2018 Toyota Land Cruiser Gas Struts — What They Do and When to Replace Them

Based on technical references including the Toyota Owner’s Manual (Land Cruiser 200 Series, 2018), the Toyota Electronic Parts Catalogue, and fitment guides from major OE strut manufacturers, the 2018 Toyota Land Cruiser is fitted with gas struts on the bonnet and the upper section of the split tailgate. They assist lifting, hold the panel safely when open, and, on vehicles with a power back door, work alongside the motor to manage the door’s weight.

On this model, gas struts are all about controlled movement and safety. They make the bonnet easy to lift and stop it from dropping on hands, and they support the upper tailgate so loading gear doesn’t become a wrestling match. When they’re healthy, the panels glide open and stay put, when they’re tired, everything feels heavier, and the door or bonnet may sag or drift down.

As part of routine servicing for a 2018 Land Cruiser, it’s smart to check the struts annually. A quick visual once-over and a functional test can save a nasty surprise in the driveway or on a steep track. Typical lifespan in Aussie and Kiwi conditions is often 5–8 years, but heat, dust, coastal air, and added accessories can shorten that.

• Signs they’re due: the panel won’t stay up, opens slowly, drops in cold weather, or shows an oily film on the rod.
• Service tips: keep the rods clean and dry, never grease the shafts (it damages seals), avoid using the panel as a climbing aid.
• Replacement advice: swap struts in pairs, support the panel securely, and don’t compress new struts by hand. On power back doors, weak struts overwork the motor, so replace promptly.

For touring setups with added weight (roof ladders, accessories on the upper tailgate), uprated struts may be needed. Match length, end fittings, force rating, and temperature suitability. Always dispose of old struts properly—pressurised units shouldn’t be drilled or crushed at home.

Done right, fresh gas struts restore that effortless lift-and-hold feel the Land Cruiser is known for, and they keep the big 200 Series safer and easier to live with day to day.

Popular questions about 2018 Toyota Land Cruiser gas struts

How long do gas struts last on a 2018 Land Cruiser?
In local conditions, many last 5–8 years. Harsh heat, beach work, and extra tailgate weight can shorten that window. If the upper tailgate or bonnet won’t stay up, treat that as due.

Do gas struts need lubrication?
No. Lubricants attract grit and can swell the seals. Keep the chrome rods clean and dry. If they’re dirty, wipe gently with a soft cloth—no sprays on the shafts.

Can they be replaced at home?
Yes, with care. Support the panel securely, swap one side at a time, and use the correct strut spec. For power back doors, follow manufacturer procedures to avoid straining the motor.
