Parts for your 1997 Daihatsu Gran move-Coil springs

1997 Daihatsu Gran Move coil springs — what they do and when to replace them

Based on technical sources including the Daihatsu factory workshop manual for the Pyzar/Gran Move platform (1996–2002), the Daihatsu Electronic Parts Catalogue (EPC), and aftermarket suspension catalogues (e.g., KYB and Monroe listings), the 1997 Daihatsu Gran Move is fitted with coil springs. The front uses MacPherson struts with coil springs, and the rear uses a torsion beam axle with separate coil springs and dampers. So yes—coil springs are absolutely relevant to this model.

On this tidy little MPV, the coil springs carry the vehicle’s weight, set ride height, and work with the shocks/struts to soak up bumps. They keep the tyres planted, help with steering stability, and make sure the Gran Move doesn’t bottom out over speed humps or when loaded for a weekend away. Over time, springs can sag, crack, or lose rate—especially if the car sees rough roads or heavy loads.

There’s no strict replacement interval, but regular inspections during servicing are a smart move. A technician should check for cracked coils, chipped paint exposing rust, uneven ride height, or the spring sitting off its seat. If one spring is shot, replace springs in axle pairs to keep the stance and handling even. Always match the correct spring rate and free length for the VIN/variant—catalogues list different rates depending on engine and equipment.

• Watch for tell-tales: knocking over bumps, a sagging corner, vague steering, or uneven tyre wear.
• Replace strut top mounts, bearings, insulators, and bump stops if they’re tired—cheap insurance while it’s apart.
• Use a proper spring compressor, compressed coils store serious energy. If unsure, leave it to a pro.
• Finish with a wheel alignment—ride height changes will alter camber and toe.

In Australian and New Zealand conditions, surface rust can creep up on older coils. Light surface rust is common, deep pitting or a cracked end coil is a fail for WoF/roadworthy. If the Gran Move is often loaded or tows, consider OE-equivalent heavy-duty options where listed. Keeping the springs healthy means better braking stability, consistent tyre contact, and a much nicer drive down bumpy backroads.

Does the 1997 Gran Move use coil springs front and rear?

Yes. Technical references for the Pyzar/Gran Move platform show a front MacPherson strut with coil springs and a rear torsion beam axle with separate coil springs. Both ends rely on coils for ride height and compliance.

How often should coil springs be replaced?

There’s no fixed kilometre interval. Inspect at every service or at least annually. Replace if you see cracks, significant rust pitting, sagging ride height, or if the vehicle bottoms out or leans. Always replace in pairs on the same axle.

Can you drive with a broken coil spring?

It’s unsafe and can damage tyres, shocks, and spring seats. Handling and braking can be unpredictable. Park it and organise a repair—your WoF/roadworthy will also fail with a broken spring.
