Parts for your 2014 Nissan Navara-Gas struts

2014 Nissan Navara gas struts (bonnet)

Gas struts are relevant to the 2014 Nissan Navara (D40) because the bonnet uses twin gas-filled stays from factory to support and control lifting. This is documented in Nissan’s D40 Navara Service Manual under the Body/Exterior (Hood) section, which illustrates the bonnet gas stays and outlines inspection and removal/refit procedures. Application catalogues from major strut manufacturers (e.g., Stabilus and Monroe) also list dedicated bonnet gas struts for the D40 (2005–2015), confirming fitment on 2014 models. These are bonnet-only items, tailgate dampers on a Navara are aftermarket accessories, not OE.

On a 2014 Navara, the bonnet gas struts make life easier by taking the weight of the bonnet and holding it open safely. They smooth out the lift so there’s no shoulder strain, and they stop the bonnet from slamming shut if there’s a gust of wind. Inside each strut is pressurised gas and a small amount of oil that work together to give controlled movement and consistent hold.

As part of regular servicing, it’s smart to give the bonnet struts a quick once-over. Wipe the chrome shafts clean, check for any oil misting around the seals, and test hold by opening the bonnet and seeing if it stays up confidently—especially when it’s cold. If the bonnet feels heavy, drops, creaks, or needs a helping hand to rise, the struts are likely past their best.

When replacement time comes, it’s a straightforward job but do support the bonnet securely—never trust a weak strut. Replace in pairs so the lift and hold are even on both sides. Quality matters here, better-spec units keep their charge longer and cope with Aussie and Kiwi temperature swings. Fit them rod-end down as designed, make sure the ball sockets click home, and avoid grabbing the shiny shaft with pliers—nicked shafts kill seals.

A good rule is to inspect the struts at every service and expect a lifespan of 5–10 years depending on use, climate, and exposure. Keeping the shafts clean, avoiding lubricants on the seals, and not overloading the bonnet with accessories will help them last. If the Navara runs a canopy, remember those glass hatches often have their own gas struts that need the same care—but they’re separate to the bonnet struts.

Technical sources referenced: Nissan Navara D40 Series Service Manual (Body/Exterior – Hood/Bonnet section: gas stay description, inspection and R&,R), Stabilus Lift-O-Mat and Monroe Max-Lift application guides listing D40 bonnet gas struts for 2005–2015 production.

• Signs they’re failing: bonnet won’t stay up, slow or jerky lift, oil film on shaft, worse performance in cold weather.
• Service tip: inspect every service, replace in pairs, support the bonnet during any work.

Popular questions about 2014 Nissan Navara gas struts

Do 2014 Navara utes come with factory bonnet gas struts?
Yes. The D40 Navara (including 2014 models) is fitted with twin gas bonnet stays from factory. They’re designed to assist lifting and hold the bonnet securely without a prop rod. Tailgate dampers, if fitted, are aftermarket and separate to the bonnet struts.

How long do Navara bonnet struts usually last?
Typically 5–10 years in Australian and New Zealand conditions. Heat, dust, and frequent bonnet use can shorten that. If the bonnet starts to sag or needs a shove to open, it’s time to test and likely replace them in pairs.

Can just one strut be replaced, or should both be done?
It’s best practise to replace both. Pair replacement keeps lift and holding force balanced, preventing undue stress on hinges and the remaining old strut, and avoids a half-fixed feel where the bonnet still feels heavy on one side.
