Parts for your 2013 Subaru Legacy-Sway bars & links

2013 Subaru Legacy sway bars & links: what they do and how to look after them

Yes, the 2013 Subaru Legacy is fitted with sway bars (also called stabiliser or anti-roll bars) and end links, front and rear. This is documented in the Subaru Service Manual for the 2013 Legacy/Outback (Suspension – Front/Rear sections, Stabilizer System), shown in the Subaru FAST parts catalogue as front and rear stabiliser bars with separate bushes and links, and mirrored by major aftermarket catalogues that list direct-fit links and bushes for this model. These technical references confirm sway bars and links are standard equipment on the 2013 Legacy.

On this Legacy, the sway bars and links team up to keep the car flatter and more settled through corners. The bar ties the left and right suspension together, when the body starts to lean, the bar twists and pushes back, reducing roll and sharpening steering feel. The end links are the little heroes that connect the bar to the strut or control arm. With Subaru’s Symmetrical AWD, a well-sorted sway bar setup helps the chassis feel balanced and predictable in both wet and dry conditions.

There’s no hard-and-fast replacement interval, but a quick check every 20,000–30,000 kilometres (or at regular services) is smart. Look for cracked or perished D-bushes on the bar, torn link boots, rust, or any free play. Road test for clunks over speed humps, dull knocks on rough patches, or extra body roll that wasn’t there before. A light squeak can be bushing noise, persistent clunking usually points to worn link ball joints.

When replacing, it’s best practice to do links in pairs on the same axle to keep handling even. Use new self-locking nuts, torque to factory spec, and tighten the bush clamps and link fasteners at normal ride height so the bar isn’t preloaded. An alignment typically isn’t required for sway bar or link work alone, but it’s worth checking if other suspension parts have been off. Rubber bushes are fitted from factory and aren’t greased, if choosing polyurethane upgrades, use the supplied grease and re-lube periodically to prevent squeaks.

Quality OEM-equivalent parts will restore factory feel. If chasing a bit more cornering bite, a larger rear bar or stiffer bushes can reduce roll and trim understeer, though ride may feel firmer over choppy roads. After any work, a quick shakedown drive and a re-check of torque once settled is a good habit.

• Typical lifespan: 80,000–150,000 km depending on roads and climate
• Common symptoms: clunks over bumps, increased body roll, vague turn-in
• Service tip: inspect at each service, replace in pairs on the same axle

FAQs

What are the signs my 2013 Legacy’s sway bar links are worn?
Most drivers notice a dull knock or rattle over potholes and driveway entries, more body roll in bends, or a slight delay before the front bites on turn-in. Visual checks may show torn dust boots, rust weeping from the ball joint, or obvious play when the link is moved by hand with the car safely lifted.

Do I need a wheel alignment after changing sway bar links or bushes?
Usually, no. The sway bar, its bushes, and the links don’t set wheel alignment angles. If you’ve also disturbed control arms, struts, or toe links, then an alignment is wise. If it’s just links and D-bushes, a road test and torque re-check is typically enough.

Should I replace both sway bar links at the same time?
Yes, doing them in pairs on the same axle keeps the handling balanced and avoids chasing a second repair soon after. If one side has worn out, the other is often not far behind, especially on vehicles that see rough roads.
