Parts for your 2006 Toyota Mark x-Strut mounts

2006 Toyota Mark X: Do strut mounts apply?

Short answer: strut mounts aren’t used on the 2006 Toyota Mark X. Technical sources for the GRX120/121 platform — including Toyota’s New Car Features (NCF), the Toyota Repair Manual, and the Toyota Electronic Parts Catalogue (EPC) — specify a front double‑wishbone layout and a rear multi‑link setup. Because there’s no MacPherson strut at either end, there’s no traditional strut top mount with a steering bearing to service.

On a MacPherson‑equipped car, a strut mount sits at the top of the strut, carrying vehicle weight and acting as a pivot when you steer. The Mark X’s double‑wishbone front end locates the steering axis with upper and lower control arm ball joints, so the damper doesn’t rotate for steering and therefore doesn’t need a strut mount/bearing. Instead, the car uses shock absorber upper insulators/cushions and bushings that isolate noise and vibration without performing steering duties.

So while parts catalogues sometimes list “strut mounts” generically, what’s relevant for a 2006 Mark X are the upper shock insulators, bump stops, dust boots, and the usual control arm bushes and ball joints. If there’s a front‑end knock or a thud over bumps, owners should be thinking along those lines rather than a strut mount.

Good servicing practice on these cars focuses on condition rather than a fixed interval. Given Australasia’s mix of roads and climate, many workshops recommend a suspension check every 20,000–30,000 km or annually, whichever comes first. Look and listen for these tell‑tales:

• Clunks over speed humps or potholes (often upper shock insulators, stabiliser links, or control arm bushes).
• Creaks when turning at low speed (frequently ball joints or bushings, not a strut top bearing).
• Tyre feathering or inner‑edge wear (possible alignment or worn bushings).
• Floaty ride or longer stopping distances (tired dampers).

When refreshing the suspension, it’s smart to pair new shock absorbers with fresh upper insulators, bump stops, and boots. For the double‑wishbone front, inspect upper and lower control arm bushes and ball joints, at the rear, check multi‑link bushes and toe/camber arms. Genuine or quality aftermarket components, correct torque at ride height, and a proper four‑wheel alignment will keep the Mark X driving tight and tidy.

Technical reference basis: Toyota Mark X (GRX120/121) New Car Features, Toyota Repair Manual, and Toyota EPC identify double‑wishbone front and multi‑link rear suspension, confirming no MacPherson strut — and therefore no conventional strut mounts — on the 2006 model.

Does the 2006 Toyota Mark X have strut mounts?

No. The GRX120/121 Mark X uses a double‑wishbone front end and a multi‑link rear, so it doesn’t run MacPherson struts. That means there’s no strut top bearing or classic “strut mount” to replace.

Instead, it uses shock absorber upper insulators/cushions, bump stops, and boots. Steering loads go through the ball joints in the control arms, not through a strut top.

What should be replaced instead of strut mounts on a Mark X?

When chasing knocks or freshening the suspension, look at front and rear shock absorbers, upper shock insulators, bump stops, dust boots, stabiliser (sway bar) links and bushes, and the control arm bushes/ball joints.

Pairing new dampers with new insulators and an alignment is a tidy way to restore ride and handling without chasing a part the car doesn’t have.

How can someone tell if their Mark X needs suspension attention?

Common signs include clunks over bumps, creaks at parking speeds, uneven tyre wear, vague turn‑in, or a floaty ride. Any of those point to wear in dampers, insulators, bushes, or joints.

A quick workshop check every 20,000–30,000 km is a good shout for Aussie and Kiwi conditions, followed by replacement of worn components and a proper wheel alignment.
