Parts for your 2010 Mazda Premacy-Coil springs

2010 Mazda Premacy coil springs — fitment, purpose, and service tips

Coil springs are absolutely used on the 2010 Mazda Premacy (also known as Mazda5). Technical sources including the Mazda Global Service Manual for the CR series (Premacy/Mazda5, 2008–2010) specify a front MacPherson strut with a coil spring and a rear multi-link suspension with separate coil springs. Mazda’s Electronic Parts Catalogue for 2010 CR3W/CREW also lists front and rear coil springs by model/trim, and independent spec databases such as Autodata describe coil-spring independent suspension front and rear for this vehicle.

On this people mover, the coil springs carry the vehicle’s weight, hold ride height, and soak up bumps in tandem with the shocks/struts. They keep the Premacy stable when loaded with family, friends, and gear, helping tyres stay planted and steering feel consistent across Aussie and Kiwi roads. Healthy springs protect the dampers too, so comfort and control don’t go out the window over corrugations or speed humps.

As part of routine servicing, they should be visually inspected for cracks, broken ends, heavy rust pitting (common near the lower coils), and sagging. Tell-tales include a lopsided stance, clunks over bumps, steering that wanders, or uneven tyre wear. In coastal areas of Australia and New Zealand, salt exposure speeds up corrosion, so a periodic underbody rinse and a closer look at spring seats and insulators is smart. If a spring has failed or ride height has dropped, it’s best practice to replace in axle pairs to keep handling even. Always match the correct spring rate and colour-code for the exact CR variant and seating/option load rating.

Because springs store a heap of energy, removal needs a proper compressor and safety gear — it’s a technician’s job. While there, it pays to renew related parts like top mounts, bearings, dust boots and insulators, then finish with a wheel alignment. Keep loads within the Premacy’s limits, chronic overloading hammers springs and can trigger a WOF/RWC fail if one cracks. Owners running lowered setups should use quality, compliance-marked springs matched to suitable dampers and be aware that extreme drops can upset geometry, tyre life and legality. A quick check every 10,000–20,000 kilometres (or at each service) keeps surprises at bay and the people mover riding sweet as.

• Replace springs in pairs on the same axle
• Check mounts, seats, bump stops and shocks at the same time
• Book a wheel alignment after any spring or strut work

Popular questions about 2010 Mazda Premacy coil springs

What are the symptoms of a worn or broken coil spring?
A Premacy that sits low on one corner, clunks over bumps, or shows uneven tyre wear may have a spring issue. A clean break can also cause the steering to pull or feel nervous on coarse-chip roads.

Sometimes the first clue is a sharp change in ride height after a pothole hit. If there’s visible rust flaking or a snapped tail on the bottom coil, it’s time to replace.

Do coil springs need to be replaced in pairs?
Yes — on the same axle. Replacing just one can leave different ride heights and spring rates side to side, which affects braking stability and cornering feel. Pairing keeps the Premacy balanced and predictable.

How often should coil springs be inspected?
Have them checked at every service or at least every 10,000–20,000 km. If the vehicle tows, carries full loads often, or lives near the coast, increase the inspection frequency and keep the underbody clean to slow corrosion.
