Parts for your 2016 Subaru Forester-Gas struts

2016 Subaru Forester gas struts: what they do and when to replace them

Based on the Subaru Forester SJ-series Service Manual (Body/Rear Gate—Stay) and the Subaru Electronic Parts Catalogue for MY2016, this model is factory-fitted with gas-charged struts on the rear tailgate (including power tailgate variants). The bonnet uses a manual prop rod (as shown in the Owner’s Manual lift procedure), not gas struts. So yes—gas struts are absolutely relevant on the 2016 Forester, specifically for the rear gate.

On a 2016 Forester, the tailgate gas struts do the heavy lifting: they counterbalance the door, slow and smooth the motion, and hold it safely open so there are no surprise head knocks. They’re nitrogen-filled dampers designed to work across a wide temperature range and through years of daily use. When they’re healthy, the tailgate glides up with a reassuring feel and stays put, even in a bit of wind.

Like any wear item, gas struts gradually lose pressure. Common signs they’re tired include a tailgate that sags or won’t stay up, slow movement (especially on cold mornings), a jerky action, or an oily film around the rod seal. If one side fails, the other’s not far behind—always replace them as a pair to keep things balanced and avoid stressing hinges or, on power models, the drive unit.

• Inspection: ask the workshop to check tailgate hold and motion at each service (every 10–15,000 km works well). Any hesitation or drop is a cue to test with a support prop.
• Care tips: keep the piston rods clean, don’t lubricate the chrome rods (oil attracts grit and chews out seals). Avoid using the tailgate as a handle to swing the car shut.
• Replacement: support the gate safely, flick up the spring clips, and pop the ball joints off. Fit the new struts with clips facing out. It’s a quick job with the right prop and takes most techs 10–20 minutes. Power tailgate models may require a basic position reset per the service/owner guidance.

Quality matters. Choose struts matched to the SJ Forester’s spec (VIN-based selection is best). A fresh pair brings back that smooth, confidence-inspiring lift and keeps the tailgate behaving properly for years.

Popular questions

How long do Forester tailgate gas struts typically last?
Most see 5–8 years, depending on climate and how often the tailgate’s used. Cold weather can make ageing struts feel weaker, so if it’s droopy in winter, test again on a warmer day—if it’s still sluggish, it’s time for new ones.

Can they be replaced at home?
Yes, if the correct support is used to hold the tailgate up and you’re handy with basic tools. The key is safety—use a proper prop or a helper. Replace both sides, and don’t pry the clips right off, just lift them enough to release the sockets.

Why does my tailgate drop in cold weather?
Gas pressure drops with temperature, so marginal struts show their age when it’s chilly. If it won’t hold reliably in the cold, the struts are near the end of their life and should be replaced before they become a safety risk.
