Parts for your 2012 Toyota Corolla-Gas struts

2012 Toyota Corolla gas struts — what’s fitted and how to look after them

Based on Toyota’s service literature and parts catalogues for the E150/E160 Corolla series, gas struts are fitted to the rear hatch (back door) on 2012 Corolla hatchbacks sold in Australia and New Zealand. The Toyota Electronic Parts Catalogue lists the “Stay Assembly, Back Door” for ZRE152/153 (and later ZRE182/183) hatch models, while the bonnet uses a manual prop rod, and the sedan’s boot lid uses torsion bars rather than gas struts. Aftermarket fitment guides from major strut manufacturers also show gas-charged lift supports for the 2007–2013 Corolla hatch tailgate. So, gas struts are relevant for the hatch’s tailgate, but not for the sedan boot or bonnet.

On the 2012 Corolla hatch, the gas struts do the heavy lifting for the tailgate. They use compressed nitrogen and oil-damped pistons to counterweight the door, making it smooth to open and steady to hold up, even in a stiff Wellington southerly or a hot Perth summer. When healthy, they help prevent sudden drops and keep the tailgate parked at a safe height.

Typical signs they’re on the way out include:

• Tailgate dropping or sagging, especially in cold weather
• Needing a big shove to open, or slowing/stopping halfway
• Visible oil film or wetness on the strut shaft
• Hissing, binding, or uneven movement

They’re sealed units, so there’s no topping up gas or rebuilding at service time. Instead, keep the strut shafts clean and dry, don’t spray silicone or grease on the shafts (that can damage the seals), and check them during routine servicing. Most last 5–10 years depending on climate and use.

Replacement is straightforward and usually DIY-friendly:

1. Support the tailgate securely with a prop or helper.
2. Pop the clip(s) at each ball joint with a small flat screwdriver and slide the old strut off.
3. Install the new strut in the same orientation (gas force rating in N is printed on the body) and click onto the ball studs.
4. Replace in pairs to maintain balanced lift and hold.

During a scheduled service on a 2012 Corolla hatch, a quick functional check—open the tailgate fully and observe holding force and smooth travel—is usually enough. If there’s any doubt, measure opening effort or compare against the specified force on quality aftermarket or genuine replacements and renew both sides together. Owners of the 2012 Corolla sedan can skip tailgate struts altogether, its boot uses torsion springs, and the bonnet across both body styles relies on a prop rod.

Popular questions about 2012 Toyota Corolla gas struts

Which 2012 Corolla models actually have gas struts?
Hatchback models (ZRE152/153 and late-2012 ZRE182/183) use gas struts on the rear tailgate. The sedan’s boot lid uses torsion bars, and the bonnet on both body styles uses a manual prop rod, not gas struts.

How long do the tailgate gas struts usually last?
Typically 5–10 years, depending on climate and how often the tailgate’s used. Cold weather and constant opening/closing can shorten life. If the hatch won’t stay up or needs a push to open, it’s time for a new pair.

Can bonnet gas struts be retrofitted to a 2012 Corolla?
Yes, there are aftermarket bonnet strut kits for some Corolla variants, but Toyota didn’t fit them from factory on 2012 models. Choose a kit designed for the exact chassis and follow the supplied brackets and torque specs.
