Parts for your 2003 Toyota Altezza-Strut mounts

Are strut mounts used on the 2003 Toyota Altezza?

Short answer: no, the 2003 Toyota Altezza (XE10 platform) doesn’t use strut mounts in the usual MacPherson-strut sense. Technical sources including Toyota’s New Car Features for the XE10 platform, the Lexus IS/Altezza Repair Manual (Chassis – Suspension), and the Toyota Electronic Parts Catalogue show the Altezza running double-wishbone suspension front and rear, not MacPherson struts. Because the steering axis is carried by upper and lower control arms, there’s no rotating strut assembly and therefore no strut-top bearing plate, which is what most people mean by a “strut mount”.

Instead, the Altezza uses shock absorbers with upper insulators/bushes that fasten to the body. These upper insulators are sometimes listed online as “strut mounts”, but they don’t contain a steering bearing and don’t do the same job as a MacPherson strut top. If someone’s shopping for 2003toyotaaltezza strutmounts, what they actually need are damper top insulators (and possibly spring seats), or they’re chasing wear in control arm bushes and ball joints.

Why strut mounts aren’t used here comes down to geometry. In a MacPherson layout, the strut is the main locating member and it must rotate with the steering, so it needs a bearing-supported top mount. In the Altezza’s double-wishbone setup, the damper doesn’t steer, the arms manage wheel location and steering axis. That means no strut-top bearing is required.

What to service instead on an Altezza when chasing top-end knocks, vibration or vague steering:

• Damper upper insulators and spring seats (front and rear)
• Upper and lower control arm bushes and ball joints
• Sway bar links and bushes
• Top hat rubbers on aftermarket suspension
• Wheel alignment after any suspension work, to keep tyre wear even

Owners running aftermarket coilovers may see “top mounts” or camber plates (often with a pillow-ball). Those are part of the coilover kit, not OE strut mounts. They can develop play or noise over time and should be inspected, kept tight to the maker’s torque specs, and replaced if they develop slop.

For routine servicing, a mechanic will usually check the damper top insulators for cracking, the control arm bushes for splits, and the sway bar links for play. Any thuds over speed humps, clunks on lock, or steering shimmy at motorway speeds are good reasons to get the suspension looked at. Keeping these bits tidy preserves that planted Altezza feel and keeps tyres wearing nice and evenly across the tread.

FAQ: Does a 2003 Toyota Altezza have strut mounts?

No. The XE10 Altezza uses double-wishbone suspension, so it doesn’t need a strut-top bearing plate. It has damper upper insulators instead. Toyota’s New Car Features, the Lexus IS/Altezza Repair Manual (Suspension), and the Toyota EPC all outline this layout.

FAQ: What should be replaced if the top of the suspension is knocking?

Start with the damper upper insulators and spring seats, then check control arm bushes and ball joints, plus sway bar links. These are the usual wear points on an Altezza and commonly cause knocks, creaks or vague steering.

FAQ: I’ve got coilovers—do they use strut mounts?

Many coilovers come with their own top mounts or camber plates (often a pillow-ball). They’re not OE strut mounts, but they do act as the upper attachment. Inspect them regularly for play or noise and re-torque fasteners as per the coilover manufacturer’s guidance.
