2004 Mitsubishi Pajero Gas Struts — What They Do and When to Replace Them

Based on technical references—including the Mitsubishi Motors NM/NP Pajero (2000–2006) workshop manual for Body/Chassis sections and the Mitsubishi ASA/CAPS electronic parts catalogue—the 2004 Pajero is equipped with gas‑charged bonnet support struts and a gas‑damped rear door stay for the side‑hinged tailgate. Major aftermarket catalogues (e.g., Stabilus, Monroe) also list direct‑fit bonnet and rear door gas struts for this model, confirming they’re used and relevant.

On a 2004 Pajero, gas struts take the heavy lifting out of everyday use. Under the bonnet, a pair of nitrogen‑charged struts support and control the lift so the panel rises smoothly and stays put without a wobbly prop rod. At the back, the side‑hinged tailgate uses a damper/strut to control swing and hold the door in a stable position, especially handy on slopes or in a stiff breeze. It’s all about safer, easier access with fewer surprises.

Like any wear item, gas struts lose charge and damping over time. Heat, dust, and regular use can thin out seals and drop internal pressure. That’s why it’s smart to fold them into routine servicing—quick checks now save busted knuckles later.

• Bonnet or tailgate won’t stay up, or slowly sags.
• Lift feels heavy, needs two hands where it used to glide.
• Hissing, oil mist on the shaft, or visible seal weep.
• Jerky, uneven motion instead of smooth damping.
• Worse performance in cold mornings (pressure sensitivity).
• One side stronger than the other (vehicle leans the load).

Maintenance is straightforward. Keep shafts clean—wipe with a soft cloth, avoid silicone sprays or grease on the rod, and never nick the chrome. Don’t force a frozen strut, that damages seals. There’s no practical “re‑gassing” for most units, replacement is the go‑to fix when performance drops.

• Replace in pairs on the bonnet to keep lift even.
• Support the panel with a prop or mate—safety first.
• Match length, end fittings, and rated force to the Pajero’s spec.
• Follow workshop manual guidance for attachment points and torque.

Good quality OEM‑equivalent struts restore that new‑car feel and help protect hinges and latches. For most owners, a quick inspection every service or 12 months is plenty, swap them out at the first sign of droop or jerky action and enjoy hassle‑free openings for years.

Popular questions

How long do gas struts last on a 2004 Pajero?
Service life varies with climate and usage, but many see 5–10 years. Coastal air, dust, frequent heavy use, and big temperature swings can shorten that. If the bonnet or tailgate starts to sag or feels heavy, don’t wait—swap them before they become a safety issue.

Can Pajero gas struts be re‑gassed, or should they be replaced?
For most Pajero applications, replacement is the practical solution. Re‑gassing requires specialised ports and equipment and often isn’t cost‑effective. Fresh, correctly rated struts are affordable and restore proper lift and damping immediately.

Are bonnet and tailgate struts the same on this model?
No. Bonnet struts and the tailgate door damper have different lengths, end fittings, and force ratings. Always order to position and model year, and check fittings match the original hardware before installation.
