Parts for your 2008 Mazda Premacy-Coil springs

2008 Mazda Premacy coil springs — what they do and when to replace them

Coil springs are absolutely used on the 2008 Mazda Premacy (also known as the CR-series Mazda5). Technical sources including the Mazda CR chassis/suspension workshop manual, Autodata suspension specifications, and major parts catalogues from KYB/Monroe list the Premacy with MacPherson struts and coil springs up front and a multi-link rear with separate coil springs and shocks. That means coil springs are directly relevant to this model, front and rear.

On this Premacy, the coil springs carry the vehicle’s weight, set the ride height, and let the suspension move through bumps without smashing through to the stops. Paired with the struts/shocks, they keep tyres planted and the body nice and controlled in corners, braking, and over corrugations. If the springs are tired, cracked, or sagged, the car can sit low on one corner, feel floaty, crashy, or bang over speed humps, and chew out tyres faster than it should.

As part of regular servicing, it’s smart to have the springs and seats inspected every 20,000–30,000 km or annually if the car sees heavy loads, a tow bar, or rough roads. A tech should look for broken coils (often the bottom turn), rust pitting, chipped coating, collapsed or perished rubber isolators, and uneven ride height. Any break means immediate replacement. If one spring is gone, the best practice is to replace springs in axle pairs to keep balance and ride height even, then do a wheel alignment.

When choosing replacements, match the build code/engine and seating spec, as the Premacy ran different spring rates for variants (petrol vs diesel in some markets, seven-seat trim, etc.). Going for heavy-duty or towing springs can help if the car regularly carries a full crew or cargo, but expect a firmer feel. Always reuse or replace the rubber isolators and check the shocks at the same time—weak dampers will kill new springs early and make the ride choppy.

After fitting, expect the ride height to settle a touch over the first few hundred kilometres. Listen for new knocks—often that’s a missed isolator or a spring not correctly seated in its perch. Keep the underbody rinsed if driving near the coast to slow corrosion on the coils and hardware.

• Inspect springs and seats during each major service
• Replace in pairs, align afterwards
• Match spring spec to variant and load needs
• Check shocks, mounts, and isolators at the same time

FAQs — 2008 Mazda Premacy coil springs

How can someone tell the coil springs on a 2008 Premacy need replacing?

Common signs include a noticeable sag on one corner, clunks over bumps, uneven tyre wear, or a harsh, crashy ride. A visual check often shows a broken bottom coil, rust flaking under the paint, or a spring that’s not seated correctly. Measuring ride height left-to-right on level ground is a quick at-home check.

Do coil springs need to be replaced in pairs on this model?

Yes—front pair or rear pair together. Pair replacement keeps the ride height and handling balanced and prevents a new spring from fighting an old, sagged mate. It’s also the ideal time to replace rubber isolators and book a wheel alignment.

Are there different coil springs for different Premacy variants?

Yes. Spring rates and free lengths can vary by engine, seating/trim level, and market. Using VIN or spring code ensures the correct rate and height. If the vehicle often carries extra weight, a heavy-duty option may be worthwhile, with a small trade-off in firmness.
