Parts for your 2008 Subaru Forester-Gas struts

2008 Subaru Forester gas-struts: what they do, and when to replace them

Yes, gas-struts are used on the 2008 Subaru Forester. Subaru’s factory service information and parts catalog list gas-charged “rear gate stays” for this model, which are the struts that hold the tailgate up. The bonnet on this generation uses a manual prop rod from the factory, while the tailgate relies on a pair of gas struts to safely lift and support the door.

On a 2008 Forester, the tailgate gas-struts do the heavy lifting—literally. They counterbalance the weight of the rear door so it opens smoothly and stays put overhead, even on a breezy day or when it’s loaded with a spoiler and wiper assembly. Over time, the internal gas pressure and seals can fade, especially after years of Aussie or Kiwi summers and chilly mornings. That’s when the tailgate starts to feel heavy, creeps down on your head, or needs a helping hand to open.

As part of routine servicing, it’s smart to give the tailgate struts a quick check:

• Open the tailgate fully and see if it holds position without drifting down.
• Listen for hissing and look for oil misting around the rod—both signs of wear.
• Test on a cold morning, weak struts often show up worse in low temperatures.

If any of that sounds familiar, replacement is the go. Always replace in pairs to keep lift effort and holding strength balanced. The job is a straightforward DIY for most owners: support the tailgate safely with a prop or a helper, flick back the small retaining clips at each end of the strut, pop the strut off the ball studs, and click the new ones on. Don’t remove the clips completely—just lift them enough to release. Avoid gripping or greasing the chrome rod, contaminants chew out the seals and shorten the strut’s life.

Workshops will often bundle this with a service if the struts are tired, because it’s a quick win for safety and convenience. Whether doing it at home or at a garage, always support the tailgate while the struts are off and follow the vehicle’s service guidance. With fresh gas-struts, the 2008 Forester’s tailgate will lift cleanly and stay rock steady, making daily use a whole lot nicer.

Popular questions about 2008 Subaru Forester gas-struts

Do all 2008 Foresters have gas-struts on the bonnet?

No. The 2008 Forester uses a manual prop rod for the bonnet from factory. Gas-struts are fitted to the rear tailgate. Bonnet gas-struts are an aftermarket upgrade if you want hands-free lifting at the front.

How long do tailgate gas-struts typically last?

It varies with climate and use, but many last 5–10 years. Heat, dust, and lots of open/close cycles can shorten that. If the tailgate sags, needs help to lift, or drops in the cold, it’s time to replace them—ideally as a pair.

Can I replace the tailgate struts myself?

Yes, if you’re handy. Support the tailgate securely, release the small retaining clips, swap the struts, and click the clips back down. Take care—those doors are heavier than they look. If you’re unsure, a workshop can do it quickly during a service.
