Parts for your 2010 Toyota Avensis-Gas struts

2010 Toyota Avensis gas struts — what they do and when to replace them

Yes, gas struts are used on the 2010 Toyota Avensis — specifically on the rear hatch of the Liftback and the Tourer (estate). The bonnet on this model uses a support rod, and the Sedan’s boot is sprung with torsion bars rather than gas struts. This setup is confirmed across Toyota’s T27 series technical literature: the Owner’s Manual specifies a bonnet support rod, the Toyota Electronic Parts Catalogue lists gas “back door stays” for the Liftback and Tourer, and common OEM supplier catalogues (such as Stabilus and Monroe) show gas-filled tailgate struts for 2009–2011 Avensis Liftback/Estate variants.

On the Avensis Liftback and Tourer, the gas struts are there to take the weight of the tailgate, letting it lift smoothly and stay put without slamming down. They’re sealed, nitrogen-charged dampers that balance lift assistance with controlled movement, so the hatch opens with a light push and holds position even in a breeze. Over time, seals wear and charge pressure drops, which is why a tailgate that once felt featherlight can start to feel heavy or sag unexpectedly.

As part of routine servicing, it’s worth giving the struts a quick once-over. Keep the shiny piston rods clean, wipe off grime with a soft cloth and avoid petroleum-based cleaners. If the hatch starts dropping, won’t stay up on a slope, needs a big shove to open, or moves jerkily, the struts are likely due. Cold mornings in Aus/NZ can make weak struts feel worse, so if they’re marginal in winter, they’re on the way out.

Replacement is straightforward for most home mechanics. Always support the tailgate securely (a helper or prop is essential), then flick the retaining clip at each end of the strut, pop it off the ball stud, and swap in the new unit. Fit in pairs to keep lift and damping even, and match the exact length and force rating to your VIN or OE specification — different body styles and option packs can use different struts. Lightly lubricate the ball joints with a silicone-safe product, keep oil and grease off the piston rod. Tighten any hardware to the workshop manual’s spec and check operation a few times to bed the joints in.

There’s no fixed replacement interval — quality struts often last many years — but once they lose holding power or start weeping oil, replacement is the smart, safe move.

• Common symptoms: hatch won’t hold up, slow or jerky lift, visible oil mist on the rod.
• Good practice: replace in pairs, verify fitment by VIN, and recheck after the first week.

Popular questions about 2010 Toyota Avensis gas struts

Which 2010 Avensis models actually have gas struts?
Liftback and Tourer (estate) models use gas struts on the rear hatch. The bonnet uses a manual support rod, and the Sedan’s boot uses torsion bars, so there are no gas struts on those areas.

How can someone tell the struts need replacing?
If the hatch won’t stay up, drops in a breeze, opens sluggishly, or shows oil residue on the piston rod, the struts are tired. Cold weather making it worse is another giveaway. If in doubt, replace them as a pair.

Can they be replaced at home?
Yes, provided the tailgate is safely supported. Pry the retaining clips, pop off the old struts, and clip the new ones onto the ball studs. Match the correct length and force to the vehicle’s VIN and double-check operation after fitting.
