Parts for your 2009 Ford Mondeo-Gas struts

2009 Ford Mondeo gas struts — what they do and when to replace them

Based on technical sources including Ford ETIS/Workshop Manual (Mk4/BA7 body closures), the Haynes Ford Mondeo 2007–2014 manual, and OE/aftermarket catalogues such as Ford Microcat and Stabilus Lift-O-MAT, the 2009 Ford Mondeo hatch and wagon (estate) are fitted with gas-charged support struts on the tailgate. The bonnet uses a prop rod from factory, and most sedans use torsion bars on the boot rather than gas struts. So gas struts are absolutely relevant on the 2009 Mondeo—specifically for the rear tailgate on hatch and wagon models.

On a Mondeo hatch or wagon, gas struts take the heavy lifting out of opening the tailgate and keep it safely parked overhead. They control the speed of lift and stop the lid from crashing down—especially important on breezy days or when the weather turns cold. Over time, the nitrogen charge and internal seals wear, which is why older struts feel lazy or let the tailgate sag.

Servicing-wise, they’re low-fuss but worth a quick check at every service interval. A good rule of thumb is to inspect operation every 10,000–15,000 km or annually.

• Wipe the chrome shafts clean, don’t grease them—oil attracts grit and damages seals.
• Check for oily misting around the rod seal, bent shafts, or loose ball-stud mounts.
• Note temperature effects: a weak strut will be most obvious on cold mornings.

Replacement is straightforward and best done in pairs to keep lift balanced. Support the tailgate with a prop or a mate’s hands, then flick the retaining clips with a small flat screwdriver and pop the sockets off the ball studs. Fit the new struts rod-end down (as most manufacturers specify for lubrication), press them onto the balls, and make sure clips are fully seated. It’s a 10–20 minute job with basic tools.

When choosing replacements, match the body style (hatch or wagon) and build date to ensure the correct Newton (N) rating and end fittings. OE numbers vary by VIN, and reputable aftermarket listings will specify the right force and stroke. If the tailgate needs a shove to start moving, creeps down on its own, or won’t stay up, it’s time for fresh struts—your back and your rear window will thank you.

• Replace in pairs for even lift and proper latch alignment.
• Avoid using the strut body as a handle—grab the tailgate, not the cylinder.
• Dispose of old struts safely, they’re pressurised.

Popular questions about 2009 Ford Mondeo gas struts

Are bonnet struts fitted to the 2009 Mondeo?
From factory, the 2009 Mondeo uses a prop rod for the bonnet, not gas struts. Aftermarket bonnet-strut kits exist, but they’re add-ons and not part of the original equipment.

How can someone tell the tailgate struts are failing?
Signs include the tailgate dropping or not staying up, sluggish lift (worse in cold weather), a need to “push” it open, or an oily film on the rod. Any of these mean the internal charge or seals are tired.

Should the struts be replaced in pairs?
Yes. Replacing both maintains balanced force, proper opening height, and reduces stress on hinges and the latch. It’s an inexpensive, quick job that restores a like-new feel.
