Parts for your 2016 Toyota Avensis-Gas struts

2016 Toyota Avensis gas struts — what they do and when to replace them

Technical sources confirm gas struts are relevant to the 2016 Toyota Avensis. Toyota’s Owner’s Manual for the T27 series (2015–2018 facelift), Toyota’s Electronic Parts Catalogue (EPC), and aftermarket application catalogues (e.g., Stabilus Lift-O-MAT and Monroe Max-Lift) all show the Touring Sports (wagon) uses a pair of gas-filled back-door stays for the tailgate. The bonnet is supported by a prop rod from factory, and the sedan’s boot typically uses torsion bars rather than gas struts.

On the Touring Sports, gas struts take the weight of the tailgate, help it glide up smoothly, and hold it open so there’s no surprise head knock. They’re nitrogen-charged dampers that balance lifting force and controlled motion, making day-to-day use feel light and predictable.

Like any sealed hydraulic component, gas struts wear over time. Common signs include the tailgate creeping down, rising sluggishly in cold weather, needing a helping hand to start moving, or light oil mist around the shaft. If one side is weak, replace both together to keep the lift even and avoid twisting the tailgate.

Servicing tips for Avensis owners:

• Inspect annually (or at every service): check lift speed, hold height, and look for oil film or bent ball studs.
• Keep the chrome shafts clean, don’t grease them. Wipe with a soft cloth only—grease attracts grit and damages seals.
• Temperature matters: struts feel weaker in winter. If the tailgate won’t stay up in mild weather, they’re due.
• Always support the tailgate before removal. A prop or a helper keeps things safe.
• Match the spec: correct end fittings and force rating (N) matter for smooth operation and latch alignment.

Replacement is straightforward: carefully pry the spring clips at each end with a small flat screwdriver, pop the old strut off the ball studs, then press the new one on until it snaps home. No need to open the clips fully. Fit left and right as a pair.

For sedan owners: your boot uses torsion bars, so there aren’t factory gas struts to service. The bonnet across the range uses a prop rod, aftermarket bonnet strut kits exist, but they’re not a Toyota factory item for 2016 Avensis.

Popular questions

Does the 2016 Avensis have gas struts on the bonnet?
From factory, no. The T27 Avensis uses a bonnet prop rod. Aftermarket bonnet strut kits are available if a hands-free lift is desired, but ensure brackets and clearances suit the Avensis to avoid fouling the guard or bonnet.

How long do the tailgate gas struts last on a Touring Sports?
Usage, temperature swings, and dust exposure all play a part, but many owners see 5–10 years. If the hatch won’t stay up or rises lazily even on a warm day, that’s your cue to replace both struts.

Can stronger struts be fitted to handle added weight (e.g., a rear hatch rack)?
It’s possible to increase force rating, but go carefully. Over-strong struts can stress hinges and make closing difficult. If accessories add weight, choose a modest step up and check that latching and panel alignment remain spot on.
