Parts for your 2006 Daihatsu Terios-Gas struts

2006 Daihatsu Terios gas struts — what’s actually fitted and why

Based on technical references — the Daihatsu Terios J200-series workshop manual (Body: Back Door, Engine Hood) and the Toyota/Daihatsu Electronic Parts Catalogue for the J200 Rush/Terios — the 2006 Daihatsu Terios is not fitted with gas-lift struts for the rear door or the bonnet. The rear is a side-hinged door with a door check/stopper assembly, and the bonnet is supported by a simple prop rod. Those official sources list a “back door check/stopper” and “hood stay (prop rod)”, with no gas strut components specified for this model year.

Why no gas struts? It comes down to the design. The Terios’s rear door swings sideways and carries a spare tyre, so it doesn’t lift upwards like a hatch. Gas struts are designed to counterbalance an upward-opening tailgate, a side-swing door relies on robust hinges and a door check to control the opening sweep and hold the door in set positions. On the front, Daihatsu specified a prop rod for the bonnet to keep costs and complexity down — common practice for compact SUVs of the era.

So, if someone is hunting “2006 Daihatsu Terios gas struts,” what they usually need is one of these related parts or checks instead:

• Back door check/stopper (sometimes called a door stay) — inspect for wear, binding, or fluid seepage if a damper type is fitted.
• Rear door hinges and latch — lubricate and check for sag or misalignment, especially with the spare hanging off the door.
• Bonnet prop rod and clips — ensure the rod isn’t bent and the retaining clip still holds securely.

Tell-tale signs things need attention include the rear door swinging too freely on a slope, not holding in the usual detent, clunks from the hinges or check strap, or a bonnet prop rod that won’t stay clipped. Replacing a worn back door check/stopper is straightforward for a technician and restores controlled opening. It’s not recommended to retrofit gas struts to the Terios’s side-hinged rear door — the hinges, mounting points and door structure weren’t engineered for gas-spring loads, and add-on kits can stress the panelwork and misalign the latch.

As part of regular servicing, a quick lube of the hinges and latch, an inspection of the door check/stopper, and confirming the bonnet prop rod and clip are in good nick will keep the Terios feeling solid and safe to use.

FAQs

Does the 2006 Daihatsu Terios have gas struts on the tailgate?
No. The J200-series Terios uses a side-swing rear door with a mechanical door check/stopper, not gas-lift struts. Official workshop and parts references list a back door check and hinges, and the bonnet is supported by a prop rod.

Can gas struts be retrofitted to the Terios rear door?
It’s not recommended. The door and hinges weren’t designed for gas-strut loads, especially with the spare tyre mounted. Retrofits can stress the mounting points, affect alignment and latching, and may require engineering approval to be safe and compliant.

What should be serviced instead of gas struts?
Have the back door check/stopper, hinges and latch inspected and lubricated, and replace the check/stopper if it’s loose, noisy or leaking. Up front, make sure the bonnet prop rod is straight and its clip holds firmly.
