Parts for your 2004 Toyota Highlander-Suspension bushes

2004 Toyota Highlander (Kluger) suspension bushes

Suspension bushes are definitely used on the 2004 Toyota Highlander (also sold as the Kluger in AU/NZ). Toyota’s factory Repair Manual sections for Front and Rear Suspension, the Toyota Electronic Parts Catalog (ACU2#/MCU2# series), and well-known parts catalogues from SuperPro, Whiteline and Moog all list front lower control arm bushes, stabiliser (sway) bar D‑bushes and links, rear control/trailing arm bushes and subframe/beam bushes for this model. So suspension bushes are a relevant, fitted service item on the 2004 Highlander/Kluger.

On this Highlander, the bushes are the quiet achievers that keep things smooth, tight and predictable. Pressed into control arms and mounted on sway bars and the rear arms, they isolate noise and vibration while allowing just the right amount of movement. That flex helps the tyres stay planted, keeps alignment stable under braking and cornering, and takes the sting out of rough Aussie and Kiwi backroads.

Owners will usually notice worn bushes as dull thuds over bumps, vague steering, wandering on the motorway, brake shimmy or uneven tyre wear. Because the 2004 Highlander runs rubber bushes from factory, age, heat and road grime eventually harden or crack them. Coastal air and gravel corrugations can speed that up.

As part of routine servicing, it’s smart to inspect the bushes annually or every 20–30,000 km. A torch and pry bar check for cracking, torn lips, oil swelling and excessive movement goes a long way. When replacing, many choose complete control arms for ease, pressing individual bushes is fine if you’ve got the tooling. Always torque the arm bolts at normal ride height so the rubber isn’t pre‑twisted, and book a wheel alignment if any arm or camber/caster‑affecting bush is changed.

• Rubber vs polyurethane: OE‑style rubber keeps it comfy and quiet, quality polyurethane sharpens response and lasts longer, but can add a touch more vibration. Grease poly bushes with the supplied lube.
• Replace in pairs side‑to‑side to keep handling balanced.
• Front sway bar D‑bush squeaks and clunks are common and cheap to sort—worth doing with links if they’re tired.

Done right, fresh bushes make a 2004 Highlander feel younger, track straighter and wear its tyres more evenly—nice win for daily duties and long family trips alike.

Popular questions

How often should suspension bushes be replaced on a 2004 Highlander?
There’s no fixed interval. Have them inspected every service or 20–30,000 km. Replace when you see cracks, tears, oil‑swollen rubber, or feel clunks, wander or uneven tyre wear. Driving on rough roads or towing can bring replacement forward.

Do I need a wheel alignment after replacing bushes?
Yes if you’ve changed any control arm or bush that affects geometry (front lower arm, rear toe/camber arms). Even when only sway bar bushes are done, it’s still a good idea to check alignment to protect tyre life.

Is it better to press in new bushes or fit complete arms?
Both approaches work. Pressing bushes is cost‑effective if you’ve got the tools and the arm is in good nick. Complete arms save time and often include new ball joints and bushes—great when the original arm is worn or corroded.
