Parts for your 2008 Nissan Serena-Gas struts

2008 Nissan Serena gas struts — what they do and when to replace them

Technical references confirm the 2008 Nissan Serena (C25 series) uses gas-filled lift supports on the rear tailgate. The Nissan Factory Service Manual for the C25 (Body: Doors/Back Door) details removal and installation of the back door stay, and the Nissan Electronic Parts Catalog (FAST/EPC) lists the “Stay Assy – Back Door” as a gas-charged support. Major aftermarket catalogues (e.g., Stabilus Lift-O-Mat, Monroe, StrongArm) also list tailgate gas struts for 2005–2010 Serena C25. The bonnet on this model typically uses a manual prop rod, not gas struts.

On a 2008 Serena, the tailgate gas struts do the heavy lifting every time the rear hatch is opened. They balance the weight of the big door, keep it stable in wind, and stop it crashing down on heads and hands. When they’re healthy, the hatch lifts smoothly and stays put. As they age, internal gas pressure drops and seals wear, and you’ll notice the hatch gets lazy, sinks in the cold, or needs a helping hand to stay up.

As part of regular servicing, it’s smart to give the struts a once-over. Wipe the chrome rods clean with a soft cloth, check the ball joints and clips for play, and look for a light oil mist or any pitting on the rod surface. Never grease the rod—lubricants attract grit and chew out the seals. If one strut is weak, replace them as a pair so the tailgate opens evenly and the hinges aren’t stressed.

Signs it’s time for new struts include:

• The hatch won’t stay up or drops suddenly, especially on chilly mornings.
• Slow or jerky lift, or needing a shove to get started.
• Visible oil weep, rust, or nicks on the rod.

Replacement is straightforward but safety-first. Support the tailgate with a prop or a mate while swapping struts, and keep fingers clear of the ball sockets. Match the new struts to the Serena C25 spec—length, end fittings, and force rating—so the door doesn’t fling up too fast in summer or fail to lift in winter. If the Serena carries a rear-mounted bike rack or extra glass weight, a slightly higher-force option may help, but don’t overdo it or the latch and hinges can cop it.

Most drivers see 5–8 years out of a set, depending on climate and use. A quick test at every service—open the hatch, let it settle, and see if it holds steadily—keeps things safe and hassle-free for the long haul.

How often should the Serena’s tailgate gas struts be replaced?

There’s no fixed interval, but 5–8 years is common. Heat, cold, and frequent use all speed up wear. If the hatch sags, drops, or struggles to lift, it’s time. Always replace in pairs for even support.

Does the 2008 Nissan Serena have gas struts on the bonnet?

No—most 2008 Serena C25 models use a manual bonnet prop rod. The gas struts are on the rear tailgate only.

Can stronger gas struts be fitted to handle a heavier tailgate?

Yes, modestly higher-force struts can help if there’s added weight like a bike rack. Stay close to OEM spec—too strong and the hatch can open too fast, stress hinges, or make latching harder, especially in warm weather.
