Parts for your 2004 Toyota Highlander-Sway bars & links

2004 Toyota Highlander (Kluger) sway bar links — relevance, purpose, and service tips

Yes — sway bar links are fitted to the 2004 Toyota Highlander (known as Kluger in Australia and New Zealand). Technical sources including Toyota’s Repair Manual (TIS) for the XU20 platform list both Front Suspension – Stabiliser Bar – Stabiliser Link and Rear Suspension – Stabiliser Bar – Stabiliser Link procedures, complete with inspection and torque guidance. Toyota’s Electronic Parts Catalogue (EPC) also shows dedicated front and rear stabiliser link assemblies for 2004 Highlander/Harrier models (ACU2#, MCU2#), and Toyota’s New Car Features documentation describes front and rear stabiliser bars used to reduce body roll, which are connected to the suspension by these links.

On this model, the stabiliser (sway) bar links connect the sway bar to the suspension arms or struts, helping the bar do its job of reducing body roll and sharpening steering response. Each link uses ball-jointed ends to allow up-and-down suspension travel while transmitting roll-resisting force from the bar. When the links are healthy, the Highlander/Kluger feels settled in corners and composed over bumps.

Because the links live down in the spray, they cop water, grit, and road salt, so the joints and boots can wear or split over time. Typical signs it’s time to replace them include a light clunk or rattle over small bumps, a knock when turning into driveways, and a slight increase in body roll. They won’t usually cause tyre wear on their own, but they can make the front end feel a bit loose or chattery.

There’s no fixed replacement interval, many last well past 100,000 km, but rough roads, towing, and coastal corrosion can shorten their life. As part of regular servicing, it’s smart to inspect them every 10,000–15,000 km: check for torn dust boots, rust at the studs, and any free play by levering the link gently while the vehicle is safely supported. If the boots are split or there’s noticeable play, replacement is the go.

When replacing, do both sides on the same axle for even handling. Choose quality links (sealed or greaseable, depending on preference). Soak the old hardware with penetrant, and use the correct hex/Torx provision on the stud to stop it spinning. Tighten fasteners to the factory torque with the suspension at normal ride height to avoid preloading the bushings. It’s also worth checking the stabiliser bar mounting bushes at the same time, worn bushes can mimic link noise. A wheel alignment isn’t normally required after link replacement, as no alignment angles are disturbed, but a quick road test to confirm the rattle’s gone and the steering feels right is essential.

• Common signs it’s time: clunks over bumps, increased body roll, split boots, visible play.
• Handy tips: replace in pairs, torque at ride height, inspect sway bar bushes, and road test.

Popular questions about 2004 Toyota Highlander sway bar links

How do you know the sway bar links are worn on a 2004 Toyota Highlander?

Listen for a light clunk or rattle over small, repeated bumps and a knock when turning into driveways or speed humps. You might also feel a touch more body roll or front-end chatter. A visual check often shows torn dust boots, corrosion on the studs, or free play at the ball joints when levered.

Because worn links can sound like tired stabiliser bar bushes, inspect both. If the noise disappears when the links are disconnected during diagnosis, that’s another strong indicator the links are the culprit.

Do you need a wheel alignment after replacing sway bar links?

No, an alignment isn’t typically required after sway bar link replacement on a Highlander/Kluger because the links don’t change camber, caster, or toe. If other suspension parts were also disturbed, or if tyres show uneven wear, an alignment check is sensible.

Should you replace the stabiliser bar bushes at the same time?

It’s a good idea to assess them together. Worn bushes can squeak or thud and often age alongside the links. If the bushes are cracked, squashed, or oily, replace them with the links to restore quiet operation and crisp roll control in one hit.
