2008 Subaru Exiga Gas Struts — What They Do and When to Replace Them

Gas struts are indeed used on the 2008 Subaru Exiga — specifically on the rear tailgate. Factory fitment is confirmed by the Subaru Exiga (YA series) Service Manual, Body section (“Rear Gate” – lifter removal/installation) and the Subaru FAST electronic parts catalogue, which lists Stay Assy – Rear Gate, RH/LH for MY2008 Exiga models. The bonnet uses a prop rod from factory, so bonnet gas struts aren’t fitted as standard. Aftermarket catalogues (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) also list rear gate gas springs for the 2008 Exiga.

On the Exiga, the tailgate gas struts do the heavy lifting, supporting the hatch smoothly and keeping it open without fuss. Over time, they lose charge or seep a little oil, and that’s when the tailgate starts to feel heavy, doesn’t rise cleanly, or sags — especially on a cold morning. As part of regular servicing, it’s smart to do a quick check: open the tailgate and see if it holds at full height, look for oily residue on the strut bodies, and listen for creaks. If it droops or needs a shoulder to prop it up, the struts are due.

Replacement is straightforward, but safety first — always support the tailgate with a prop or a helper before popping the clips. Most Exiga owners will replace gas struts in pairs to keep lift and damping balanced. Quality OE-equivalent gas springs are pre-charged and install with simple ball-and-socket fittings. If the original clips are reusable, refit them properly, otherwise, use the supplied hardware. After fitting, cycle the tailgate a few times to ensure smooth, even motion.

There’s no fixed interval for gas struts, but in Aussie and Kiwi conditions they often last 5–10 years depending on usage and heat exposure. Keeping the strut shafts clean helps the seals, avoid grabbing or clamping the shiny rod, and don’t lubricate it — oil attracts grit and can damage the seals. If a bike rack, tailgate tent, or extra accessories have been added, consider higher-rate struts matched to the added mass, but never exceed manufacturer recommendations.

Quick signs it’s time to replace:

• Tailgate won’t stay up or drops suddenly.
• Slow or jerky opening, worse in cold weather.
• Visible oil misting on the strut body.

Fresh gas struts make daily use safer and smoother, restoring that confident, one-hand lift every Exiga owner expects.

Popular questions about 2008 Subaru Exiga gas struts

How can someone tell if their Exiga’s tailgate struts are failing?
Typical giveaways are a heavy or sagging tailgate, slow or uneven lifting, and needing to hold it up by hand. Cold mornings often make weak struts obvious. A light film of oil on the strut body or rod is another red flag.

With the car parked level, open the tailgate fully. If it can’t hold position or drops a few centimetres, the gas charge is likely down and replacement is due.

Should both tailgate struts be replaced at the same time?
Yes. Replacing in pairs keeps lift force and damping balanced. Mixing an old strut with a new one can cause uneven loading, faster wear, and a tailgate that doesn’t open or hold consistently.

Can stronger gas struts be fitted for added accessories?
It’s possible to spec a higher-rate strut to offset modest added weight, but they should be correctly matched. Overly strong struts can stress hinges and make closing difficult. If unsure, stick with OE-spec or seek advice with the actual accessory weight measured.
