Parts for your 2008 Toyota Mark x-Strut mounts

2008 Toyota Mark X Strut Mounts — Are They Used?

Short answer: no, the 2008 Toyota Mark X doesn’t use strut mounts. Technical literature for the first‑generation Mark X (GRX120/121/125) specifies a double wishbone front suspension and a multi‑link rear—see Toyota’s New Car Features for Mark X and the Toyota Global press information for the model’s launch, both of which call out the double‑wishbone front layout. The factory repair manual for the GRX120 platform also details a front shock absorber with coil spring that’s located by upper and lower control arms, not a MacPherson strut. That means there’s no strut top bearing or “strut mount” in the MacPherson sense.

Why that matters: in a MacPherson setup, the strut mount carries vehicle weight, isolates noise and vibration, and includes a bearing that lets the strut turn with the steering. A double wishbone system like the Mark X uses upper and lower arms to control camber and caster, so the damper doesn’t act as a steering pivot. Up top, the Mark X uses a simple shock absorber upper support/insulator and spring seat rather than a strut mount with a bearing. So if someone’s chasing “strut mounts” for a 2008 Mark X, the correct parts to look for are the front shock absorber upper insulator/support, upper spring seat, bump stop and dust boot.

Typical symptoms that lead people to search for “strut mounts”—clunks over bumps, dull thuds, or front‑end harshness—on a Mark X usually come from wear in these areas instead:

• Front shock absorber upper insulators and spring seats (cracked or collapsed rubber)
• Stabiliser (sway bar) links and bushes
• Lower control arm bushes and ball joints
• Top hats/isolators on the rear shocks (multi‑link rear)

Good servicing habits for a Mark X front end:

1. Inspect shocks, upper insulators and sway bar links every 20,000–30,000 km or at each service if driven on rough roads.
2. Replace upper insulators if the rubber is perished, cracked, or noticeably compressed, renew the dust boot and bump stop at the same time.
3. Use quality OEM or reputable aftermarket components to keep noise, vibration and harshness in check.
4. Get a wheel alignment after any suspension work—camber and caster are controlled by the arms, so alignment matters.
5. Torque all fasteners to the specs in the GRX120 repair manual to avoid squeaks and premature wear.

Popular questions about 2008‑Toyota‑Mark‑X strut mounts

Does a 2008 Toyota Mark X have strut mounts?
No. The Mark X uses a double wishbone front suspension, so there’s no MacPherson‑style strut mount or rotating top bearing. Instead, it has a shock absorber with an upper insulator and spring seat that don’t steer with the wheels.

What part should be replaced instead of a strut mount on a Mark X?
If there’s knocking or rubber deterioration at the top of the front shock, look for the front shock absorber upper insulator/support, upper spring seat, dust boot and bump stop. Also check stabiliser links and lower control arm bushes—they’re common noise makers on these cars.

Do you need an alignment after replacing the front shock or upper insulator?
Yes, it’s a smart move. Although the damper isn’t the steering pivot, removal and refit can nudge arm positions. A wheel alignment ensures correct camber, caster and toe so tyre wear and road feel stay tidy.
