Parts for your 2013 Subaru Outback-Sway bars & links

2013 Subaru Outback sway-bars-&-links: what they do and when to replace them

Based on technical references including the Subaru Factory Service Manual for the 2013 Outback BM/BR (Front Suspension and Rear Suspension sections) and the Subaru genuine parts catalogue, this model is factory-fitted with front and rear stabiliser (sway) bars and stabiliser links. So yes—sway-bars-&-links are absolutely relevant to the 2013-subaru-outback.

The sway-bar is a torsion spring that ties the left and right suspension together to cut down body roll. The links (sometimes called drop links) join the bar to the control arm or strut, with D-bushes mounting the bar to the subframe. On a 2013 Outback, this setup helps it feel planted in corners, keeps steering more consistent when the wagon’s loaded with gear, and calms things down on bumpy Kiwi and Aussie roads.

As part of normal servicing, it pays to inspect the sway-bars-&-links every visit. Look for perished D-bushes, cracked or flogged-out link ball-joint boots, rust on the bar, and any play when the link is levered. Clunks over speed humps, a knock when turning into driveways, vague steering, or uneven tyre wear can all point to tired links or bushes. Coastal cars can see faster corrosion, so owners around the Tasman may want to be extra vigilant.

When replacing, doing links in pairs (left and right) keeps handling balanced. Use new lock nuts, hold the ball-stud with the correct hex/Torx to avoid tearing the boot, and tighten fasteners with the suspension at normal ride height to prevent bush preload. Most OE rubber D-bushes are installed dry, polyurethane bushes (if upgrading) usually need the specific grease supplied. A wheel alignment generally isn’t required for sway-bar work, unless the subframe or control arms have been loosened.

Heavy-duty bars and links can sharpen response for towing, roof loads, or country kilometres, but going too stiff may trade off rough-road compliance. Many owners stick with quality OE-equivalent parts and fresh bushes for a quiet, confident ride.

• Common signs it’s time: clunks/creaks over bumps, body roll feels worse, or visible bush/link wear.
• Service tip: inspect at each service, replace links and bushes before they hammer other suspension bits.

Popular questions about 2013-subaru-outback sway-bars-&-links

What are the signs the sway-bars-&-links need replacing?
Owners often notice a hollow clunk over speed humps, creaks at low speed, or extra body roll in roundabouts. A quick workshop check may reveal split link boots, loose ball joints, or D-bushes that are cracked or compressed.

Do sway-bar repairs need a wheel alignment?
Usually no. Changing links or D-bushes doesn’t affect alignment angles. If the subframe or control arms were loosened during the job, or if other suspension work is done at the same time, then an alignment is a good idea.

Should both sway-bar links be replaced at once?
Best practice is to replace links in pairs on the same axle. That keeps left-right response consistent and avoids chasing new noises from the older side. D-bushes are also typically renewed as a pair.
