Parts for your 1998 Nissan Primera-Gas struts

1998 Nissan Primera gas struts: what’s fitted and what to service

Based on technical references including the Nissan P11 (1996–2002) factory service manual and Nissan Electronic Parts Catalogue (which list a gas‑filled liftgate “stay” for P11 hatch and wagon models), as well as application catalogues from Stabilus Lift-O-Mat and Monroe Max-Lift for the Primera 5‑door, the 1998 Nissan Primera uses gas struts on the rear liftgate of the hatch and wagon. The sedan’s boot typically uses torsion bars, and the bonnet is supported by a manual prop rod rather than gas struts. So, gas struts are relevant for hatch and wagon tailgates on this model.

On hatch and wagon versions of the 1998 Primera, gas struts do the heavy lifting on the tailgate. They’re small, gas‑charged cylinders that store energy and release it smoothly, helping the tailgate rise without a fight and stay put overhead. When they’re healthy, opening the rear is a one‑hand job and loading up is safer and easier, when they’re tired, the tailgate gets lazy, drops unexpectedly, or won’t hold in a breeze.

As part of routine servicing, it’s smart to give the struts a once‑over. Wipe the shafts clean, check the ball sockets and clips for play, and look for a light oil film or rust on the rods. If the tailgate no longer lifts confidently, sags as temperature drops, or needs a shoulder to keep it up, the gas has likely bled down and it’s time to swap them out.

• Tell‑tale signs: slow lift, short travel, a tailgate that bounces off the stops, oily residue on the rod, or a hatch that won’t stay up on cold mornings.
• Good practice: replace struts in pairs to keep lift balanced and avoid twisting the tailgate.
• Safety first: support the hatch with a prop or helper before removing clips, those last clips are all that’s holding it.

Choosing replacements is straightforward: match the body style (hatch or wagon), overall length, end fittings, and the force rating (Newtons). Reputable brands list the correct rating for P11 models, going too strong can make the hatch fire up and stress hinges, too weak and it won’t hold. Fitting is usually a simple clip‑off, clip‑on job with basic hand tools. Don’t grease the chrome shafts—lubricants attract grit and chew out seals. Instead, keep them clean and free of paint or overspray. In coastal Aussie and Kiwi conditions, expect service life of roughly 5–10 years, periodic checks during scheduled services will catch them before they catch you on the head.

FAQs

Which 1998 Primera models actually have gas struts?
Hatch and wagon (estate) variants use gas‑charged struts on the rear liftgate. The sedan’s boot relies on torsion bars, and the bonnet across the range uses a manual prop rod. If the car has a full rear liftgate, it’ll have struts.

How long do the tailgate struts last in AU/NZ conditions?
Typically 5–10 years, depending on usage and exposure. Coastal air and frequent heavy tailgate use shorten life. If the hatch won’t stay up in cold weather or feels lazy, plan on replacing them as a pair.

Can bonnet struts be added to a 1998 Primera?
Factory setup is a prop rod, but aftermarket bonnet‑strut kits do exist. Choose a kit made for the P11 so the force, brackets, and clearances are right, and follow the fitting instructions carefully to avoid panel misalignment.
