Parts for your 2007 Nissan Pathfinder-Gas struts

2007 Nissan Pathfinder gas struts

Based on technical references — notably the Nissan Pathfinder R51 Factory Service Manual (FSM) for Body (BL/DLK) and Glass & Window (GW) sections, which specify “gas stay” for the back door and the lift-up back door glass, and the Hood section describing a bonnet support rod — gas struts are indeed fitted to the 2007 Nissan Pathfinder’s rear tailgate and, where equipped, the separate lift-up rear glass. The bonnet uses a prop rod rather than struts. Nissan’s EPC/FAST parts catalogue also lists the “Stay Assy – Back Door” for the R51 series, reinforcing that gas struts are relevant to this model year.

On a 2007 Pathfinder, tailgate gas struts do the heavy lifting so the rear hatch rises smoothly and stays put overhead. They’re pressurised with nitrogen and a small amount of oil to control movement, which means they work quietly and reliably when they’re in good nick. Over time, seals wear and pressure drops, especially with plenty of stop–start school runs, beach trips, and seasonal temperature swings across Aus and NZ.

As part of regular servicing, it’s smart to give the tailgate a quick health check. If it’s slow to rise, won’t hold its own weight, drops unexpectedly, or needs a helping hand in cooler weather, the struts are on the way out. Any oily film on the shaft is another tell-tale sign.

Replacement is a straightforward job for a tech and usually done in pairs to keep the lift balanced. Using the OE-spec force rating stamped on the strut body avoids a hatch that slams or over-extends. With the hatch safely supported, the old clips are popped off, the ball sockets are eased away, and new struts click straight on. It’s a quick win that makes the car feel newer straight away — and far safer around family and gear.

• Check operation every service or 10,000–15,000 kilometres.
• Replace in pairs and match OE length and force rating.
• Lightly lube the ball studs, keep the chrome shafts clean and dry.
• Avoid pushing the hatch up by the strut body, use the handle.
• If fitted with lift-up rear glass, assess those smaller struts too.

Quality replacements restore smooth, controlled lift, reduce strain on hinges and latches, and save the odd bump on the head. Nice and simple.

Popular questions about 2007 Nissan Pathfinder gas struts

How do you know the tailgate gas struts need replacing?
Common signs include the hatch sagging or slowly dropping, hesitation when opening, needing a hand to start the lift, and worse performance in cold weather. A light oily residue on the strut shaft or around the seals also points to internal leakage.

If in doubt, have a tech load-test the struts. Don’t ignore a hatch that won’t stay up — it’s a safety hazard.

Should they be replaced in pairs?
Yes. Replacing both ensures even lift and correct holding force, preventing twist on hinges and glass. Always match the original length and the Newton force rating printed on the old struts or specified by Nissan.

How long do gas struts last?
Typically 5–10 years depending on climate, usage, and accessories. Extra rear weight (like mounted tools or added trim) and frequent short lifts can shorten lifespan. If the Pathfinder still runs its original struts from 2007, they’ve definitely earned a refresh.
