Parts for your 1997 Daihatsu Gran move-Gas struts

1997 Daihatsu Gran Move — Gas Struts

Gas struts are relevant to the 1997 Daihatsu Gran Move. Technical references confirm the model uses gas-filled lift supports on the rear liftgate: the Daihatsu Electronic Parts Catalogue (M100/M101 Gran Move/Pyzar) lists a back door “stay (gas)”, the Daihatsu Body/Repair Manual describes removal and installation of the back door stay, and aftermarket catalogues such as Stabilus Lift-O-MAT and Monroe Max-Lift include application listings for the Gran Move/Pyzar rear hatch. The bonnet on this model typically uses a manual prop rod rather than gas struts.

On a Gran Move, the gas struts take the grunt work out of lifting the rear hatch and keep it safely open while loading. They’re nitrogen-charged dampers that provide smooth, controlled movement, making day-to-day use easier and safer. Over time, seals wear and internal pressure drops, especially with age, high mileage, or exposure to cold weather, so the hatch may feel heavy or start to sag.

For owners keeping a 1997 Daihatsu Gran Move in tidy nick, replacing tired gas struts is a quick win. Tell-tale signs it’s time include:

• The hatch won’t stay up, or drops suddenly.
• Slow lift in cooler temps, better when warm.
• Visible oil mist on the strut shaft or body.
• Stiction, creaks, or uneven lift on one side.

Replacement is straightforward and usually done in pairs to keep the lift balanced. Always support the hatch securely (use a helper or a prop) before popping the struts off their ball studs. Most units are retained by small spring clips—ease the clip back, lift the socket off, then reverse the process to install the new ones. If the sockets or ball studs are worn or corroded, replace those hardware bits too. After fitting, open and close the hatch a few times to ensure smooth, even operation.

Maintenance is minimal: keep the chrome shafts clean, avoid silicone sprays or petroleum grease on the shafts (they attract grit), and don’t use the hatch as a handle to pull yourself up—side loading can damage the struts. In Aussie and Kiwi conditions, expect a typical service life of 5–10 years, shorter if the vehicle lives outdoors or in colder climates. Sourcing by VIN or model code (Gran Move/Pyzar M100/M101) against reputable catalogues helps ensure the correct force rating and length.

Popular questions about 1997 Daihatsu Gran Move gas struts

Do all 1997 Gran Moves have gas struts on the rear hatch?
Yes. Technical references (Daihatsu EPC and body repair information) and major aftermarket catalogues list gas-charged stays for the Gran Move/Pyzar rear door. The bonnet typically uses a manual prop rod, so the gas struts are specific to the tailgate.

Can the original gas struts be re-gassed, or should they be replaced?
Most factory-style units are sealed and are best replaced when weak. Some local specialists in Australia and New Zealand can re-gas certain struts, but results vary and may not last as long as new replacements. For safety and consistency, matched new pairs are usually the better value.

How often should Gran Move gas struts be replaced?
There’s no fixed interval. Many last 5–10 years, but climate, usage, and storage matter. Replace when the hatch won’t stay up, lifts slowly (especially in cold), or shows oil film on the shaft. Always change them in pairs to keep the lift even.
