Parts for your 2000 Toyota Bb-Gas struts

2000 Toyota bB gas struts

Gas struts are relevant on the 2000 Toyota bB. Toyota’s Electronic Parts Catalogue for the NCP30/NCP31 series lists two “Stay Assembly, Back Door” units for the rear hatch, and the Toyota body repair manual covers removal/installation of the back door support stay. The bonnet on this model uses a prop rod rather than gas struts, a layout echoed in the first‑gen Scion xB (the export twin), whose service manual shows hatch stays and a prop‑rod bonnet.

On the 2000 bB, the rear hatch gas struts do the heavy lifting. They hold the tailgate up safely, control the opening speed so it doesn’t launch skyward, and stop it slamming down on a windy day. That makes loading the weekly shop or a couple of camp chairs much easier, while protecting hinges and glass from harsh shocks. Because they’re sealed, nitrogen‑charged dampers, there’s no real “servicing” to do—when they get weak, they’re replaced.

How to tell they’re due? Typical signs include needing a hand to push the hatch up, the door sagging or drifting down, a dull “hiss” with oily residue on the shaft, or big changes with temperature (fine in summer, droopy in winter). On a bB that’s 20‑plus years old, original struts have usually lost enough gas pressure that replacement is the smart, safe move.

• Replace in pairs to keep lift and damping even.
• Support the hatch with a prop or helper before unclipping the old struts.
• Pry up the metal retaining clip at the socket end, then pull off the ball stud—no need to fully remove the clip.
• Avoid twisting or scratching the chrome rod, store new struts rod‑down until fitting.
• Match the newton rating and overall length to the bB’s spec, “heavy‑duty” options can lift higher but may stress hinges and seals.

A quick annual check as part of routine servicing—open/close the hatch a few times, listen for binding, and confirm it holds at full height—keeps surprises at bay. In typical Aussie and Kiwi conditions, quality replacements often last 5–10 years, but coastal exposure and frequent cycling can shorten that. If the bonnet feels old‑school with its prop rod, that’s by design, Toyota didn’t fit gas struts there on this generation.

FAQs

Does the 2000 Toyota bB have gas struts on the bonnet?
No. The bonnet uses a prop rod. Gas struts are fitted to the rear hatch only on this model, as shown in Toyota’s body repair procedures and the parts catalogue.

How often should the bB’s rear hatch gas struts be replaced?
Many last 5–10 years, but age, heat, and use matter. If the hatch won’t stay up or feels heavy, replace sooner—ideally in pairs for balanced lift and damping.

Can one person replace the tailgate struts at home?
Yes, with basic tools and a safe prop for the hatch. Release the retaining clips, swap the struts, and click them onto the ball studs. Take care to support the door at all times.
