2005 Toyota Highlander Control Arms — What They Do and When to Replace Them

Yes, the 2005 Toyota Highlander uses control arms. The Toyota Repair Manual for the XU30 platform and the Toyota Electronic Parts Catalogue list front lower control arms (left and right) with pressed-in rubber bushes and a separate lower ball joint, plus rear lateral control arms/links as part of the multi-link rear suspension. Independent guides such as the Haynes manual for 2001–2007 Highlander/Kluger echo the same setup, so control arms are absolutely relevant for this model.

On this Highlander, the front lower control arms keep the hub located while the MacPherson strut handles damping. The arms pivot on rubber bushes at the subframe and connect to the steering knuckle via the lower ball joint. Out back, the lateral “control” arms keep the wheel pointed straight and manage toe and camber through the suspension stroke. Together, they keep tyres planted, steering true, and ride comfort tidy.

Over time, bushings harden, crack or oil-soak, and ball joints can loosen up. That shows up as clunks over speed bumps, a shimmy on braking, vague steering, or uneven tyre wear. On Aussie and Kiwi roads, it’s common to see front rear-bush wear around 150,000–250,000 km, earlier if the vehicle tows or sees lots of corrugations.

Good servicing habits help:

• Inspect every 20,000 km or 12 months for split or fluid-leaking bushes, torn dust boots, and ball joint play.
• If replacing, do both sides on the axle so handling stays balanced.
• Torque all pivot bolts at normal ride height to avoid preloading the bushes.
• Book a wheel alignment straight after any arm, bush, or ball joint work.
• Consider fresh sway bar links and lower ball joints while you’re there, labour overlaps nicely.
• Avoid petroleum-based sprays on rubber, they can swell and weaken bushes.

Choosing parts comes down to priorities. Genuine Toyota arms and bushes give OE feel and longevity. Quality aftermarket arms can be cost-effective, while polyurethane bushes sharpen response but can add a bit more noise and vibration. If bolts are rusty, have new cam bolts and nuts on hand—seized hardware is common on vehicles of this age.

Bottom line: keeping the Highlander’s control arms in good nick preserves tyre life, braking stability, and that easygoing steering feel these SUVs are known for. Always follow the Toyota service manual for procedures and torque values, or have a trusted technician handle the job.

Popular questions about 2005 Toyota Highlander control arms

Does the 2005 Highlander have rear control arms as well as fronts?

Yes. The rear suspension uses multiple lateral control arms/links to manage toe and camber, working with the trailing arm and strut. They’re not the same shape as the big front lower arms, but they serve the same job—controlling wheel position through the suspension travel.

How long do control arm bushes last on a 2005 Highlander?

Many see 150,000–250,000 km, but life varies with road conditions, load, and age. Look for cracked rubber, off-centre sleeves, or oily, swollen bushes. If there’s a thud on take-off or braking, or tyres are wearing oddly, it’s time for a closer look.

Do I need an alignment after replacing control arms?

Absolutely. Any time you change control arms, bushes, or ball joints, the alignment can shift. A proper alignment brings steering back on centre, sets toe and camber, and protects tyre life.
