Parts for your 2006 Toyota Mark x-Strut mounts

2006 Toyota Mark X strut mounts — are they used?

Short answer: no, the 2006 Toyota Mark X doesn’t use strut mounts. According to Toyota’s technical literature for the GRX120/121 series — specifically the New Car Features manual (Suspension section) and the Toyota Electronic Parts Catalogue (EPC, Group 48 Suspension & Axle) — the Mark X runs a double wishbone front suspension and a multi-link rear. That layout does not use MacPherson struts, so there’s no load‑bearing strut top with a steering pivot, i.e., no “strut mount” as found on many front‑wheel‑drive cars.

Why that matters: on a MacPherson system, the strut mount supports vehicle weight and acts as the upper steering bearing. On the Mark X’s double wishbone front end, the upper control arm sets the geometry and the damper doesn’t steer, it’s simply mounted with rubber cushions/insulators. At the rear, the multi‑link arrangement typically separates the spring from the damper (or uses a coilover that still doesn’t function as a steering strut), again doing away with a traditional strut mount.

What the Mark X actually has are shock absorber upper mounts/insulators (sometimes called cushions or bushes) and spring seats. The Toyota EPC lists these as insulators and bushings paired to the shock absorbers, not as a “front suspension support sub‑assembly” with a bearing — the usual naming for a true strut mount. So if someone’s chasing “strut mounts” for this model, they’re really after the shock top insulators or related rubber hardware.

Servicing tips for owners and workshops:

• Inspect front and rear shock absorber upper insulators/cushions for cracking, collapse, or separation, replace if perished.
• Check shocks for leaks and fade, on Aussie and Kiwi roads they commonly need attention somewhere between 80,000–150,000 km depending on use.
• Listen for clunks over sharp bumps, common culprits are shock top/bottom bushes, sway bar links, and lower control arm bushes.
• Always tighten suspension bushes with the vehicle at ride height, and replace dampers, insulators, and springs in axle pairs.
• After any suspension work, carry out a wheel alignment to protect tyres and keep the Mark X tracking straight.

If in doubt, quote the vehicle code (GRX120/121) and ask for front shock insulators/bushes or rear shock mounts/bushes — not strut mounts. That wording lines up with Toyota’s own manuals and parts listings.

Popular questions

Does a 2006 Toyota Mark X have strut mounts?
No. Toyota’s GRX120/121 New Car Features manual specifies double wishbone front and multi‑link rear suspension, which don’t use MacPherson struts. The Toyota EPC shows shock absorber insulators/bushes rather than strut mount bearing plates.

What should be replaced instead of “strut mounts” on a Mark X?
Look for front and rear shock absorber upper insulators/cushions, spring seats, sway bar links, and control arm bushes. These are the wear items that do the job people often assume a strut mount would handle.

What causes front‑end clunks on a Mark X if there are no strut mounts?
Typically worn shock top/bottom bushes, tired dampers, sway bar link ball joints, or lower control arm bushes. A proper inspection on stands with a pry bar and a road test will pinpoint the noise before parts are ordered.
