Parts for your 2005 Toyota Highlander-Strut mounts

2005 Toyota Highlander (Kluger) strut mounts — what they do and when to replace

Technical sources confirm the 2005 Toyota Highlander (sold as Kluger in Australia and New Zealand) uses MacPherson struts at the front and a strut-type rear suspension, which means strut mounts are absolutely fitted and relevant. This is documented in Toyota’s factory repair manual for the XU20 platform and shown in Toyota’s Electronic Parts Catalogue as the front “support sub‑assembly” and rear “strut mount/insulator.” Major aftermarket catalogues from suspension brands also list dedicated strut mount kits for this model year, front and rear.

On this 2005 Toyota Highlander, the strut mounts sit at the top of each strut, bolting the assembly to the body and providing a crucial cushion between metal components. Up front, they also incorporate a bearing so the strut can rotate smoothly with the steering. In day-to-day driving across Aussie and Kiwi roads, they soak up vibration and harshness, keep steering feel tidy, and help the car track straight. Without healthy mounts, even brand-new shocks can feel ordinary.

As part of servicing, it’s wise to inspect strut mounts any time the wheels, brakes, or struts are off—especially once the odometer is north of 150,000–200,000 kilometres or if the vehicle tows, carries loads, or regularly drives rough or corrugated surfaces. Rubber hardens and cracks with age, and bearings can develop notchiness. If one mount has failed, replacing them in axle pairs is the go-to approach to keep handling balanced.

• Common signs they’re tired: clunks over bumps, a creak or groan when turning the wheel, vagueness in steering, and feathered or uneven tyre wear.
• Best practice on replacement: fit quality mounts with integrated bearings (front), renew bump stops and dust boots, and follow torque specs with the spring properly compressed.
• After any strut or mount work: get a wheel alignment—camber and caster can shift as the new rubber sits higher.

DIYers should mark the top mount orientation, use new self-locking nuts where specified, and avoid lubricants on the rubber isolator. A quick post-service recheck for any settling noises is smart. Workshops will also eyeball the strut towers for elongation or corrosion and confirm that the mount studs and threads are clean and true.

Look after the strut mounts on a 2005 Highlander/Kluger and the ride stays quiet, steering stays precise, and tyres last longer—simple as that.

Popular question: How long do strut mounts last on a 2005 Toyota Highlander?

With mixed city and highway driving, many last 150,000–200,000 kilometres, sometimes more in mild conditions. Frequent gravel, heavy loads, or big temperature swings can shorten that. Inspect at every major service and any time the struts are out.

Popular question: Can worn strut mounts cause a steering clunk or vibration?

Yes. A collapsed rubber isolator or a notchy front bearing can produce clunks on bumps, shudder on turn-in, and light steering wander. If the noise changes when turning the wheel at low speed, the mount is a prime suspect.

Popular question: Should the strut mounts be replaced when fitting new struts?

Often, yes. Fitting new struts with old, hardened mounts can leave residual noise and average steering feel. Replacing mounts, bearings, bump stops, and boots together with the struts is a tidy, long-lasting fix—and an alignment afterwards seals the deal.
