Parts for your 2007 Nissan Serena-Gas struts

2007 Nissan Serena gas struts — what they do and when to replace them

Gas struts are absolutely relevant to the 2007 Nissan Serena (C25). Technical references confirm factory-fitted gas-filled stays on the rear tailgate: the Nissan Serena C25 factory service manual (Body — Back Door section) specifies a “back door stay (gas)”, and Nissan parts catalogues for the C25 list a “Stay Assy – Back Door (Gas)”. Major aftermarket catalogues (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) also include rear lift supports for the 2005–2010 Serena. The bonnet on most C25 variants uses a conventional prop rod, not gas struts.

On a Serena, gas struts do the heavy lifting on the big rear tailgate, taking the weight so the hatch opens smoothly and stays put overhead. They’re nitrogen-charged dampers that provide controlled assist on the way up and hold the door steady while loading prams, groceries, or tools. When healthy, they make the tailgate feel light and predictable, when tired, the door sags, opens slowly, or won’t stay up — not ideal on a wet day at the shops or the beach.

As part of regular servicing, it’s smart to give the tailgate struts a quick check. Look for:

• Reduced lift or needing an extra shove to open
• Door dropping or not holding at full height, especially in cold weather
• Oily residue on the strut shaft or body
• Clicking, binding, or uneven motion

Replacement is straightforward and usually done in pairs to keep lift and balance even. Support the tailgate safely with a prop or a mate holding it up. Most Serena struts use simple spring clips at the ball sockets — flick the clip back, pop the old strut off, seat the new one over the ball, and press to lock. Swap one side at a time to maintain alignment. Avoid twisting the rod, don’t nick the chrome shaft, and keep fingers clear of the hinge line. If the mounting balls are worn or rusty, replace them as well for a tight, rattle-free fit.

There’s no real “service” for gas struts — they’re sealed units — but a light wipe of the shaft with a clean cloth keeps grit off the seal, and a touch of anti-seize on the ball studs helps future removal. Expect lifespan to vary with climate and use, if the tailgate won’t stay up or the lift feels lazy, that’s your cue to fit new struts and bring the Serena’s everyday practicality back to its best.

Popular questions about 2007 Nissan Serena gas struts

Do 2007 Serena models have gas struts on the bonnet?
Most C25 Serenas use a simple prop rod for the bonnet, not gas struts. The gas-filled stays are fitted to the rear tailgate. If a previous owner has added bonnet struts, they’re aftermarket.

How do I know when the Serena tailgate struts need replacing?
Common signs are the hatch not staying up, slow or uneven opening, or needing a shove to lift. Cold mornings often make weak struts show their age sooner. Any oil weep on the strut body is also a giveaway.

Can universal gas struts be used on the Serena?
You’ll want application-matched struts with the correct extended/compressed length, end fittings, and force rating for the C25 tailgate. Using the wrong spec can make the door hard to close or unable to stay up. Check trusted catalogues for Serena-specific units.
