fit links and bushes for this vehicle. That means sway-bars-&-links are relevant to ride and handling on every 2011 Subaru Legacy variant.

On the 2011 Subaru Legacy, the sway bar is a cross-car torsion spring that ties the left and right suspension together to reduce body roll in corners. The end links connect the bar to the control arm or strut, transferring load as the car leans. The result is flatter cornering, more predictable steering and steadier tyre contact over bumpy Kiwi and Aussie roads.

For servicing, it’s smart to inspect the sway-bars-&-links at every routine service or at least every 20,000 km. Look for perished D-bushes, torn link boots, play in the ball studs and any clunks when driving over speed bumps or turning into driveways. A light film of road grime is normal, oil-soaked bushes or split dust boots are not. If a link is loose or a bush is ovalled out, replace the affected parts as a set on that axle for balanced behaviour.

Replacement is straightforward for a competent tech: support the suspension at ride height, remove the old links and D-bush brackets, seat new bushes with the flats aligned to the bar, and torque all fasteners to Subaru specifications. Penetrating fluid helps with stubborn, corroded link studs. An alignment isn’t normally required because the bar and links don’t change camber/toe, but if other suspension work is done at the same time, a check never hurts.

Owners can choose OEM-style rubber bushes for factory feel and low NVH, or quality polyurethane bushes for a firmer, more immediate response. If upgrading bar diameter (where suitable for the trim), expect reduced roll and a touch more steering bite, pair this with good tyres to make the most of it. Keep things quiet by lubricating poly bushes with the correct grease and rechecking link nut torque after a few hundred kilometres.

• Typical symptoms of wear: hollow knock over bumps, metallic clunk at low speed, vague turn-in, or uneven tyre edge scuffing.
• Practical tip: replace links and D-bushes together if they’re the same age, it’s inexpensive insurance against repeat visits.

Popular questions about 2011 Subaru Legacy sway-bars-&-links

How long do sway bar links and bushes usually last on a 2011 Legacy?
Service life varies with roads and climate, but many see 80,000–150,000 km before the links or D-bushes get noisy or loose. Frequent gravel or corrugations can shorten that, so listen for knocks and have them checked at regular services.

Do I need a wheel alignment after replacing sway bar links or D-bushes?
No. Changing sway bar links or bushes doesn’t alter alignment angles. If you’ve also changed control arms, struts or anything that shifts geometry, book an alignment, otherwise you’re fine.

Are polyurethane bushes worth it on a daily-driven Legacy?
They can sharpen response and reduce roll a touch, but may transmit a bit more road feel. For a daily in Aussie or NZ conditions, quality OEM rubber is quiet and comfy, choose poly if you prefer a sportier feel and don’t mind a tad more feedback.
