Parts for your 2000 Nissan Serena-Gas struts

2000 Nissan Serena gas struts — what they do and when to replace them

Based on the Nissan Serena C24 service manual (Body/Doors section, which identifies a gas-filled “Back Door Stay”) and Nissan FAST electronic parts catalogue entries for the C24 (1999–2005) listing a “Stay Assy – Back Door,” plus aftermarket catalogues from Stabilus Lift-O-Mat and Monroe/StrongArm that supply tailgate gas springs for this model, gas struts are indeed fitted to the 2000 Nissan Serena. They support the rear tailgate. The bonnet on this model typically uses a manual prop rod, not gas struts.

On a 2000 Serena, the rear gas struts do the heavy lifting: they counterbalance the weight of the tall, wide tailgate so owners don’t have to wrestle it open or worry about it crashing down. Each strut is a sealed, nitrogen-charged damper designed to push the tailgate smoothly through its arc and hold it at full height, even on blustery days at the beach or when loading the pram and the chilly bin.

With age, heat and dust, gas pressure and internal seals deteriorate. Tell-tale signs it’s time to replace them include:

• The tailgate won’t stay up or sags in cooler weather.
• Slow, jerky opening or a need to “help” it past halfway.
• Oil misting around the rod or noisy operation.

Owners are best to replace tailgate struts in pairs. Mixing an old weak unit with a fresh one can twist hinges and gives uneven support. It’s a quick job with basic tools, but safety matters:

1. Support the tailgate securely with a prop or a mate lending a hand.
2. Pop off the metal retaining clips at each ball joint, then lever the strut free.
3. Clip the new struts on with the rod pointing down when fitted, so the internal oil keeps the seals lubricated.

A tidy Serena benefits from a couple of simple habits: keep the ball-studs clean and lightly greased, avoid forcing the tailgate when frozen or heavily iced, and don’t try to “re-gas” old struts — they’re sealed units, so replacement is the go. Quality aftermarket struts matched to the C24’s tailgate weight bring back that easy one-hand lift and solid hold, making day-to-day use safer and far less of a workout.

FAQs

Do all 2000 Nissan Serena models have gas struts on the tailgate?
Yes. Technical references for the C24 generation specify gas-filled back door stays for the rear tailgate across the range. Variations exist by trim and market, but the function and fitment of tailgate gas struts are consistent.

Does the 2000 Serena use gas struts on the bonnet?
No. The bonnet typically uses a manual prop rod. Only the rear tailgate uses gas struts from factory on this model year.

Can worn Serena tailgate struts be re-gassed, or should they be replaced?
They’re sealed units, so re-gassing isn’t recommended. Replacement with correctly rated new struts is the reliable fix, and doing both sides together keeps lift and hold even.
