Parts for your 2010 Nissan Serena-Gas struts

2010 Nissan Serena gas struts — what they do and when to replace them

Technical references confirm the 2010 Nissan Serena uses gas-charged struts on the rear back door (tailgate), but not on the bonnet (which is supported by a prop rod). This is documented in the Nissan Serena C25/C26 Service Manual (Body: Back Door “Back Door Stay – Removal and Installation”), the Nissan FAST electronic parts catalogue listing for the back door stay assembly (PNC 90450 group), and common OE-equivalent catalogues from gas spring manufacturers specifying tailgate applications for C25/C26 Serena. So, gas struts are absolutely relevant to the Serena’s tailgate, just not the bonnet.

On the 2010 Serena, the tailgate gas struts take the heavy lifting out of opening and holding the rear door. They’re sealed, gas-charged springs that balance the weight of the tall hatch, so it lifts smoothly and stays put overhead. When they’re healthy, there’s no fuss — no shoulder strain, no sudden drop, and a nice controlled close.

Like any wear item, gas struts fade over time. Cold weather, dust on the rod, and simple age can weaken internal seals and reduce pressure. If the tailgate starts sagging, won’t hold at full height, needs a shove to open, or makes a chattering sound near the hinges, the struts are due. For safety and even lift, it’s best practice to replace them in pairs.

Servicing is straightforward but should be done carefully. Support the tailgate with a prop or a mate before starting. Most Serena struts use clip-retained sockets: ease the spring clip back slightly, pop the socket off the ball stud, and reverse to install the new unit. Don’t lever against the polished rod, don’t twist the cylinder body, and avoid grease or silicone sprays on the rod — they attract grit and damage the seals. A quick wipe with a clean, dry cloth is enough. If the ball studs are dry or creaky, a tiny dab of appropriate lubricant on the ball (not the rod) is fine.

Quality replacements matched to the Serena’s spec will restore effortless lifting and solid hold. During regular servicing, a quick check — does it lift confidently, hold at full extension, and close without slam — helps catch weak struts before they turn into a sore shoulder or, worse, a tailgate that drops unexpectedly.

• Tell-tales: tailgate drifts down, struggles to lift, uneven motion, or oily residue at the rod seal.
• Tips: replace in pairs, support the door, keep the rod clean, and recycle the old units responsibly.

Popular questions about 2010 Nissan Serena gas struts

Do the 2010 Serena’s bonnet and tailgate both use gas struts?
The tailgate does, the bonnet does not. The Serena’s rear back door is supported by gas-charged stays, while the bonnet relies on a prop rod. That’s consistent with the Nissan Serena C25/C26 service documentation and parts listings for the period.

How long do Serena tailgate gas struts last, and what are the signs they’re done?
Many last 5–10 years depending on climate and usage. Signs to watch for are a tailgate that won’t hold at full height, drops in cold weather, needs a shove to open, or leaves oil mist on the rod area. If one’s weak, plan to replace both.

Can a home mechanic replace Serena tailgate struts?
Yes, if they’re comfortable with basic tools and safety. Support the tailgate securely, ease back the retaining clips, swap the struts, and ensure the sockets snap fully onto the ball studs. If the door is heavy or there’s any doubt, get a professional to handle it.
