Parts for your 2013 Toyota Avensis-Gas struts

2013 Toyota Avensis gas struts — what they do and when to sort them out

Technical documentation for the T27-series Avensis (Toyota Europe Repair Manual and Electronic Parts Catalogue for ZRT27#/ADT27#) shows the 2013 Avensis Wagon/estate uses gas struts on the back door/tailgate. The saloon’s boot uses torsion bars, and the bonnet on both body styles uses a manual prop rod. So gas struts are relevant for the 2013 Avensis Wagon tailgate, and for any owner replacing those lift supports.

On the 2013 Avensis Wagon, gas struts do the heavy lifting each time the tailgate’s opened. They counterbalance the door’s weight, control its speed, and hold it safely at full height. When they’re healthy, the tailgate lifts smoothly and stays put, even on a breezy Wellington wharf or a hot Perth afternoon. As the seals and internal nitrogen charge age, they lose force, which shows up as a tailgate that won’t stay up, rises slowly, or needs a shoulder nudge to get moving.

As part of routine servicing, it’s worth giving the tailgate struts a quick once-over:

• Look for oil misting around the shaft or end seals.
• Listen for creaks or binding and feel for any stiction on first movement.
• Check holding power — the door should stay fully open without creeping down.
• Inspect the ball studs and clips for corrosion or play.

Replacement is straightforward but safety-first: always support the tailgate with a prop or a mate before popping the clips. Swap struts in pairs to keep lift and damping even. Avoid gripping the polished shafts with pliers, any nick will ruin the seal and shorten life. Don’t lubricate the shafts — keep them clean and dry, wiping away dust with a soft cloth. If you often park nose-up on a steep driveway or use the tailgate as a shelter at the footy, expect earlier wear, temperature and usage patterns matter.

Quality OEM-equivalent struts restore smooth, predictable lift. After fitting, cycle the tailgate a few times to ensure the clips are seated and there’s no interference with trims or wiring. A healthy set of struts isn’t just convenient — it protects hinges, latches, and, most importantly, heads and fingers.

• How long do gas struts last on a 2013 Avensis?
• Should gas struts be replaced in pairs?
• Can weak gas struts be re-gassed?

How long do gas struts last on a 2013 Avensis?
In typical Aussie and Kiwi conditions, 5–10 years is common, but high heat, frequent use, and grit can bring that forward. If the tailgate won’t hold itself up or lifts sluggishly, they’re due.

Should gas struts be replaced in pairs?
Yes. Replacing both maintains balanced lift and prevents twisting of the tailgate. A single new strut paired with an old weak one will feel odd and can stress hinges.

Can weak gas struts be re-gassed?
Most automotive tailgate struts are sealed units. Re-gassing isn’t recommended, replacement with quality new struts is the reliable, cost-effective fix.
