2012 Nissan X‑Trail gas struts — what they do and when to replace them

Yes, gas struts are used on the 2012 Nissan X‑Trail (T31). Technical sources confirm factory‑fitted gas‑charged “Back Door Stay” units support the rear tailgate: the Nissan X‑TRAIL T31 Series Service Manual (2011–2013), Body/Back Door section, specifies gas struts for the tailgate, the Nissan FAST electronic parts catalogue lists Stay Assy–Back Door (e.g., P/N 90450‑JG00A/90450‑JG01A) for T31, and major technical catalogues from Stabilus Lift‑O‑Mat and Monroe Max‑Lift cross‑reference tailgate gas springs for 2007–2013 X‑TRAIL models. The bonnet on this model uses a support rod (as shown in the Service Manual’s Hood section), not gas struts from factory.

On a 2012 X‑Trail, the tailgate gas struts take the weight of the rear hatch, help it lift smoothly, and hold it safely open while loading gear. They’re nitrogen‑charged dampers, so they add lift assist and control the last bit of travel so the hatch doesn’t slam. Over time—especially after a decade of daily use, coastal air, or winter cold—they can lose pressure and feel weak.

Servicing is straightforward. During routine services, it’s smart to check the struts for smooth operation, any oil misting around the rod seal, or a hatch that won’t stay up on a chilly morning. Keep the chrome rods clean, don’t lubricate them with grease or silicone as that can damage the seals. If replacement’s needed, go for quality, vehicle‑specific units and swap them in pairs to keep opening force even. Support the tailgate securely (a mate or a prop) before releasing the ball‑sockets, then clip the new ones on—usually a quick job with no special tools.

Typical lifespan varies with use, but after 10‑plus years many originals are due. Fresh struts make day‑to‑day use easier, safer, and reduce strain on hinges and the latch.

• Signs it’s time to replace:
  • Tailgate sags or drops, especially in cold weather
  • Needs a big shove to start lifting or won’t reach full height
  • Visible oil film on the strut body or rod
  • Jerky movement, binding, or clicking at full extension
  • One side looks bent or the tailgate opens unevenly

Note: The X‑Trail’s bonnet isn’t factory‑fitted with gas struts—aftermarket kits exist, but the OEM setup uses a prop rod.

FAQs

How long do the X‑Trail tailgate gas struts usually last?
Many last 6–10 years, but climate and use matter. If the hatch sags in winter or won’t stay up, they’re ready for replacement even if they look fine.

Can the original struts be re‑gassed, or should they be replaced?
Most OEM automotive lift supports are crimped and not designed for re‑gassing. Replacement with quality new struts is the reliable, cost‑effective fix.

Does the 2012 X‑Trail have gas struts on the bonnet?
No, the bonnet uses a prop rod from factory. Gas‑strut bonnet kits are aftermarket additions if desired.
