Parts for your 2022 Toyota Land cruiser-Gas struts

2022 Toyota Land Cruiser gas struts — what they do and how to keep them sweet

Gas struts are absolutely relevant to the 2022 Toyota Land Cruiser (300 Series). They’re fitted to the bonnet and the back door/tailgate (including models with a power back door). This is supported by Toyota’s Owner’s Manual and workshop literature for the J300, which reference the gas stays on the back door and bonnet, and by the Toyota Electronic Parts Catalogue listing “Stay, Back Door” and “Support, Hood” for 2022 models. Major aftermarket catalogues (e.g., Stabilus and Monroe) also list direct-fit gas struts for the LC300’s bonnet and tailgate.

On this Land Cruiser, gas-charged struts do the heavy lifting. They help raise and hold the bonnet securely for servicing, and they control the motion of the tailgate so it opens smoothly and stays put. Even on power back doors, the electric drive works in tandem with gas struts to manage weight and damping. The result is a safer, easier lift with less chance of a tailgate thumping down or a bonnet drifting shut.

As part of regular servicing, a quick gas strut check is a smart move. Wipe the exposed rods with a clean, dry cloth, don’t lubricate them, as oils and greases can damage the seals and attract grit. Inspect the end fittings and ball sockets for play or rust, and make sure the clips are seated. If the bonnet or tailgate feels heavy, rises slowly, won’t stay up (especially in cold weather), or you notice hissing and oily residue near the rod seals, the struts are likely past their best.

Replacement is straightforward for a workshop and is best done in pairs on the same door so lift and hold are balanced. Always support the panel while swapping struts—use a prop and a second set of hands. Choose quality, vehicle-specific units matched to the LC300’s panel weights and, for power back doors, the correct specification for the powered system. In Aussie and Kiwi conditions, many see 5–10 years of service life, but beach use, dust, and big temperature swings can shorten that. Building a quick strut inspection into each service keeps the big Cruiser’s panels operating safely and smoothly.

• Signs they’re due: slow lift, sagging, need to “help” it open, or sudden drop.
• Service tip: never clamp, twist, or paint the rod, avoid aftermarket add-ons on the tailgate that change weight without re-spec’d struts.

FAQs

Does the 2022 Land Cruiser 300 have gas struts on the bonnet and tailgate?
Yes. The LC300 uses gas-charged struts on the bonnet and on the back door. Power tailgate variants still rely on gas struts working alongside the motor to manage weight and damping.

How long do the LC300’s gas struts last, and should they be replaced in pairs?
Expect roughly 5–10 years depending on climate and use. Beach driving, dust, and temperature swings can shorten life. Replace in pairs on the same door to keep lift and hold even and to avoid mix-and-match performance.

Can they be DIY replaced?
They can, but support the panel securely and mind the retaining clips. For power back doors or where additional accessories are fitted, a workshop replacement is recommended to ensure correct spec and safe operation.
