Parts for your 2006 Toyota Crown-Coil springs

2006 Toyota Crown coil springs: what they do and how to look after them

Based on Toyota’s S180-series technical literature (Toyota Crown 2003–2008 Repair Manual), the Toyota Electronic Parts Catalogue for GRS18x models, and 2006 model brochures, coil springs are fitted front and rear on most 2006 Toyota Crown variants (Royal Saloon and Athlete). The Crown Majesta (UZS18x) commonly uses factory air suspension instead, so coil-springs aren’t relevant to Majesta trims unless they’ve been converted.

On 2006 Crown Royal and Athlete models, the coil springs are the workhorses of the suspension. Paired with the shocks/struts, they carry the vehicle’s weight, keep the ride height where it should be, and help the tyres stay planted over Aussie and Kiwi roads. The front runs a double wishbone setup with coils, while the rear uses a multi-link layout with coils — a neat balance of comfort and control for everyday use and keen driving alike.

They don’t have a fixed replacement interval, but they do wear. Owners should have the coil-springs checked at regular services (say every 10,000–15,000 km), or sooner if there’s a sagging corner, a knock over bumps, uneven tyre wear, or the car rides harsher than normal. Rust pitting (common near the lower pigtail and spring seats), chipped paint, or a broken coil are all reasons to replace. If the Crown sits nose-down or tail-low compared with factory ride height, the springs are likely tired.

• Replace springs in axle pairs to keep handling balanced.
• Inspect and, if needed, renew insulators, spring seats, bump stops and top mounts at the same time.
• Never heat or cut springs, use the correct spring compressor and safety gear.
• Tighten control arm and strut fasteners at normal ride height to avoid bush bind.
• Book a wheel alignment after spring work, it protects tyres and keeps the Crown tracking straight.

For owners chasing a sportier stance on an Athlete, quality lowering springs matched to appropriate dampers can sharpen things up, but check local regulations (WOF in NZ, state regs in AU) and don’t skimp on alignment. Sticking with OE-equivalent coils is ideal if the brief is comfort and quiet, especially for Royal Saloon duty.

If the vehicle is a Crown Majesta with factory air suspension, it won’t use coil-springs. Those systems rely on air struts and height sensors, servicing focuses on bag condition, compressor output and leak checks rather than coils.

Popular questions about 2006 Toyota Crown coil springs

Does a 2006 Toyota Crown use coil springs or air suspension?
Most 2006 Crown Royal Saloon and Athlete models use coil springs front and rear. The Crown Majesta variant typically has air suspension instead. If unsure, a quick look behind the front wheel will show a coil over the strut on coil-equipped cars, while Majesta air struts have rubber bellows.

What are the signs the Crown’s coil springs need replacing?
Common clues include a sagging corner, clunks over bumps, uneven ride height, accelerated tyre wear, and harsh or bouncy ride quality. Rust flaking or a snapped coil (often near the ends) also calls for immediate replacement.

Can the Crown be lowered with aftermarket coil springs?
Yes for Royal/Athlete models, but use quality springs matched to suitable dampers, and always get an alignment. Check local rules in AU/NZ regarding minimum ground clearance and certification to keep it legal and safe.
