Parts for your 2022 Toyota C-hr-Gas struts

2022 Toyota C‑HR Gas Struts

Technical documentation confirms that gas‑charged struts are fitted to the rear hatch of the 2022 Toyota C‑HR. The Toyota C‑HR (AX10/AX50) Repair Manual – Body: Back Door details “back door dampers” that hold and control the tailgate. Toyota’s Electronic Parts Catalogue lists “Stay Assembly, Back Door, LH/RH” for 2022 model variants, indicating left and right gas struts on the tailgate. The Owner’s Manual depicts a bonnet supported by a manual prop rod rather than gas struts. So, for this model year, gas struts are relevant for the tailgate, while the bonnet uses a conventional stay.

On the 2022 Toyota C‑HR, the tailgate gas struts do the heavy lifting. They balance the weight of the hatch so it opens smoothly, stays put at full height, and closes in a controlled way. Inside each strut is pressurised nitrogen and a bit of oil for damping. Over time, seals age, gas pressure drops, and performance tails off—especially in colder weather or on vehicles that live outdoors in Aussie or Kiwi coastal conditions.

There’s no fixed service interval, but struts are a wear item. Owners typically notice a few tell‑tale signs when it’s time to swap them out:

• The tailgate won’t stay up or sags, especially on chilly mornings.
• Opening feels heavy, slow, or needs a helping hand.
• One side seems lazier than the other, or the hatch twists slightly.
• Oily film or dirt build‑up on a piston rod from weeping seals.

Replacing tired gas struts on a C‑HR is straightforward with the right gear, but safety comes first: the hatch must be supported with a prop or a mate holding it up. It’s best practice to replace struts in pairs so lift and holding force stay even. Choose parts matched to the C‑HR’s model year and tailgate spec—correct force rating and end fittings matter for proper hold‑open height and latch alignment.

A couple of care tips help struts last: keep the shiny piston rods clean, don’t lube them with grease (it attracts grit and chews out seals), and avoid clamping or forcing a strut fully closed by hand. After fitting, check the opening height in both warm and cold conditions, confirm the latch pulls down cleanly, and re‑torque fasteners per Toyota workshop specs. The C‑HR’s bonnet uses a prop rod from factory, while aftermarket bonnet strut kits exist, they’re not OEM equipment for 2022 models.

How long do C‑HR tailgate gas struts usually last?

Service life depends on climate and use, but many owners see 5–8 years. Frequent tailgate use, heat, and coastal air can shorten that. If the hatch won’t hold up or feels heavy, it’s time for new struts rather than waiting for a sudden drop.

Should both tailgate struts be replaced at the same time?

Yes. Replacing in pairs keeps lift and hold force balanced across the hatch, prevents twisting, and restores the factory open height. Swapping just one can leave uneven support and premature wear on the remaining old strut.

Does the 2022 C‑HR have bonnet gas struts from factory?

No. The 2022 C‑HR bonnet is supported by a manual prop rod per Toyota’s Owner’s Manual. Aftermarket bonnet strut kits are available, but they’re not OEM, fitting one is a modification and should be done carefully to avoid panel misalignment.
