Parts for your 2017 Toyota Crown-Coil springs

2017 Toyota Crown coil springs — what they do and how to look after them

Yes, coil springs are very much relevant on the 2017 Toyota Crown. Toyota’s technical references for the 210-series Crown (service manual/New Car Features and the Toyota Electronic Parts Catalogue) specify a coil-sprung suspension: a double-wishbone front and a multi-link rear, both using steel coil springs, with Adaptive Variable Suspension (AVS) dampers on some grades. Air suspension is generally associated with select Majesta variants, not the mainstream Athlete and Royal models sold in 2017.

On a 2017 Crown, the coil springs carry the weight of the car, set ride height, and let the dampers (shocks) focus on controlling motion. That pairing keeps the big Toyota riding comfortably over corrugations while keeping tyres planted in corners. Over time, springs can sag, crack, or corrode, especially if the car lives near the coast or sees rough roads.

When it comes to servicing, there’s no fixed kilometre-based replacement interval for coil springs. Instead, they’re replaced on condition. A Crown that’s sitting lower on one corner, bottoms out over speed humps, feels floaty, or shows uneven tyre wear could be hinting at tired or broken coils. Any obvious rust flaking, chipped powder-coat, or a snapped pigtail end means it’s time to swap them out.

Best practice for this model includes:

• Replace springs in axle pairs to keep the ride level and handling balanced.
• Inspect and, if needed, renew spring seats/insulators, bump stops and top mounts while you’re there.
• Pair new coils with healthy dampers, AVS shocks should be checked for leaks and correct operation.
• Have the wheel alignment set after any suspension work to protect tyre life.

Coil springs are under serious load, so removal needs a proper spring compressor and the right procedure. Torque settings should be finalised at normal ride height to avoid bushing preload. A workshop that knows Crowns will also check sway bar links, control arm bushes and height measurements against the factory spec from Toyota’s service data.

Owners who prefer a slightly firmer or lower stance can choose quality aftermarket coils rated for the Crown’s weight and AVS compatibility. For day-to-day Aussie and Kiwi roads, fresh OEM-rate springs keep the refined ride the Crown is known for without upsetting its calm, quiet character.

Popular questions about 2017 Toyota Crown coil springs

How long do coil springs last on a 2017 Crown?
There’s no set lifespan in kilometres. Many Crowns go well past 150,000 km on original coils if not overloaded and kept away from harsh corrosion. Regular inspections during servicing are the key—replace when there’s sag, damage or corrosion, not just by the odometer.

Can coil springs be replaced on just one side?
It’s not recommended. Replacing in axle pairs keeps left–right ride height and handling consistent. A single new spring paired with an older one can cause the car to lean or feel twitchy under brakes and over bumps.

Will new coil springs improve the ride?
If the old coils are sagged or cracked, absolutely. New, correct-rate springs will restore proper ride height, suspension travel and stability. For the best result, ensure the dampers (especially AVS units) are in good nick and get a post-job alignment.
