Parts for your 2005 Nissan Navara-Gas struts

2005 Nissan Navara gas struts — what’s fitted and how to look after them

Based on factory documentation and parts listings, gas struts are relevant to the 2005 Nissan Navara — specifically on D40-series utes released from 2005. The Nissan Electronic Parts Catalogue (FAST) and the D40 service manual’s Body/Hood sections note gas-charged bonnet supports. Earlier D22 models commonly sold alongside in 2005 typically use a manual prop rod for the bonnet, and the tailgate on both series is cable-supported (no gas struts) unless an aftermarket canopy or hard lid is fitted.

For D40 owners, the bonnet gas struts do the heavy lifting, making it easy and safe to open and hold the bonnet without a prop rod in the way. They’re nitrogen-charged dampers that provide smooth, controlled motion and keep the bonnet steady even in a breeze — handy when working on the ute at home or on the job.

As part of routine servicing on a 2005 Navara, it’s worth giving the bonnet struts a quick once-over. Struts are wear items, seals age, gas pressure drops, and performance tails off faster in cold weather or with lots of dusty site work. Common signs it’s time to replace them include:

• Bonnet won’t stay up or slowly sags
• Jerky movement or weak assist when lifting
• Oily film on the shaft or body
• Needing two hands or help to raise the bonnet

Replacement is straightforward and usually done in pairs to keep lift balanced. Always support the bonnet with a prop or a mate before popping the retaining clips. Match length, end fittings, and rated force to the vehicle spec, quality OE-style struts (e.g., from lift-support manufacturers listed for Navara D40 applications) restore the proper lift and hold.

There’s not much day-to-day maintenance beyond keeping the chrome shafts clean. Don’t grease them — oils can attack the seals. Wipe dirt away with a soft, dry cloth, avoid leaning on an open bonnet, and replace any bent ball studs or broken clips during fitment. Most sealed gas struts aren’t serviceable or “re-gassed” reliably, when they’re tired, swap them out.

If the ute is a D22 (prop rod) or you’re talking tailgates, gas struts aren’t factory — they’ll only be present if a canopy, lift-up window, or hard lid has been fitted.

Popular questions about 2005 Nissan Navara gas struts

Does a 2005 Navara have gas struts from factory?
On D40 models (launched 2005), yes — the bonnet uses gas struts. On D22 utes still sold in 2005, the bonnet uses a prop rod. The tailgate on both is cable-supported, so no gas struts unless there’s an accessory canopy or hard lid.

How long do Navara bonnet gas struts last?
Typically 5–10 years, depending on climate and use. If the bonnet won’t stay up, lifts sluggishly, or the struts show oil seepage, it’s time to replace — and it’s best to do them as a pair.

Can worn gas struts be re-gassed?
Most automotive bonnet struts are sealed and not designed for re-gassing. Replacement with the correct-length, correct-force units is the reliable fix, ensuring safe lift and proper hold.
