Parts for your 2012 Toyota Mark x-Strut mounts

Are strutmounts used on the 2012 Toyota Mark X?

Short answer: no. Referencing Toyota’s technical literature for the X130-series Mark X (New Car Features manual and parts catalogue) along with model specs published in the Japanese-market brochures, the 2012 Toyota Mark X runs a double-wishbone front suspension and a multi-link rear. Because it does not use MacPherson struts, the vehicle isn’t fitted with conventional strutmounts (the bearing-type top mounts you’d find on many front-drive cars).

A “strutmount” is specific to MacPherson strut setups, where the spring and damper form a structural member that also steers. The top mount contains a bearing and isolator to handle steering loads and road shock. On the 2012 Mark X, steering and cornering loads are carried by the upper and lower control arms in the double-wishbone assembly. The shock absorber has an upper insulator/bush and hardware, but not a strutmount with a steering bearing.

This layout is used on the Mark X to deliver precise camber control and a more refined ride, benefiting a rear-wheel drive sedan tuned for balance and comfort. With the double wishbone, the body doesn’t rely on a strut tower to guide the wheel, so there’s no need for a strut top bearing assembly.

What to service instead of “strutmounts”? For the front end, focus on upper and lower control arm bushes and ball joints, shock absorber upper insulators, sway-bar links and bushes. At the rear, check the multi-link arm bushes, damper mounts and stabiliser links. If there’s a knock over bumps, vague steering, or uneven tyre wear, those are prime suspects, not strutmounts.

Helpful tips for workshops and owners:

• Inspect suspension bushes, ball joints and damper mounts every 20,000–30,000 km or during routine servicing.
• Replace rubber insulators and bushes in axle pairs to keep handling even left to right.
• Tighten arm bolts at normal ride height to avoid preloading new bushes.
• Book a wheel alignment after replacing control arms or dampers.
• Be wary of listings that say “Mark X strutmounts” — these often mean shock top insulators or aftermarket coilover top plates.

Track or custom coilover setups may add “pillow-ball” or camber-plate style top mounts, but that’s a modification, not factory fitment. For a stock 2012 Mark X, strutmounts simply aren’t part of the design.

FAQs about 2012toyotamarkx strutmounts

Does a 2012 Toyota Mark X have strutmounts?

No. The 2012 Mark X (X130) uses a double-wishbone front and multi-link rear suspension, so it doesn’t have MacPherson strut top mounts with bearings. The front shock has an upper insulator, but that’s not a steering strutmount.

If a parts site lists “strutmounts” for this car, it’s usually a generic term for shock top insulators or aftermarket coilover top plates rather than an OE strut top.

What should be serviced instead of strutmounts on a 2012 Mark X?

Focus on control arm bushes and ball joints, shock absorber upper insulators, and sway-bar links and bushes up front. At the rear, inspect multi-link arm bushes, damper mounts and stabiliser links.

Clunks over bumps, steering shimmy, or irregular tyre wear point to wear in those components. Replace in pairs and get an alignment after major suspension work.

Can coilovers add “strutmounts” to a Mark X?

Aftermarket coilovers can include adjustable top mounts (often pillow-ball/camber plates). These are part of the coilover assembly and differ from factory MacPherson strutmounts.

If fitting coilovers, follow the kit’s torque specs, use quality top plates, and re-align the car. For stock suspension, stick with OE-style shocks, insulators and bushes.
