1992 Mitsubishi Pajero Gas Struts: What They Do and When to Replace Them

Gas struts are indeed relevant to the 1992 Mitsubishi Pajero. The Mitsubishi Pajero/Montero V20-series factory workshop manual (Body section, Back Door) specifies a gas-charged damper/strut used on the side-hinged rear door to control opening and support the load, and Mitsubishi’s ASA/CAPS parts catalogue lists a gas spring for the back door on 1991–1999 Pajero models. Bonnet support on this generation is typically via a prop rod, not gas struts from factory.

On a ’92 Pajero, the rear door is hefty thanks to the side-swing design and the spare tyre mounted on it. The gas strut helps keep that door steady, slows it down so it doesn’t slam into the stop, and makes it easier to manage on a windy day or when parked on a slope. That little damper takes a hiding over time, and when the nitrogen charge fades, the door can feel heavy, swing too freely, or refuse to stay put.

As part of regular servicing, owners should give the back door strut a quick once-over. Typical signs it’s due for replacement include a door that won’t hold at the open position, a harsh swing with little damping, an oily film on the strut body, or a tell-tale hiss and weak action. Because the spare wheel adds weight, a tired strut is more than a nuisance—it’s a safety risk.

When replacing, match the strut to the Pajero’s year/series and tailgate configuration. Stick with known-quality units, over-pressurised “universal” struts can make the door fling open and stress hinges. Support the door securely before removal, minding fingers and paintwork. Don’t scratch or grease the chrome rod—just keep it clean, lubrication belongs on hinges and latches, not on the gas spring itself. After fitment, cycle the door a few times to settle the seals and check that the opening effort and hold are consistent. If working in colder southern climates, remember gas struts feel weaker in low temperatures—borderline units will show their age in winter.

There’s no strict interval for replacement—most last many years—but frequent off-road use, dust, and coastal air can shorten life. Re-gassing services exist, but if the rod is worn or the seals are tired, a new strut is the more reliable fix. Always dispose of old gas struts safely, they’re pressurised components.

• Common symptoms: door won’t stay open, fast uncontrolled swing, oily residue.
• Service tips: support the door, don’t grease the rod, choose correct-pressure replacements.
• Safety: avoid cheap over-strong units that can slam open and damage hinges.

Popular questions about 1992 Mitsubishi Pajero gas struts

Does a 1992 Pajero have bonnet gas struts from factory?
Most 1992 Pajeros use a bonnet prop rod from factory. Owners can fit aftermarket bonnet strut kits, but they should ensure bracketry clears snorkels, batteries, and accessories, and that the lift isn’t too aggressive for the bonnet skin.

How long do tailgate gas struts typically last?
Anything from 5–10 years is common, but usage and climate matter. Vehicles that live near the coast, tow often, or carry heavy rear-door accessories can see shorter service life. Replace when holding force and damping noticeably drop.

Can the original gas strut be re-gassed?
Some providers will re-gas, but if the internal seals or rod are worn, it won’t last. For an older Pajero, a quality replacement strut is usually the best-value, long-term solution.
