2007 Toyota Crown Gas Struts — What They Do and When To Replace Them

Based on technical references — including the Toyota Electronic Parts Catalog for the S180-series Crown (GRS18x/UZS186, 2003–2008) and Toyota Repair Manual procedures for the hood support — gas-charged struts are fitted to the bonnet on the 2007 Toyota Crown. For the boot, most grades use torsion bars (with a small damper on some variants) rather than full gas struts. So yes, gas struts are relevant on this model, primarily for holding the bonnet safely open.

On a 2007 Toyota Crown, the bonnet gas struts do the heavy lifting. They’re nitrogen-charged, sealed units that balance the bonnet’s weight so it opens smoothly and stays put without a prop rod. That makes routine checks under the bonnet less of a juggle — handy on a wet day or when topping up fluids at the servo.

Like any wear item, these struts lose pressure over time. Heat, cold and simple age can soften their lift. If the bonnet feels heavy, creeps down, or needs a helping hand to stay up, the struts are likely due. A light oil mist around the rod seal or a faint hiss can also hint at a failing unit.

• Typical signs they’re tired: bonnet drops or won’t hold, slow/jerky motion, or visible oil on the strut rod.
• Service tip: replace in pairs if there are two — it keeps lift balanced and predictable.
• Safety first: always prop the bonnet securely before removing any strut.

Replacement is a straightforward job on the Crown: pop the retaining clips at each ball socket, swap the unit, and refit the clips. Fit them rod-end down where applicable to keep the internal seal lubricated. Avoid gripping or greasing the chrome rod — just keep it clean. Check the mounting ball studs for wear and snug torque while you’re there. Quality struts are pre-charged to the correct force, so there’s no re-gassing on the car.

There’s no strict time/kilometre interval, but many owners find bonnet struts last 5–10 years depending on climate and use. As part of regular servicing, a quick function check — open the bonnet, feel for consistent lift, confirm it holds — is smart. If the Crown variant has a boot damper rather than a strut, the same rule applies: if it no longer controls the lid’s motion, replace it to avoid a lid slam.

Popular questions about 2007 Toyota Crown gas struts

Does the 2007 Toyota Crown have gas struts on the boot as well as the bonnet?
Most 2007 Crown grades use gas struts on the bonnet. The boot typically uses torsion bars and may include a small damper on certain trims. If the boot doesn’t stay up or slams, it’s usually the torsion/damper setup at fault rather than a full gas strut pair.

How long do Crown bonnet gas struts usually last?
In Aussie and Kiwi conditions, bonnet struts commonly last 5–10 years. High heat, frequent opening, and dust can shorten life. If the bonnet won’t hold or feels heavy, replacement is the go — there’s no reliable “re-gas” on-car.

Can gas struts be re-gassed, or should they just be replaced?
For the Crown’s OEM-style units, replacement is the practical fix. They’re sealed nitrogen-charged parts, on-car re-gassing isn’t standard and rarely lasts. New, correctly rated struts restore the proper lift and safety you want at the bonnet.
