Parts for your 2001 Daihatsu Gran move-Gas struts

2001 Daihatsu Gran Move gas struts — what they do and when to replace them

Per the Daihatsu factory service manual (Body – Rear Door section) and the Daihatsu electronic parts catalogue for the G3-series Gran Move/Pyzar, this model uses gas-filled lift supports (gas struts) on the rear tailgate. The bonnet is held up by a manual prop rod, not gas struts. So yes, gas struts are relevant on the 2001 Daihatsu Gran Move — specifically for the tailgate.

On a Gran Move, the tailgate gas struts make everyday life easier by taking the weight of the rear door and controlling its movement. They help lift the tailgate smoothly and hold it open at full height so loading the weekly shop or the pram isn’t a wrestling match. Over time, the internal nitrogen charge and oil can degrade. You’ll notice the hatch won’t stay up, drops in colder weather, opens sluggishly, or leaves a light mist of oil on the shaft — all classic signs the struts are on the way out.

Replacement is straightforward and a tidy little upgrade to safety and convenience. Most owners replace struts in pairs to keep lift and balance even. A mechanic or a switched-on DIYer can do the job in about 20–40 minutes with basic hand tools, but the tailgate must be supported firmly during the swap — think a helper, a prop, or a purpose-made support. Avoid gripping the polished rod with pliers, don’t grease the shaft (it attracts grit and chews the seals), and make sure ball-stud mounts are snug and aligned so the strut isn’t twisted.

It’s smart to check tailgate operation at each service: does it lift cleanly, hold open for a few minutes, and close without a thud? A quick wipe of the strut shafts with a clean, dry cloth keeps dust at bay. If replacement’s due, look for units matched to the Gran Move’s tailgate weight and length, OE-style or quality aftermarket struts both do the trick. “Re-gassing” isn’t usually recommended — new struts are the reliable fix. With fresh gas struts fitted, the Gran Move’s hatch feels factory-fresh again, and there’s less risk of a surprise head knock.

• Symptoms to watch: hatch won’t stay up, slow rise, jerky motion, oil film on the rod, worse in cold weather.
• Best practice: replace in pairs, support the tailgate, and dispose of old pressurised struts responsibly.

Popular questions

How long do Gran Move tailgate gas struts usually last?
In typical Aussie and Kiwi conditions, expect around 5–10 years, depending on use, heat, and dust exposure. If the hatch starts sagging or won’t hold in winter, they’re due.

Can the original struts be re-gassed?
Generally, no. Most automotive gas struts are sealed-for-life. Re-gassing isn’t consistent or economical compared with fitting quality new struts designed for the Gran Move.

Does the 2001 Gran Move have gas struts on the bonnet?
No. The bonnet uses a prop rod. Only the rear tailgate is supported by gas struts from factory on this model.
