Parts for your 2008 Toyota Mark x-Strut mounts

Are strutmounts used on the 2008 Toyota Mark X?

Short answer: no, proper strutmounts aren’t a thing on the 2008 Toyota Mark X (X120 series). Toyota’s own technical literature lists the front suspension as a double-wishbone design and the rear as multi-link for GRX120/GRX121 models. That setup doesn’t use a MacPherson strut, so there’s no rotating strut top with a bearing (what most people call a “strut mount”). Instead, the Mark X runs shock absorber assemblies with rubber support insulators at the top.

Technical sources referenced: Toyota New Car Features (Mark X X120) specifies “Front Suspension: Double Wishbone Type, Rear: Multi-link.” The Toyota Repair Manual for GRX120/121 covers “Front Shock Absorber Assembly” and “Rear Shock Absorber Assembly,” with no MacPherson strut or strut-top bearing section. The Toyota Electronic Parts Catalogue for GRX120 identifies “Front Shock Absorber Support Sub-Assembly” and upper/lower spring insulators—again, not a strutmount in the classic sense.

Why this matters: in a MacPherson setup, the strutmount carries vehicle weight, isolates vibration, and includes a bearing so the strut turns with the steering. On the Mark X’s double wishbone front, the steering pivot is handled by ball joints on the control arms, so there’s no need for a bearing-type strut top. The upper attachment is simply a rubberised support for the shock and spring, sometimes called a support insulator or shock mount.

What to service instead on a 2008toyotamarkx: think rubber and wear items around the shock assemblies. If there’s a thud over bumps, a tired-feeling front end, or perished rubber at the top of the shocks, it’s time for an inspection. A proper service will look at:

• Front and rear shock absorber support insulators (top mounts without bearings)
• Upper and lower coil spring insulators, dust boots, and bump stops
• Front lower/upper control arm bushes and ball joints (common noise sources)

A good rule of thumb for Aussie and Kiwi roads is to check these components around 100,000–150,000 km, sooner if there’s knocking, cupping on tyres, or unstable braking. Replace in axle pairs, use quality components, and get a wheel alignment after any suspension work. That’ll keep the Mark X riding quietly and tracking straight without chasing “strutmounts” that don’t actually fit this chassis.

FAQs

Does a 2008 Toyota Mark X have strutmounts?

No. The 2008 Mark X uses double wishbone front suspension and a multi-link rear, so it doesn’t run MacPherson struts or bearing-type strutmounts. Instead, it uses shock absorber support insulators at the top of the shock-spring assemblies to isolate noise and vibration.

What should be replaced instead of strutmounts on a 2008toyotamarkx?

Swap out the front and rear shock absorber support insulators, spring insulators, bump stops, and dust boots when they’re worn. Also check control arm bushes and ball joints, as they’re frequent culprits for clunks and vague steering on this platform.

How can someone spot a worn shock support insulator on a Mark X?

Listen for dull thuds over sharp bumps, feel for extra harshness or a loose front end, and look for cracked or collapsed rubber at the top of the shocks. There won’t be steering bind from a top bearing (because there isn’t one), but ride noise and impact harshness will creep in as the rubber ages.
