Parts for your 1999 Nissan Primera-Gas struts

1999 Nissan Primera gas struts

Technical sources including the Nissan Primera P11 Factory Service Manual (Body – Rear Door/Tailgate), the Nissan electronic parts catalogue, and the Haynes Service & Repair Manual for Primera models confirm that the 1999 Primera hatch and wagon use gas‑charged lift supports on the tailgate. The sedan’s boot commonly relies on torsion bars, and the bonnet uses a prop rod. So, for hatch and wagon owners, gas struts are absolutely relevant parts of regular servicing.

On the hatch or wagon, gas struts counterbalance the tailgate’s weight so it lifts smoothly, stays up without drama, and closes with predictable effort. They’re sealed, nitrogen‑charged dampers, and over time the pressure drops and a light oil mist can appear at the seals—especially after chilly NZ and Aussie winters. That’s when the gate starts sagging, needs an extra shove to lift, or thumps down when no one’s expecting it.

As part of routine servicing, a quick check every 10,000–15,000 km (or each service) is smart: look for weeping oil, pitted or rusty rods, bent housings, and loose ball studs. Wipe the chrome rods with a clean, dry cloth only—no silicone sprays or grease, which can swell the seals. If one strut is weak, replace them as a pair to keep lift and closing effort even. Always match OE extended/compressed lengths, end fittings, and force rating (in newtons), hatch and wagon specs differ, and many aftermarket catalogues list them separately.

When fitting, safely support the tailgate with a prop or a mate, pop the spring clips, and swap one side at a time. Inspect the ball studs and brackets, replace worn hardware, nip fasteners to spec, and consider a mild thread locker if recommended. After install, cycle the tailgate to confirm smooth travel and full hold at the top stop. Avoid slamming the tailgate and don’t use the struts as grab handles. If you’ve added a spoiler or often load the roof, consider correctly rated uprated struts rather than off‑spec “stiff” units. Dispose of old struts responsibly—don’t puncture them.

• Won’t stay up, drops faster in the cold
• Hissing sound or oil mist at the seal
• Pitted or scored rod surface
• Harder to open, or uneven lift left to right

Fresh gas struts make the Primera feel newer, safer, and far less hassle at the shops or school run.

Popular questions about 1999 Nissan Primera gas struts

How long do the gas struts usually last?
In local conditions they commonly last 5–10 years, depending on use, climate, and build quality. Cold weather accelerates pressure loss, so a tailgate that’s fine in summer might sag in winter. Regular inspection during servicing will catch them before they become a hazard.

Can just one gas strut be replaced?
It’s not recommended. Replacing in pairs keeps lift effort balanced, prevents twisting of the tailgate, and delivers full hold at the top. Mixing an old soft strut with a new firm one can stress hinges and brackets.

What size or force rating does the Primera need?
It depends on body style. Hatch and wagon tailgates use different lengths, fittings, and newton ratings. Match the OE part number or measure the old struts (centre‑to‑centre length and end types) and check a reputable parts catalogue for the correct force spec.
