Parts for your 2001 Toyota Altezza-Strut mounts

2001 Toyota Altezza strut-mounts — are they used?

Short answer: no, a traditional “strut mount” isn’t used on the 2001 Toyota Altezza (XE10). Technical documentation including the Toyota/Lexus Repair Manual for the XE10 chassis (Suspension section), the New Car Features (NCF) manual for IS200/IS300/Altezza, and Toyota’s EPC listings for SXE10/GXE10 all describe the Altezza as running double wishbone suspension front and rear. That means the shock-and-spring unit does not act as a structural steering strut, and there’s no rotating strut top bearing like you’d find in a MacPherson-strut setup.

On a MacPherson-strut car, the “strut mount” (often with an integrated bearing) carries vehicle weight, damper loads and steering rotation at the top of the strut. The Altezza’s double wishbone design separates those jobs. Steering loads and geometry are handled by the upper and lower control arms and their ball joints, while the damper and coil spring simply control vertical movement and are anchored to the body through a non-rotating upper insulator/support. So while some aftermarket catalogues loosely call that insulator a “strut top”, it isn’t a true strut mount and doesn’t contain a steering bearing.

Why Toyota went this way comes down to dynamics and packaging. The double wishbone layout gives better camber control through the stroke, sharper turn-in, and a planted feel that the Altezza/IS200 is known for. It also means fewer steering loads go through the damper tower, reducing the need for a bearing-type mount up top.

If there’s a knock or squeak from the top of the front or rear suspension on an Altezza, the usual suspects aren’t strut mounts but related components:

• Upper shock insulators/supports and their bushes
• Bump stops and dust boots
• Upper/lower control arm bushes and ball joints
• Sway bar links and bushes

During servicing, it’s worth checking those insulators for perishing or crush, making sure the top nut torque is to spec, and inspecting control arm bushes and ball joints for play. If the car’s on coilovers, note that some coilover kits include a pillow-ball “top hat”, that’s still not a factory-style strut mount, but a performance-centric upper mount used by the coilover assembly.

FAQs

Does a 2001 Toyota Altezza have strut mounts?
No. The Altezza uses double wishbone suspension front and rear, so there’s no steering-bearing strut mount. It uses an upper shock insulator/support instead.

What should be replaced if there’s a clunk at the top of the suspension?
Start with the upper shock insulator, bump stop and dust boot, then check control arm bushes, ball joints and sway bar links. These are the common wear points on an XE10.

I’m fitting coilovers — do I need strut mounts?
Coilovers for the Altezza typically come with their own top mounts (often pillow-ball). They replace the factory insulator but still aren’t “strut mounts” in the MacPherson sense.
