Parts for your 2005 Toyota Mark x-Strut mounts

2005 Toyota Mark X strut-mounts — are they used, or not?

Short answer: strut-mounts aren’t used on the 2005 Toyota Mark X (GRX120/121). That model runs a double wishbone front suspension and a multi-link rear, not a MacPherson strut setup. Because there’s no MacPherson strut, there’s no strut top bearing or traditional “strut mount” to replace. Instead, it uses shock absorber upper supports/insulators and related rubber hardware.

Technical sources referenced for this conclusion include Toyota’s New Car Features (NCF) manual for GRX120/121 (model year 2004–2009) describing the front suspension as double wishbone and the rear as multi-link, the Toyota Repair Manual for GRX120 (front suspension section identifies a double-wishbone type with a shock/coil unit and an upper support insulator rather than a strut bearing mount), and Toyota’s Electronic Parts Catalogue (EPC) for GRX120 which lists components under “Front spring and shock absorber (double wishbone type)” such as the upper insulator/support and cushions, not a strut mount with bearing.

Why no strut-mounts on a Mark X? In a MacPherson strut car, the strut itself locates the hub and turns with the steering, so it needs a top mount with an integrated bearing. The Mark X’s double wishbone front end locates the hub with upper and lower control arms. The shock doesn’t steer or locate the hub, so it only needs a rubberised upper support/insulator to isolate noise and vibration—not a strut mount with a bearing.

If someone’s chasing “strut-mount” parts for a 2005 Toyota Mark X, what they likely need are: front shock absorber upper insulators/supports, upper spring seats, dust boots and bump stops, or front control arm bushings/ball joints. At the rear multi-link, the shock top mounts are also insulators rather than strut mounts. Typical service advice for Aussie and Kiwi roads: replace tired upper insulators when fitting new shocks, renew boots and bump stops together, and torque control arm bushings at normal ride height. An alignment’s smart after any control arm, cam bolt, or significant suspension work, even if shocks alone are changed.

FAQs — 2005 Toyota Mark X strut-mounts

Does a 2005 Toyota Mark X have strut-mounts?

No. The Mark X uses double wishbone front suspension and multi-link rear, so there’s no MacPherson strut or strut top bearing. Instead, it has shock absorber upper supports/insulators that don’t rotate with steering.

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

Look for front shock upper insulators/supports, upper spring seats, dust boots and bump stops. Also common are front lower/upper control arm bushings and ball joints, and sway bar links and bushes—these are typical culprits for knocks and vibration.

Do I need a wheel alignment after suspension work on a Mark X?

After replacing control arms, cam bolts, or anything affecting geometry—yes, absolutely. If you only replace shocks and upper insulators, alignment may not shift much, but it’s still recommended to keep tyre wear even and steering feel spot on.
