Parts for your 2018 Toyota Mark x-Strut mounts

2018 Toyota Mark X strut-mounts — are they used?

Technical sources for the GRX130-series Toyota Mark X (2016–2019) state the car runs a double wishbone front suspension and a multi-link rear. This is documented in Toyota’s New Car Features/Repair Manual for GRX130, the Japanese-market Mark X brochure specification sheets for the late-model facelift, and Toyota Global product materials. Because the front end is double wishbone, the spring/damper unit does not act as a structural member to locate the wheel like a MacPherson strut does. That means a traditional “strut mount” and bearing assembly is not used on the 2018 Toyota Mark X.

Instead, the Mark X uses a shock absorber upper insulator/mount (sometimes called a top support) that isolates noise and vibration but doesn’t carry side loads or provide steering rotation. The wheel location and alignment are managed by the upper and lower control arms and their bushes and ball joints. The rear multi-link is also a non-strut layout, so it uses damper and spring mounts rather than strut mounts. When parts catalogues list “strut-mounts” for this vehicle, it’s typically a generic label for the shock absorber upper insulator.

What owners and technicians should service on a 2018 Mark X instead of “strut-mounts” comes down to the usual wear items in a double wishbone/multi-link setup. Regular checks keep the ride quiet and the handling sharp, and help tyres wear evenly.

• Front shock absorber upper insulators/mounts, dust boots and bump stops
• Upper and lower control arm bushes and ball joints
• Stabiliser (sway bar) links and bushes
• Rear shock absorber upper mounts/insulators and rear arm bushes
• Wheel alignment after any arm, bush or mount replacement

Practical advice: inspect these components every 20,000 km or 12 months, or sooner if there are clunks over bumps, steering shimmy, uneven tyre wear, or a thud on sharp edges. Replace mounts/insulators if the rubber is cracked, delaminated, or if there’s play or knocking. Tighten damper top nuts to spec and always torque control arm bolts at normal ride height to avoid preloading the bushes. Quality OEM or genuine parts are recommended for noise control and longevity.

Popular questions about 2018 Toyota Mark X strut-mounts

Does a 2018 Toyota Mark X have strut-mounts?
No. The Mark X (GRX130) uses a double wishbone front and multi-link rear suspension, so there’s no MacPherson strut or strut-mount/bearing assembly. It uses shock absorber upper insulators/mounts instead.

My Mark X clunks over bumps — is that a failed strut-mount?
Because it doesn’t have strut-mounts, the usual suspects are worn shock absorber mounts/insulators, stabiliser links/bushes, or control arm bushes/ball joints. A visual inspection for cracked rubber, looseness, or a loose damper top nut will pinpoint the cause.

Can I fit aftermarket “strut-mounts” from another Toyota (e.g., Camry) to my Mark X?
No. Those parts suit MacPherson-strut cars. The Mark X requires components listed as shock absorber upper insulators/mounts specific to GRX130, along with the correct bushes and hardware for its double wishbone/multi-link layout.
