Parts for your 2014 Holden Astra-Gas struts

2014 Holden Astra gas struts: what they do and when to replace them

Based on technical references for the Astra J platform (model year 2014), gas struts are indeed used on this vehicle. The Opel/GM Astra J Owner’s Manual for 2014 shows the tailgate supported by gas-filled struts, while the bonnet is supported by a manual prop rod. GM Service Information for Astra J includes “Liftgate Support Strut Replacement,” and Holden parts catalogues for the PJ/VXR body hardware list a liftgate gas spring, all confirming their fitment at the rear hatch/tailgate.

On a 2014 Holden Astra hatch or Sports Tourer, the tailgate gas struts take the heavy lifting so the hatch opens smoothly and stays safely up. They’re small, sealed cylinders charged with nitrogen gas and a light oil film, providing controlled lift and damping. Over years of use—especially with heat, cold, and dust—seals can tire and pressure drops, so struts lose their punch.

As part of routine servicing, it’s smart to check the Astra’s tailgate action. A healthy set should raise confidently and hold at full height without sagging. If the hatch falls in colder weather, needs a helping hand to lift, makes a hiss, or shows oil weep near the shaft, the struts are likely due. Because they work as a pair, replacing both together keeps lift and balance even.

• Safety first: support the tailgate with a prop or have a mate hold it up before removing any strut.
• Match the originals: use the correct length, end fittings, and force rating (usually printed on the old strut body or referenced by part number).
• Swap is straightforward: carefully flick back the spring clips at each end, pop the strut off the ball studs, then press the new one on. Keep the new strut oriented the same way as the original.
• Care tips: keep the shafts clean and dry, don’t lubricate the chrome rod with grease—it attracts grit and harms the seals. Avoid slamming the hatch.

Most Astra owners will see 5–8 years from tailgate struts, depending on climate and usage. Regular inspection, keeping the hatch drains clear, and replacing in pairs with quality parts will keep the tailgate light to lift and secure overhead. Note the bonnet on this model uses a prop rod, so bonnet gas struts aren’t part of the factory setup.

FAQs

Does a 2014 Holden Astra have gas struts on the bonnet?
Factory-fit bonnet support on the 2014 Astra is a manual prop rod, not gas struts. The gas struts are fitted to the tailgate. Some owners choose aftermarket bonnet strut kits, but these aren’t OE.

How long do tailgate gas struts last on a 2014 Astra?
Typically 5–8 years in Australasia, depending on heat, dust, and usage. Signs they’re fading include the hatch dropping, slow or uneven lift, and oil mist on the strut body. If one is weak, replace both.

Can Astra tailgate gas struts be replaced at home?
Yes, the job’s within DIY range. Support the hatch, pop off the retaining clips, and swap the struts one at a time, matching orientation and specifications. A helper is recommended for safety.
