Parts for your 2015 Subaru Impreza-Sway bars & links

2015 Subaru Impreza sway-bars-&-links: what they do and how to look after them

Yes, the 2015 Subaru Impreza is fitted with front and rear sway-bars-&-links (also called stabiliser bars and links). This is confirmed in Subaru’s 2015MY Impreza (GJ/GP) workshop manual under Front/Rear Stabilizer sections, as well as Subaru’s OEM parts catalogues and widely used aftermarket catalogues that list front and rear stabiliser bars, D-bushes, and end links for this model. These technical sources make it clear the system is standard equipment across the range.

On the 2015 Impreza, the sway-bar ties the left and right suspension together to control body roll in corners. The links connect the bar to the suspension arms or struts, letting the bar twist as the car leans. The result is flatter, more confident cornering and better grip when the road gets twisty or when dodging a roo at highway speeds.

For servicing, sway-bars-&-links don’t have a fixed replacement interval, but they do like regular inspections. At each service or around every 10,000–15,000 km, a quick check of the front and rear bar D-bushes and the end links is smart. The OE end links are sealed ball-joint style, so there’s no greasing to do—when the boots split or play develops, replacement is the go. The bar’s D-bushes are wear items, if they’re perished, loose on the bar, or squeaking, they should be replaced. Polyurethane bushes may need periodic lubrication with the correct grease, rubber bushes don’t.

• Common symptoms: clunks over speed humps, rattles on rough roads, extra body roll, vague steering, or visible torn link boots.
• Replacement tips: use new self-locking nuts, torque the links and bracket bolts with the suspension at ride height, and re-check fasteners after a short bedding-in period.
• Safety note: driving with a failed link or bar isn’t immediately catastrophic, but handling will be compromised—best to sort it promptly.

Depending on roads and load, many Imprezas see links and D-bushes last anywhere from 80,000 to well over 150,000 km. If the car lives on corrugated or potholed tarmac, expect earlier attention. A wheel alignment isn’t usually required for sway-bar work alone, but if other suspension parts are touched, an alignment check is a good idea to protect tyres and get the steering feel back on song.

Popular questions about 2015 Subaru Impreza sway-bars-&-links

How often should sway-bar links or bushes be replaced?
There’s no strict kilometre rule because it depends on road quality and driving style. Most owners just inspect at each service and replace on condition—when there’s play, noise, or perishing. It’s common to see links and D-bushes last 80,000–150,000 km, but rough roads can shorten that.

What are the tell-tale signs they’re worn?
Clunks over speed humps, rattles on broken seal, extra body roll, and a slightly floaty front end are classic. A visual check often shows split dust boots on the link ball joints or cracked, shiny, or loose D-bushes on the bar.

Is an alignment needed after replacing sway-bar links?
Usually no, because the bar and links don’t set wheel angles. If other suspension parts are disturbed, or if the steering feels off afterwards, getting an alignment is a smart precaution to keep tyre wear even and the car tracking straight.
