Parts for your 2018 Toyota Crown-Coil springs

2018 Toyota Crown coil springs — what they do and how to look after them

Coil springs are absolutely fitted to the 2018 Toyota Crown. Toyota’s official product information for the 2018 Crown release, together with the Toyota Electronic Parts Catalogue for late S210 and early S220 Crowns, lists dedicated front and rear coil springs, not air struts. The factory repair manual for these vehicles also includes procedures titled “Front Coil Spring Removal/Installation” and “Rear Coil Spring Removal/Installation,” confirming their use.

On the 2018 Crown, the coil springs support vehicle weight, set ride height, and help the dampers soak up bumps so the tyres stay planted. They work with the Crown’s independent suspension to balance comfort and control, keeping body roll in check while giving that easy-going, composed ride Crowns are known for. Different trims (hybrid vs petrol, RS vs G, etc.) use springs with different rates, so the exact feel depends on the spec — but they’re all coil springs.

Springs don’t have a set replacement interval, but they do wear. Look for a sagging stance, uneven corner heights, knocks over bumps, rust pitting, or a broken coil tail. Odd tyre wear and poor straight-line stability can also hint the springs or their seats are tired. If one fails or sags, replace in axle pairs to keep the car level and predictable, and book a wheel alignment straight after.

Service tips that pay off in Aus and NZ conditions:

• At each service, have a visual check for cracked paint, corrosion, or coils contacting each other. Clean off built-up road grime, especially if you’re coastal or drive on salted roads when heading to the snow.
• Inspect rubber isolators, spring seats, bump stops and top mounts — worn hardware can make a good spring feel bad.
• Avoid chronic overloading and big roof loads, both stress the springs and can lead to early sag.
• Pair new springs with fresh dampers if the shocks are aged, the combo restores ride height and control in one hit.

DIYers should use a quality spring compressor and follow torque specs from the Toyota repair literature — stored spring energy can bite. Parts selection is VIN‑sensitive on Crowns, so confirm the exact rate and height for your trim before ordering. For owners eyeing “lowering” springs, choose reputable kits matched to the Crown’s damper tuning and get a professional alignment to protect tyre life.

Popular questions about 2018 Toyota Crown coil springs

Does the 2018 Toyota Crown use coil springs or air suspension?
It uses conventional coil springs at both ends. Toyota’s product specs, EPC listings and the factory repair manual all refer to front and rear coil springs for the 2018 Crown. Air suspension was reserved for other Toyota luxury models in certain trims, not the standard 2018 Crown.

How long do the Crown’s coil springs last?
There’s no fixed lifespan. Many last well over 150,000 km, but coastal exposure, heavy loads, and rough roads can shorten that. Replace if there’s sagging, breakage, corrosion pitting, or if ride height is uneven. Always do springs in pairs on the same axle.

Can coil springs be replaced at home?
Yes, with the right tools and care. A proper spring compressor and adherence to the Toyota repair steps are essential. If in doubt, have a workshop handle it — they’ll also recheck torque and perform a post-job alignment to keep tyre wear tidy.
