Parts for your 2003 Mitsubishi Pajero-Gas struts

2003 Mitsubishi Pajero gas struts

Based on technical references, gas struts are relevant and used on the 2003 Mitsubishi Pajero (NM/NP series). The Mitsubishi Pajero/Montero Service Manual for the V6/V7 platform (Body – Rear Door section) specifies a gas-charged rear door stay/damper, and the Mitsubishi ASA electronic parts catalogue lists a gas-filled “rear door stay” for these models. Industry catalogues from major lift-support makers also list gas springs for the Pajero’s rear swing door and, depending on trim/market, for the bonnet. So yes—this Pajero runs gas struts.

On this model, the gas strut on the side-hinged rear door helps control opening and holds the door steady, even with the spare wheel hanging off it. Where fitted, bonnet struts make lifting the bonnet easier and keep it up without wrestling with a prop rod. They’re charged with nitrogen and a light oil film, providing smooth, damped movement that feels solid and safe—ideal when loading the back or doing a quick check under the bonnet.

As part of regular servicing, it’s smart to check the Pajero’s gas struts. Typical lifespan is 5–8 years, but heat, cold, dust and road grime can shorten that. Telltale signs they’re tired include the rear door drifting shut on a slope, slow or jerky movement, a faint oil mist on the shaft or body, and poor performance on cold mornings. If the bonnet drops or the door won’t hold its position, it’s time to replace.

When replacing, match the correct force rating, extended/compressed lengths and end fittings to the vehicle. Replace bonnet struts as a pair so the lift is balanced, the rear swing door usually runs a single damper—replace that one unit with an equivalent-quality part. Always support the door/bonnet securely before popping the retaining clips, and never pry or twist the rod. Don’t grease the chrome shaft—just keep it clean, lubricants attract grit that can damage the seal.

• Inspect every service interval for oil weep, bent rods or loose mounts
• Listen for creaks or hisses and check operation on inclines
• Use quality replacements rated for the Pajero’s door weight and climate
• Dispose of old struts safely—pressurised units must not be punctured

Fresh gas struts make the Pajero feel newer, safer and easier to live with—no shoulder workout needed to hold the door while loading the esky.

Does a 2003 Pajero definitely have gas struts?

Yes—the rear swing door uses a gas-charged damper from factory. Bonnet support varies by market and trim, some have a prop rod, others have gas struts, and many owners retrofit bonnet struts for convenience.

How long do Pajero gas struts last, and what are the warning signs?

Expect roughly 5–8 years, but heavy use, dust and big temperature swings can shorten that. Watch for the door not staying open, slow or jerky action, oil residue on the strut, or the bonnet dropping. If performance drops noticeably in cold weather, they’re near the end.

Can a DIYer replace them at home?

Absolutely. Support the door or bonnet, pop the retaining clips with a small flat screwdriver, swap the strut, then click the new one on. Replace bonnet units in pairs. Avoid clamping the shaft and never open or heat a strut—it’s pressurised.
