Parts for your 2002 Lexus Is-Strut mounts

2002 Lexus IS strut-mounts — are they used?

For the 2002 Lexus IS (IS200/IS300, XE10), factory suspension design uses double wishbones front and rear, not MacPherson struts. This layout is detailed in Lexus service literature, including the Lexus IS (XE10) New Car Features and the Repair Manual, which explain that the steering axis runs through the upper and lower ball joints, with the shock absorber and spring acting as non-structural components. Because there’s no MacPherson strut, there’s no conventional strut-mount with a steering bearing at the top.

That’s why “strut-mounts” aren’t relevant on a stock 2002 Lexus IS. Instead, the car uses shock absorber upper mounts/insulators (often called top hats or cushions). These are rubber-isolated mounts that locate and isolate the damper and spring, but they don’t rotate with steering and aren’t the same as a strut top bearing found on many front-wheel-drive cars.

If someone’s hunting for “strut-mounts” for this model, what they usually need are the front shock absorber upper insulators and the rear shock absorber upper mounts. These parts are documented in Toyota/Lexus EPC and the factory Repair Manual as shock absorber mounts/insulators rather than strut tops, which aligns with the double-wishbone design.

Servicing tips for owners and workshops:

• Listen for clunks over speed humps or sharp bumps, perished upper insulators can allow metal-to-metal contact.
• Inspect the rubber for cracks, collapse, or separation, and check spring seats, dust boots and bump stops at the same time.
• Replace mounts in axle pairs to keep ride height and noise characteristics even left-to-right.
• Support the control arm when removing the damper/spring to avoid stressing ball joints and bushes.
• A wheel alignment check is wise after suspension work, even though removing the damper on a double wishbone usually doesn’t alter camber/caster much.

Note: Aftermarket coilover kits may include their own “strut tops” or camber plates, that’s specific to the kit and not the factory IS200/IS300 setup. Sticking with OE-style shock mounts/insulators will keep the car riding quietly and compliantly, just as Lexus intended for Aussie and Kiwi roads.

Does a 2002 Lexus IS have strut-mounts?

No. The 2002 IS200/IS300 uses double-wishbone suspension front and rear per Lexus New Car Features and Repair Manual documentation, so there are no MacPherson struts or strut-mounts with steering bearings. The car instead uses shock absorber upper mounts/insulators.

What should be ordered instead of strut-mounts?

Order the front shock absorber upper insulators (top mounts) and the rear shock absorber upper mounts/insulators, plus spring seats, dust boots and bump stops if they’re tired. These are the correct factory-fit parts for the XE10 chassis.

What symptoms point to worn mounts/insulators on an IS200/IS300?

Common signs include a dull clunk over potholes or speed humps, a slightly loose feel from the front end, or creaks when the suspension compresses. Visual checks often show cracked or squashed rubber. If noises persist, also inspect control arm bushes and ball joints, as these are frequent wear items on double-wishbone setups.
