Parts for your 2012 Subaru Exiga-Gas struts

2012 Subaru Exiga Gas Struts — What they do and when to replace them

Gas struts are indeed used on the 2012 Subaru Exiga. Factory documentation lists gas‑pressurised “Stay Assembly – Back Door” units on the rear liftgate, providing the lift and controlled lowering of the tailgate. This is shown in the Subaru Global Service Manual for the EXIGA YA series (Body/Rear Gate procedures covering back door stays) and the Subaru electronic parts catalogue (FAST) for YA4/YA5 models, which both specify gas stays for the back door. The bonnet on many trims is supported by a prop rod rather than gas struts, as outlined in the hood section of the same service manual.

On the Exiga, rear gas struts do the heavy lifting: they counterbalance the tailgate’s weight so it pops up smoothly and stays put overhead. That means easier loading, less strain on the hinges, and safer hands when the weather turns windy.

Like any sealed, nitrogen‑charged damper, they wear over time. Cold mornings can make tired struts show their age, and a heavy tailgate garnish or accessories can hurry them along. As part of regular servicing, a quick check is smart: open the tailgate fully and see if it holds its height without drifting, listen for creaks, and look for oil misting on the strut body.

• Common signs they’re due: tailgate sags or won’t stay up, slow or jerky lift, hissing or visible oil, needing two hands to raise.
• Best practice: replace in pairs to keep lift even and predictable.

Replacement is a straightforward job with the right care. Support the tailgate securely with a stand or a helper. Pop the metal retaining clip at each ball joint with a small flat screwdriver (don’t fully remove the clip), ease the old strut off, then press the new one onto the ball studs until it clicks. Avoid gripping the polished rod with pliers, and don’t lubricate the rod—just keep it clean. If brackets are removed, refit using factory torque specs from the Subaru manual.

Choosing the correct spec matters. Use Exiga‑specific struts with the proper Newton rating and end fittings from a reputable supplier. Keeping the tailgate hinges lightly lubricated and the seals clean reduces load on the struts, helping them last longer. Never heat, puncture or incinerate old struts, treat them as pressurised items and recycle according to local guidelines in Australia or New Zealand.

FAQs

How long do the rear gas struts last on a 2012 Subaru Exiga?
Most owners see around 5–10 years, but climate and usage matter. Frequent beach trips, temperature swings, or an accessory‑laden tailgate can shorten their service life. If the gate won’t hold itself up or feels lazy on cool mornings, it’s time.

Do they need to be replaced in pairs?
Yes. Replacing both keeps lift balanced and ensures the new strut isn’t overworked by an older, weaker mate. It also restores the original opening height and smooth action.

Can a home mechanic change them?
Absolutely, provided the tailgate is safely supported. The job is usually clip‑off, clip‑on. Follow the Subaru service manual steps, keep hands clear of pinch points, and never lever against or mark the chrome rod.
