2017 Toyota Corolla gas struts: what’s fitted and how to look after them

Based on Toyota’s service literature and the Toyota Electronic Parts Catalogue (EPC) for the 11th‑generation Corolla (E170/E180), gas struts are fitted to the rear tailgate of the 2017 Corolla hatch (often coded ZRE/NRE 18x). The EPC lists “Back Door Stay Damper/Stay Assembly, Back Door” for the hatch, and the Repair Manual covers removal/installation and safety handling of the gas‑charged dampers. By contrast, the 2017 Corolla sedan (E170) uses torsion bars for the boot and a prop rod for the bonnet, there are no factory gas struts on those panels. So, gas struts are relevant for hatch owners, while sedan owners won’t find them on the boot or bonnet from the factory.

On the 2017 Corolla hatch, gas struts do the heavy lifting for the tailgate. They’re compact, gas‑charged dampers that counterbalance the weight of the hatch, so it opens smoothly, stays up without fuss, and closes without slamming. In everyday Aussie and Kiwi use—school runs, a quick Bunnings dash, or weekend sport—good struts save shoulders and prevent a droopy tailgate from bonking someone on the head.

As part of routine servicing, it’s worth checking tailgate operation. If the hatch doesn’t pop up cleanly, sags in a breeze, or needs a hand to stay open, the struts are likely tired. A light film of oil near the rod seal or any stick‑slip movement are other tell‑tales. Most sets last many years, but heat, dust, and frequent use can bring forward replacement.

Replacement on the Corolla hatch is straightforward and usually done in pairs to keep lift and damping balanced. Use a prop or a mate to hold the tailgate, flick the retaining clips at the ball ends, and swap the units. New struts typically arrive pre‑charged and ready to click on—no bleeding or special tools. While you’re there, inspect the ball studs for wear and make sure the hinges move freely.

Maintenance is simple: keep the chrome rods clean, don’t grease the rods (it attracts grit and can damage seals), and avoid using the tailgate as a perch. If the car’s parked outdoors, expect the struts to soften a bit sooner—hot summers and UV do their work. Choosing quality replacements that match the Corolla’s spec will restore that factory “lift and hold” feel and make daily use safer and easier.

• Common signs it’s time: hatch won’t stay up, slow lift in cold weather, oily residue at the seal, uneven or jerky motion.
• Service tip: always replace in pairs and support the hatch during the job.

Popular questions

Do all 2017 Corollas have gas struts?
Not all. The 2017 Corolla hatch uses gas struts on the tailgate. The 2017 Corolla sedan uses torsion bars for the boot and a prop rod for the bonnet, so there are no factory gas struts on those panels.

How long do hatch gas struts usually last on a 2017 Corolla?
Often 5–10 years, depending on climate and use. Lots of tailgate cycles, high heat, and exposure to the elements can shorten their life. If the hatch won’t stay up or lifts sluggishly—especially on cold mornings—it’s time to replace them.

Should both tailgate struts be replaced at the same time?
Yes. Swapping them as a pair keeps lift and damping even, which helps the hatch open smoothly and stay put. Replacing one can leave the tailgate unbalanced and put extra stress on the remaining older strut.
