Parts for your 2006 Toyota Highlander-Strut mounts

2006 Toyota Highlander (Kluger) strut mounts — what they do and when to replace them

Strut mounts are absolutely fitted to the 2006 Toyota Highlander (sold as Kluger in AU/NZ). The Toyota Repair Manual for this generation (front and rear MacPherson strut suspension) specifies a “Front Suspension Support Sub‑Assembly” and “Rear Suspension Support Sub‑Assembly” — Toyota’s term for the strut mount — in the chassis/suspension sections. The Toyota Electronic Parts Catalogue and major fitment catalogues from suspension manufacturers also list dedicated front and rear strut mounts for 2001–2007 Highlander/Kluger. That makes strut mounts relevant, serviceable parts on this model.

On this Highlander, each strut mount sits at the top of the strut assembly, tying the strut to the body. It does two big jobs: it isolates road vibration and noise with a rubber insulator, and it provides a smooth bearing surface (on the front) so the strut can rotate as the wheels steer. When they’re healthy, the ride feels settled and quiet, and steering is consistent.

Owners will get the most from their 2006 Highlander by checking the strut mounts during routine services. A quick inspection every 20,000–30,000 km is sensible: look for perished rubber, cracking or separation, torn dust boots on the strut, and play or roughness in the front mount bearing. Any clunks over small bumps, a thud when turning into driveways, or a groan/creak while steering are classic tells. Uneven tyre wear or vague steering can also point to tired mounts.

Replacement tips that suit Aussie and Kiwi conditions:

• Replace mounts in axle pairs (both fronts or both rears) to keep handling even.
• Use quality OE‑equivalent mounts, cheap rubber can collapse early.
• Front mounts include a bearing — if it’s gritty, don’t reuse it.
• Always compress springs safely, the mount is under serious preload.
• Torque the centre nut and top mount hardware to spec, don’t rattle‑gun blindly.
• Get a wheel alignment after front strut or mount work, geometry can shift.

Many Highlanders in local fleets see 120,000–180,000 km before mounts show obvious symptoms, but harsh roads, heavy loads, or lifted suspension can bring that forward. If the vehicle feels crashy over corrugations or the steering chatters on lock, it’s time to book an inspection. Fresh strut mounts can transform cabin refinement and steering feel without changing the overall ride height or spring rate.

Popular questions about 2006 Toyota Highlander strut mounts

What are the signs of worn strut mounts on a 2006 Highlander/Kluger?

Common signs include a dull clunk over small bumps, creaks or groans while turning the steering at low speed, steering that won’t self‑centre smoothly, and a jittery, noisy ride on coarse chip. You might also see uneven tyre wear or notice the bonnet area shuddering on rough roads.

Do you need a wheel alignment after replacing strut mounts?

Yes, especially if the front struts were removed. Changing mounts can alter camber and caster slightly, and disturbing the strut-to-knuckle joint nearly always affects toe. A proper alignment protects tyre life and restores straight‑line stability.

How long do strut mounts typically last on this model?

On sealed suburban roads, many last 120,000–180,000 km. Frequent gravel, heavy loads, towing, or larger wheels can shorten that. Inspect at regular service intervals and replace when noise, play, or rubber deterioration shows up rather than chasing kilometres alone.
