Parts for your 2013 Nissan Serena-Gas struts

2013 Nissan Serena gas struts — what they do and when to replace them

Based on technical references, the 2013 Nissan Serena (C26) uses gas-charged lift supports on the back door/tailgate. The Nissan Electronic Service Manual for the C26 series (Body/Back Door section) illustrates the “back door stay (gas spring)”, and the Nissan FAST electronic parts catalogue lists the component in group 90450 as “Stay Assy – Back Door” for C26 models. The bonnet typically uses a manual prop rod, and the sliding side doors are on tracks with motors and dampers rather than gas struts. So for this model, “gas struts” are relevant to the tailgate only.

On a 2013 Serena, those rear gas struts do the heavy lifting – literally. They balance the weight of the tailgate, let it open smoothly, and hold it up safely so there’s no head-bonk while loading the pram, groceries or camping gear. They’re sealed units charged with nitrogen and a light oil film for lubrication, so there’s no servicing as such, when they tire out, they’re replaced.

As part of routine servicing or a pre-trip check, it’s smart to give the back door action a quick once-over. If the hatch feels heavy, won’t stay up, sags in a breeze, or slows right down in cold weather, the struts are on the way out. Oily residue on the rod, visible pitting or a rusty rod are also red flags. Most workshops replace them in pairs to keep lift and holding force even.

• Typical signs they’re failing: tailgate drops or won’t stay open, uneven lifting, hissing with oil weep, or sluggish movement in winter.
• Expect lifespan to vary with use and climate, frequent tailgate use or hot/cold extremes shorten life.

1. Always support the tailgate before removal. A prop or an assistant is a must.
2. Note the orientation. Most Serena struts fit ball sockets with spring clips, a small flat-blade screwdriver releases them.
3. Swap both sides, click the new struts onto clean ball studs, then gently cycle the hatch to confirm smooth, even lift.

Quality replacements are matched by length, end fittings and force rating (printed on the strut). A light wipe of the rod with a clean cloth is fine, don’t lubricate the rod or expose it to solvents, as that can damage seals. With fresh gas struts fitted, the Serena’s tailgate goes back to an easy, confidence-inspiring lift and a solid hold at full height.

Popular questions about 2013 Nissan Serena gas struts

How long do the 2013 Nissan Serena rear gas struts usually last?
Service life depends on use and climate, but many owners see 5–10 years. Lots of tailgate cycles, coastal air, or big temperature swings can shorten that. If the hatch no longer stays up or feels heavy, it’s time.

Should both rear gas struts be replaced together?
Yes. Replacing them as a pair keeps lift and holding force even, protects the hinges, and avoids a lopsided feel. Mixing an old soft strut with a new one usually leads to premature wear and poor operation.

What force rating do the Serena’s gas struts use?
The required force is model- and spec-dependent and is printed on the original strut body in newtons (N). Match replacement struts by length, fittings and the printed force rating for the C26 Serena tailgate to ensure correct lift and hold.
