Parts for your 2017 Mitsubishi Eclipse cross-Gas struts

2017 Mitsubishi Eclipse Cross gas struts

Based on technical sources, gas struts are absolutely relevant to the 2017 Mitsubishi Eclipse Cross. The Eclipse Cross owner’s manual for the first model year (Oceania) shows the rear tailgate supported by gas‑filled struts, and Mitsubishi’s electronic parts catalogues (ASA/CAPS) list twin liftgate gas springs for GK‑series Eclipse Cross built from late 2017. Reputable aftermarket catalogues (e.g., Stabilus, Monroe) also list direct‑fit tailgate lift supports for 2018‑on Eclipse Cross, covering vehicles produced in 2017. Note: the bonnet typically uses a prop rod, not gas struts, on this model.

On the Eclipse Cross, the rear tailgate gas struts do the heavy lifting: they balance the door’s weight, help it rise smoothly, and hold it open safely while loading the boot. They’re sealed, nitrogen‑charged dampers designed to deliver consistent force across a wide temperature range and resist side‑loads, vibration and dust.

As part of routine servicing, it’s smart to give them a once‑over. Keep the chrome shafts clean and dry, wipe off grit with a soft cloth, and avoid lubricants or silicone sprays on the shafts—these can swell the seals and shorten life. If one strut gets weak, replace them as a pair so the tailgate opens evenly and latches correctly.

• Tell‑tale signs they’re due: tailgate drops or won’t stay up, slow lift in cold weather, needing a big shove to start moving, oily residue on the shaft, or knocking noises at full travel.
• Good practice when replacing: support the tailgate securely (two‑person job), note the clip orientation, pop the retaining clips off with a small flat screwdriver, swap one strut at a time, and ensure the ball sockets snap fully home.

There’s no fixed replacement interval—lifespan depends on use and climate—but many owners see 5–10 years. If the vehicle commonly parks nose‑up or carries a tailgate spoiler or accessories, the extra load can hasten wear. Choosing quality, correct‑force struts matched to the Eclipse Cross (check build year and body code) keeps the tailgate light to lift and steady overhead.

One final safety tip: never try to re‑gas or repair a leaking unit. Gas struts are sealed, once they’re weak or weeping, replacement is the proper fix.

Popular questions about 2017 Mitsubishi Eclipse Cross gas struts

Does the 2017 Eclipse Cross have gas struts from factory?
Yes—two gas‑filled struts support the rear tailgate. Technical documentation (owner’s manual illustrations and Mitsubishi ASA/CAPS parts listings) confirms factory‑fit liftgate gas springs on late‑2017 builds. The bonnet is typically held by a prop rod, not struts.

How long do the tailgate struts last and what are the signs of failure?
Service life varies with climate and use, but many last 5–10 years. Signs include a tailgate that won’t stay up, drops suddenly near the top, lifts sluggishly in cold weather, needs a push to get started, or shows oil mist on the shaft. Replace in pairs for balanced operation.

Can they be replaced at home?
Yes, if comfortable with basic tools. Support the tailgate with a prop or helper, then swap one strut at a time by releasing the small retaining clips and snapping the new units onto the ball studs. Take care with the clips and make sure each end seats fully. If unsure, a workshop can do the job quickly during regular servicing.
