Parts for your 2018 Toyota Crown-Suspension bushes

2018 Toyota Crown suspension bushes: what they do and when to replace them

Suspension bushes are absolutely used on the 2018 Toyota Crown (S220 series). Toyota’s New Car Features manual for the S220 Crown, the Toyota Electronic Parts Catalogue, and Toyota’s TNGA platform technical materials describe multi-link suspension front and rear, with multiple rubber bushes at each control arm, the subframe mounts, and the stabiliser bar. So, yes—suspension bushes are relevant, and they’re central to how the Crown rides and handles.

On this model, the bushes sit where arms and bars meet the chassis or knuckles. Their job is to cushion vibration, keep alignment steady, and let the suspension move in a controlled way under braking, cornering and acceleration. Good bushes mean a quiet cabin, crisp steering feel, and even tyre wear—exactly the refined, planted character Crown owners expect.

Because bushes are made of rubber (some late-model units are fluid-filled for extra isolation), they age with heat, time and kilometres. Aussie and Kiwi roads, temperature swings, and the odd gravel detour can speed that up. Telltale signs include clunks over bumps, wandering or vague steering, shimmy under braking, and feathered or uneven tyres. Visible cracking, perishing, or oil-soaked rubber (from an engine or shock leak) means it’s time for attention.

Best practice is to inspect bushes at every service interval and during WOF/RWC checks. Many owners see replacements anywhere from 80,000 to 150,000 km, but time-based ageing (6–10 years) matters just as much. When replacing, go for quality OEM or reputable aftermarket parts. Note that some bushes are supplied only as part of complete arm assemblies on later Crowns—something your parts supplier can confirm via the EPC. After any control-arm or subframe bush work, a four-wheel alignment is a must.

• Replace bushes in axle pairs to keep handling balanced.
• Torque fasteners at normal ride height to avoid preloading the rubber.
• Use the correct press tools and observe bush orientation marks.
• Avoid petroleum-based lubricants on rubber, if using polyurethane, apply the supplied grease and expect a firmer ride with a touch more road feel and noise.

Look after the bushes and the Crown will keep that smooth, confident feel it’s known for—no creaks, no tramlining, just tidy, predictable behaviour on Aussie and NZ tarmac.

How long do suspension bushes last on a 2018 Toyota Crown?

Many owners see 80,000–150,000 km from factory bushes, but climate, roads and driving style matter. Even with low kilometres, rubber can age out in 6–10 years. Regular inspections during services or WOF/RWC checks will catch wear before it affects tyres or braking stability.

Do I need a wheel alignment after replacing bushes?

Yes. Any change to control arms or subframe bushes can shift camber, caster and toe. A proper four-wheel alignment after installation protects tyres and restores the Crown’s precise steering feel.

Are polyurethane bushes a good idea for this model?

They can sharpen response and last longer, but typically add a bit more noise and firmness. For a luxury-focused Crown, most owners prefer quality rubber or fluid-filled OEM parts, enthusiasts may choose poly for a sportier feel. Check local WOF/RWC expectations and discuss with a trusted technician.
