Parts for your 2016 Toyota Wish-Gas struts

2016 Toyota Wish gas struts — what they do and how to look after them

Based on technical sources, gas struts are fitted to the rear tailgate of the 2016 Toyota Wish (ZGE20/25 series). Toyota’s service literature for the model family includes a Back Door – Back Door Stay procedure that identifies gas-pressurised stays on the rear door, and the Toyota Electronic Parts Catalogue lists “Stay Sub‑Assy, Back Door” (LH/RH) as gas-filled supports for 2009–2017 Wish variants. Application catalogues from major OE suppliers (e.g., Stabilus Lift-O-Mat and Monroe Max-Lift) also specify rear liftgate gas springs for this vehicle. The bonnet on this model uses a prop rod rather than gas struts.

On a 2016 Toyota Wish, the tailgate gas struts do the heavy lifting—literally. Charged with nitrogen gas and a dab of oil for damping, they support and control the rear door so it opens smoothly and stays put without wobble or slam. As the car ages, pressure naturally bleeds off and seals wear, which is why a hatch that used to glide up can start sagging, squeaking, or need a helpful shoulder on cooler mornings.

As part of routine servicing, it pays to check the tailgate action. A tech will look for uneven lift, oily film around the rod ends, or any sticking. They’ll also listen for groans and watch for bounce on closing. If one strut is tired, the other won’t be far behind—replacement is best done in pairs for balanced support and to protect the hinges and latch.

• Signs they’re due: tailgate drops or won’t hold, slow lift (especially in cold weather), visible leaks, or bent/loose ball sockets.
• Care tips: keep the chrome rods clean, wipe with a soft cloth only. Don’t grease the rods—oils attract grit and damage the seals.
• Replacement basics: support the tailgate safely, note the orientation (cylinder body usually up), pop off the spring clips, swap both struts, and verify smooth, secure operation.

Quality struts last years, but climate and usage matter. Vehicles that live outdoors or see frequent load space use will tire their stays sooner. Fresh gas struts restore that easy, one-hand lift and keep the rear door secure—handy when loading the weekly shop or the kids’ kit in a windy Kiwi or Aussie arvo.

FAQs

Do all 2016 Toyota Wish models have gas struts?
Yes—on the rear tailgate. The bonnet uses a manual prop rod from factory. Aftermarket bonnet strut kits exist, but they’re not original equipment and should be chosen carefully to avoid hinge stress.

How long do the rear gas struts last, and when should they be replaced?
Typically 5–10 years depending on climate and usage. Replace when the tailgate no longer holds up, rises sluggishly, shows oil weep, or needs assistance to open—preferably both sides together for even support and safety.

Can a home mechanic replace the tailgate gas struts?
Usually yes. Support the door with a prop or helper, then release the retaining clips and swap the struts one at a time. Avoid gripping the chrome rod with tools, and check the door opens fully and holds before removing the support.
