Parts for your 2015 Subaru Legacy-Sway bars & links

2015 Subaru Legacy sway bars &, links

Yes, the 2015 Subaru Legacy (BN/BS, known as the Liberty in Australia) is fitted with front and rear sway bars and links as standard. Technical sources including the Subaru Factory/Workshop Manual for the 2015 Legacy/Outback (Front Suspension and Rear Suspension sections via Subaru STIS) and the Subaru Electronic Parts Catalogue list the “stabiliser bar” assemblies and “stabiliser link” rods on both axles. These documents show the bar, D-bushes and brackets, and the ball-jointed links that connect the bar to the control arm or strut.

Sway bars &, links (also called stabiliser bars and drop links) tie the left and right suspension together to reduce body roll in corners. On the 2015 Legacy, they help keep the car flatter and more predictable, improving grip and steering feel without making the ride harsh. The links transmit suspension movement into the bar, the bar twists against its bushes to resist roll. When the links or bushes wear, the Legacy can feel a bit loose through bends and may clunk over bumps.

As part of routine servicing, it’s smart to inspect the sway bar D-bushes and links every 20,000–30,000 km, or whenever there are noises from the front or rear over rough roads. Look for perished rubber, cracked or oil-soaked bushes, torn link boots, play in the link joints, and loose brackets. A quick lever check with the vehicle safely lifted can reveal free play. Keeping tyres correctly inflated and aligned also helps reduce stress on the stabiliser system.

When replacement is due, change links in pairs on the same axle to keep handling balanced. Use quality parts (OE-style rubber bushes for comfort, or polyurethane for a firmer feel) and new self-locking nuts. Tighten all fasteners to factory torque with the car at normal ride height to avoid preloading the bushes. An alignment isn’t usually required after link or bush replacement unless other suspension work is done, but a road test is essential. If chasing flatter cornering, an upgraded bar can work well, though it may slightly increase firmness over sharp edges.

• Common signs of wear:
  • Clunks or rattles over speed humps and potholes
  • Excess body roll or vague turn-in
  • Visible bush cracking or split link boots
  • Uneven tyre wear linked to other suspension play

Popular questions about 2015 Subaru Legacy sway bars &, links

What are the symptoms of worn sway bar links or bushes on a 2015 Legacy?
Owners often report a light knock or rattle over small bumps, especially at lower speeds, and a slightly floaty feel in quick lane changes. Visual checks may show cracked D-bushes or torn link boots. If a link joint has play, the noise typically gets louder on rough roads.

If noises change when driving slowly over a speed hump at an angle, that’s a classic stabiliser-system clue. A workshop can confirm with a lever test while the car is safely supported.

Do you need a wheel alignment after replacing sway bar links or bushes?
Generally, no. The stabiliser bar and links don’t change static camber, caster, or toe on the 2015 Legacy. If only the links or D-bushes are replaced, an alignment isn’t usually required.

If other suspension parts are disturbed (struts, control arms, tie-rods), or if there’s uneven tyre wear, plan an alignment to keep steering sharp and tyre life strong.

How long do sway bar links last on a 2015 Legacy?
It varies with road conditions and driving style. Many last 80,000–150,000 km, but frequent corrugations, heavy loads, or aftermarket stiffer bars can shorten life. Inspect at each service and replace at the first sign of play or boot damage to protect tyres and keep handling tidy.
