Parts for your 2019 Subaru Impreza-Sway bars & links

2019 Subaru Impreza sway-bars-&-links: what they do and when to replace them

Technical sources confirm the 2019 Subaru Impreza is fitted with sway bars (stabiliser bars) and end links front and rear. The Subaru Service Manual for 2019MY Impreza (Front Suspension and Rear Suspension sections) details the stabiliser bar, D‑bushes and stabiliser links as standard components, and the Subaru parts catalogue lists corresponding OEM parts for both axles. On the Subaru Global Platform used by this model, these components are integral to body control and cornering stability, so sway-bars-&-links are absolutely relevant to this vehicle.

On the 2019 Impreza, the sway bars connect left and right suspension to reduce body roll when cornering. The links (short arms with ball joints or bush joints) tie the bar to the strut/control arm, letting the bar twist as the car loads up. The result is flatter, more confident handling and more consistent tyre contact — handy on winding Kiwi and Aussie roads and in the wet.

Servicing-wise, they’re simple but worth a regular look. During routine services, a quick inspection of the D‑bushes on the bar and the link joints can prevent annoying knocks and vague steering feel.

• What to look for: split or perished D‑bushes, oily or torn link boots, free play at the link joints, and witness marks from the bar “walking” in the bushes.
• Typical symptoms: clunks over speed humps, increased body roll, and a slightly skittish or delayed response in quick lane changes.
• Inspection cadence: have them checked at each service (about every 10,000–15,000 km). Many last well past 80,000–120,000 km, but harsh roads can shorten that.
• Replacement tips: replace links in axle pairs, torque fasteners to factory spec with the suspension at normal ride height, and choose bush materials (OEM rubber or uprated polyurethane) to suit how you drive. Avoid petroleum-based lubricants on rubber bushes.
• After the job: a wheel alignment isn’t usually required for sway bars alone, but it’s smart if other suspension work was done at the same time.

If the aim is simply to bring the car back to quiet, solid factory behaviour, OEM-style sway bars and links are the go. If chasing a bit more roll control, a thicker bar may help, but balance front-to-rear is key — too stiff at one end can nudge the handling towards understeer or oversteer. For everyday commuting and weekend trips, fresh bushes and quality links typically deliver the biggest bang for buck.

FAQs

Do all 2019 Subaru Impreza models have sway bars and links?
Yes. For the 2019 model year in Australia and New Zealand, the Impreza is built on Subaru’s Global Platform with stabiliser (sway) bars and links fitted front and rear. This is documented in the Subaru Service Manual and reflected in the OEM parts catalogue.

What are the tell-tale signs my sway bar links or bushes are worn?
Common signs include a dull knock over speed humps or potholes, extra body roll in corners, and a slightly vague or delayed steering feel. Visual checks often show cracked D‑bushes or torn link boots, and a pry-bar test can reveal excess play at the link joints.

How often should sway bar bushes and links be replaced?
There’s no fixed interval. Have them inspected at every service (around 10,000–15,000 km). On typical roads they can last 80,000–120,000 km or more, but frequent gravel use or harsh urban bumps can bring that forward. Replace in pairs on the same axle for consistent handling.
