Parts for your 2010 Mazda Premacy-Gas struts

2010 Mazda Premacy gas struts

Technical references show the 2010 Mazda Premacy (also known as Mazda5 in some markets) uses gas-filled struts on the rear tailgate, while the bonnet is supported by a prop rod, not struts. This is documented in Mazda’s Workshop Manual for the CR/CW Premacy/Mazda5 (Body – Doors/Liftgate) and the Mazda Electronic Parts Catalogue for 2010, which list two liftgate support cylinders and associated ball-stud fittings.

The rear gas struts do the heavy lifting on a 2010 Mazda Premacy’s tailgate. They counterbalance the door’s weight so it lifts smoothly, holds itself up without drama, and closes in a controlled way. That means fewer surprises in the car park and less strain on hinges and latch gear. Good struts make loading prams, groceries, or camping gear easier and safer, especially on a windy day.

As with any pressurised, sealed component, gas struts wear gradually. Temperature swings, dust, and age reduce their internal gas charge and the efficiency of the seal. Telltale signs include the tailgate dropping in cold weather, a sluggish or uneven rise, needing a push to get moving, or visible oil weep around the shaft. If any of that sounds familiar, it’s time to inspect them.

Best practice is to replace in pairs so lift is even side to side. Match the original length, end fittings (usually ball-socket with retaining clips), and force rating specified for your exact build (spoilers, glass and trim can change spec). During servicing, a quick check every 10,000–15,000 km is smart: wipe the rods clean with a soft cloth, make sure the clips are fully seated, and inspect the ball studs for play. Don’t lubricate the chromed shaft—oils and silicone sprays can attract grit or swell seals. Keep the area clean and dry instead.

DIY replacement is straightforward: prop the tailgate securely with a suitable support (never rely on a weak strut), flick the metal clips back with a small flat screwdriver, pop the old strut off, then press the new one on and ensure the clips lock home. Avoid removing both struts at once unless the tailgate is firmly supported. Most automotive gas struts are sealed and not designed to be re-gassed, replacement is the reliable fix. Expect typical service life of five to ten years depending on climate and usage. Dispose of old struts responsibly—being gas-charged, they should be de-pressurised by a recycler or handled per local guidelines.

• Common symptoms of failure: tailgate won’t stay up, drops quickly, rises slowly, or shows oil around the shaft.
• Safety tip: always support the tailgate before removing a strut.

FAQs

How long do the tailgate gas struts last on a 2010 Mazda Premacy?
Many owners see five to ten years from a set, but heat, cold, and frequent use can shorten that. If the tailgate sags, won’t hold up, or needs a shove to start moving, it’s time to test or replace them.

Can the Premacy’s gas struts be re-gassed, or should they be replaced?
Most OEM-style struts on the 2010 Premacy are sealed and not intended for re-gassing. Replacement with correctly spec’d new struts is the dependable, cost-effective solution.

Is it OK to change just one strut?
It’s technically possible, but replacing in pairs is recommended. Uneven force can twist the tailgate slightly, stressing hinges and causing inconsistent opening and closing.
