Parts for your 2002 Toyota Ist-Strut mounts

2002 Toyota ist strut mounts — what they do and when to sort them

Based on Toyota’s technical literature for the NCP60-series ist (2002 launch) — including the Toyota Repair Manual (Suspension & Axle), Toyota New Car Features, and the Toyota Electronic Parts Catalogue — the 2002 Toyota ist uses a MacPherson strut front suspension with a dedicated strut top support/mount that includes a bearing. The rear is a torsion-beam axle with separate shock absorbers, so there are no rear strut mounts on this model. In short: front strut mounts are absolutely relevant and fitted, rear “strut mounts” are not.

On the front of a 2002 Toyota ist, the strut mount sits at the top of the MacPherson strut assembly, under the bonnet. Its job is three-fold: it carries vehicle load, it isolates vibration and harshness with a rubber insulator, and it lets the strut turn smoothly with a built-in bearing so the steering feels light and consistent. When healthy, it keeps the front end quiet, ride quality tidy, and alignment stable.

Because the mount is a wear item, the rubber and bearing gradually cop a hiding from age, heat, and road shocks. Telltales include a dull clunk or knock over speed humps, groans or “memory steer” after turning, heavier-than-usual steering at parking speeds, or feathered front tyres. A visual check under the bonnet can show perished rubber, cracked isolators, or a slightly “mushroomed” strut tower area if things have gone on too long.

• Best practice is to replace strut mounts when fitting new front struts, or at around 120,000–180,000 km if symptoms appear sooner.
• Always replace mounts in axle pairs and follow with a wheel alignment to keep tyre wear in check.
• Choose quality mounts with an integrated bearing, cheap units can squeak or bind early.

There’s no routine lubrication — the bearing is sealed — but they should be inspected at each service, WOF/safety check, or if front-end noises pop up. Ensure the top centre nut and the three tower nuts are torqued correctly, and look for any corrosion or distortion at the strut tower. DIYers will need a proper spring compressor, if not equipped, a trusted workshop is the go-to. Done right, fresh mounts restore steering feel, calm the cabin, and protect new struts from premature grief.

Popular questions

Do 2002 Toyota ist models have rear strut mounts?
They don’t. The rear uses a torsion-beam axle with separate shock absorbers, so there are shock mounts at the rear, not strut mounts. Only the front suspension uses MacPherson struts with dedicated strut top mounts.

What are the common signs a front strut mount is worn on a 2002 ist?
Owners often notice a clunk over bumps, a creak when turning the wheel, or a tendency for the steering not to self-centre cleanly. You might also see uneven front tyre wear. Under the bonnet, cracked rubber at the mount or rust marks around the tower can hint at movement.

Should strut mounts be replaced with the struts?
Yes, that’s the smart move. The labour overlaps, and new struts paired with tired mounts can squeak, bind, or knock. Replacing mounts in pairs with quality parts and then doing a wheel alignment gives the best result for ride, steering feel, and tyre life.
