Parts for your 2018 Toyota Hilux-Strut mounts

2018 Toyota HiLux strut mounts — what they are, what they do, and when to swap them

Technical confirmation: The 2018 Toyota HiLux (N80 series, AN120/AN130) uses a front double‑wishbone suspension with a coil‑over shock absorber. In Toyota’s New Car Features and Repair Manual (Front Suspension section), the upper attachment is listed as the “Front Suspension Support Sub‑Assembly”/shock absorber insulator — commonly referred to in parts catalogues as a strut mount. It’s not a MacPherson strut with a steering bearing, but a rubber‑isolated top mount that secures the coil‑over to the body and damps noise and vibration. That means strut mounts are absolutely relevant and fitted to the 2018 HiLux.

On a 2018 Toyota HiLux, the strut mount (top mount) sits at the top of the front coil‑over, tying the shock and spring assembly to the chassis tower while isolating road harshness. Because the HiLux runs double wishbones, the mount doesn’t rotate for steering like a MacPherson bearing, instead, it’s a heavy‑duty rubber/metal assembly that keeps things quiet, tight, and aligned under load — from city kerbs to corrugations out bush.

Owners will often notice a tired top mount as a dull clunk over potholes, a creak when turning into driveways, or a shimmy on corrugated roads. Excess movement can let the spring seat shift and transmit vibration into the cabin. Left too long, it can accelerate wear of the shock and top hat hardware.

Best practice on a HiLux is to replace strut mounts whenever front shocks/struts are renewed, or at around 80,000–150,000 km depending on use. Vehicles that tow, carry trays, run bull bars, or see a lot of gravel typically need them earlier. Always do mounts in pairs, use quality components, and follow factory torque specs with the suspension supported at ride height.

• Listen for knocks, rattles, or rubber perishing during regular servicing.
• If fitting a lift or new coils, budget for new mounts and hardware — reusing crushed mounts can undo the benefits of fresh suspension.
• Use a proper spring compressor, the coil is under serious preload.
• After reassembly, get a wheel alignment — ride height changes can nudge camber and toe.

A fresh set of strut mounts keeps the HiLux feeling tight, reduces NVH, and protects new shocks — a small part that makes a big difference to how the ute behaves on rough Kiwi and Aussie roads.

Popular questions about 2018 Toyota HiLux strut mounts

How long do HiLux strut mounts typically last?

On sealed‑road commuters, many see 120,000–150,000 km. If the ute works hard — towing, mining sites, farm tracks, corrugations — expect closer to 80,000–100,000 km. Replace them whenever front shocks are done to avoid pulling the assembly apart twice.

What are common signs the strut mounts are worn on a 2018 HiLux?

Tell‑tales include a thud over sharp bumps, creaking at low speed over driveways, slight steering shimmy on rough surfaces, or visible rubber cracking around the top hat. If noise returns soon after new shocks, the old mounts were likely the culprit.

Do strut mounts need replacing when installing a lift or new front coils?

Strongly recommended. Lifted or heavier‑rate coils load the top mount more. Fresh mounts help control NVH and maintain proper seating. Pair the job with an alignment to dial in camber and toe after the ride height change.
