Parts for your 2012 Mazda Premacy-Coil springs

2012 Mazda Premacy coil springs — purpose, care and when to replace

Coil springs are absolutely relevant on the 2012 Mazda Premacy (also known as Mazda5). Technical references including the 2012 Mazda5/Premacy Workshop Manual (Suspension section) and Mazda Global Service Support material specify a MacPherson strut front suspension with separate coil springs and a rear multi-link arrangement that also uses coil springs. These sources confirm the vehicle relies on coils at both ends for ride height and comfort.

On this Premacy, the coil springs do the heavy lifting: they carry the car’s weight, set ride height, and soak up bumps so the dampers (shocks/struts) can control rebound. Good coils keep the Mazda sharp in the corners, steady with a full load of kids and gear, and kind to tyres across the city and out on the open road.

When coils age, they can sag, crack or corrode—especially in coastal Aussie and Kiwi conditions. Typical tell-tales include:

• Uneven ride height or the vehicle sitting low on one corner
• Clunks over bumps, twanging noises when turning, or a crashy ride
• Excessive body roll, nose-diving under brakes, or bottoming out
• Abnormal tyre wear on one wheel, or poor headlight aim at night

As part of routine servicing on a 2012 Premacy, a technician should:

1. Inspect each coil for broken pigtails, chipped coating, rust flaking, and polished coils (coils touching).
2. Measure ride height against spec and compare side-to-side, any big mismatch points to spring fatigue.
3. Check top mounts, insulators, bump stops and dust boots at the same time—replace if cracked or perished.
4. Replace coil springs in axle pairs (both fronts or both rears) to keep balance and braking stable.
5. Torque fasteners with the vehicle at normal ride height so the bushes aren’t pre-loaded.
6. Book a wheel alignment after spring or strut work to protect tyres and steering feel.

For most Aussie/NZ driving, a visual check every 10,000–15,000 km or at each service is smart. If the Premacy tows, hauls regular loads, or lives near the beach, up the vigilance—surface rust can turn into a snapped coil at the bottom seat. OE or reputable aftermarket coils matched to the correct engine and trim level will restore ride height and comfort. If using a spring compressor, leave it to a pro, the stored energy is no joke.

Popular questions

What are the signs my 2012 Premacy’s coil springs are failing?
Look for a droopy corner, clunks over bumps, extra body roll, or scrubbing tyres. A broken coil often shows up as a sudden drop in ride height and a metallic rattle near the spring seat.

Do coil springs need to be replaced in pairs?
Yes—replace both fronts or both rears together. Pairing keeps ride height even and handling predictable, and it prevents the fresh coil from fighting an old, sagged one.

How often should the coil springs be checked?
Have them inspected at every service or at least every 10,000–15,000 km. If the vehicle carries heavy loads or lives in salty air, ask for a closer look twice a year.
