2018 Toyota Mark X Struts — Purpose, Care and Replacement

Yes, struts are relevant on the 2018 Toyota Mark X. Technical sources including the Toyota Mark X GRX130-series repair manual (Front Suspension – MacPherson Strut), the Toyota Electronic Parts Catalogue for GRX130/133/135, and aftermarket application catalogues from KYB and Monroe all confirm a MacPherson strut front suspension and a multi-link rear with separate shocks. So when talking “struts” on a 2018 Mark X, we’re talking about the front end.

The front struts do a lot more than just soak up bumps. Each strut is a shock absorber housed within a structural assembly that supports the spring, locates the wheel, and helps control camber while steering and braking. That’s why tired struts can show up as vague steering, longer stopping distances, or uneven front tyre wear. On a Mark X, healthy front struts keep the nose planted, steer feel crisp, and ride quality tidy on rough Kiwi and Aussie roads.

Servicing-wise, struts aren’t a set-and-forget item. They should be inspected every service or at least every 20,000 km for leaks, dented housings, damaged dust boots, sagging springs, and worn top mounts/bearings. Replacement timing varies with use and road conditions, but many owners see best results replacing in pairs somewhere around 80,000–120,000 km, or sooner if symptoms crop up.

• Common signs it’s time: nose-diving under brakes, floaty or bouncy ride, clunks over speed humps, steering wobble, and feathered inner or outer edges on front tyres.
• Good practice when replacing: fit quality struts with new bump stops, dust boots, and top mounts, replace coil springs if sagging or rusty, always follow torque specs with the vehicle at normal ride height.
• Finish with a four-wheel alignment. Camber and toe can shift when the struts come out, so an alignment protects your tyres and restores proper handling.

A fresh set of front struts brings the Mark X back to its best—better grip over corrugations, flatter cornering, and more confident braking. Pair them with good tyres and a tidy alignment and the big Toyota feels composed, quiet, and predictable, just as it should.

Popular questions

Does the 2018 Mark X have rear struts?
The rear of the 2018 Mark X uses a multi-link setup with separate shock absorbers and springs, not MacPherson struts. Only the front suspension uses struts on this model.

How often should front struts be replaced on a 2018 Mark X?
There’s no fixed interval. Have them inspected every service, many owners replace between 80,000 and 120,000 km depending on road conditions and load. If there’s leakage, poor ride control, or uneven tyre wear, it’s time.

Do you need a wheel alignment after replacing front struts?
Absolutely. Removing and refitting struts changes camber and toe. A proper four-wheel alignment after installation safeguards tyre life and restores sharp steering.
