Parts for your 1991 Nissan Primera-Gas struts

1991 Nissan Primera gas struts – fitment, purpose and service tips

Technical references confirm the 1991 Nissan Primera (P10) hatch and wagon use gas-filled lift supports on the tailgate, while the sedan’s boot relies on torsion springs and the bonnet uses a prop rod rather than struts. Sources: Nissan Primera P10 Service Manual (Body – Doors/Back Door), Nissan FAST EPC (Group 801 “Stay Assy–Back Door” for P10), and aftermarket application catalogues such as Stabilus Lift-O-Mat and Monroe Max-Lift listing tailgate gas struts for 1990–1996 Primera.

Where fitted (hatch and wagon), gas struts do the heavy lifting of the back door, making it easy to open and keeping it safely held up. Over time, the internal nitrogen charge can fade and seals can wear, especially with age, cold mornings, or dust exposure. That’s when the tailgate starts drooping, opens sluggishly, or needs a shoulder nudge to get moving.

For owners of a 1991 Nissan Primera hatch or wagon, it’s smart to check the gas struts as part of routine servicing. A quick functional test during oil-and-filter time goes a long way: open the tailgate and see if it rises cleanly and holds at full height. Wipe the exposed shaft with a soft cloth and check for a light oil film, rust spots, or nicks. Don’t grease the shaft—lubricants attract grit and can damage seals.

• Common signs they’re due: tailgate won’t stay up, needs extra shove to open, feels weak in cooler weather, or there’s visible staining around the seal.
• Safety first: always support the tailgate with a prop or a helper before removing a strut.

Replacement is usually straightforward and best done in pairs to keep lift balanced. Most Primera tailgate struts use ball-socket ends with spring clips—ease the clip back, pop the strut off, and click the new one on. Check the end fittings and overall length/force match the originals. Inspect the ball studs for wear or corrosion and replace if sloppy. Dispose of old struts responsibly, they’re pressurised and shouldn’t be drilled or crushed at home.

For the P10 sedan, there are no boot gas struts to service—check the torsion rods and hinges instead. On all body styles, the bonnet uses a prop rod, so make sure the retaining clip is present and the pivot’s secure.

Popular questions about 1991 Nissan Primera gas struts

Do all 1991 Primera models have gas struts?
Hatch and wagon variants have gas struts on the tailgate. The sedan’s boot uses torsion springs, and the bonnet on all body styles uses a prop rod rather than gas struts.

How long do tailgate gas struts last, and when should they be replaced?
Typically 5–10 years, depending on climate and use. Replace when the tailgate won’t hold itself up, opens sluggishly, or shows oil staining around the shaft seal—ideally as a pair for even lift.

Can Primera gas struts be re-gassed?
Most OE-style units are sealed and not intended for re-gassing. Replacement with new, correctly rated struts is the reliable fix.
