Parts for your 2013 Daihatsu Bego-Gas struts

2013 Daihatsu Bego gas struts

Based on Daihatsu/Toyota technical references for the J200-series Terios/Bego (workshop manual body section and EPC listings), the 2013 Daihatsu Bego is fitted with a gas-charged damper on the side-hinged rear door (often called a back door damper or gas strut). The bonnet is supported by a prop rod, not gas struts. So gas struts are absolutely relevant on the back door of this model.

On the Bego, the gas strut helps control the swing of the rear door, steadies it in wind, and stops it from slamming or drifting shut on a slope. That makes loading the boot safer and less of a wrestle, especially with the spare wheel mounted on the door adding extra weight. Over time, the strut’s internal gas pressure and sealing can fade, which shows up as a door that feels heavy, won’t stay put, or moves too freely.

As part of routine servicing, it’s smart to give the back door strut a quick once-over. Wipe the chrome shaft with a clean cloth, check for oil misting or dents, and make sure the mounts are snug. Avoid spraying silicone or greasy lubes on the shaft—those can damage the seals. If the shaft is pitted or rusty, or the door no longer feels controlled, replacement is the right call rather than trying to “re-gas” it.

• Common signs it’s on the way out: door swings too fast, won’t hold position, squeaks or knocks at the hinges, visible oil around the strut body, or sluggish action in cold weather.

Replacement is straightforward for a competent DIYer, but mind your fingers. Support the door fully (a helper or a prop is essential), then swap the damper. Many use ball-stud clips—pop the clip, lever the socket off, fit the new unit in the same orientation, and ensure the clips are properly seated. If yours uses bolt-on brackets, mark positions before removal and tighten everything securely. Don’t clamp the shaft in a vice or force-compress a new strut, that can ruin it.

Workshops generally inspect the Bego’s back door gas strut at service intervals and replace on condition. Match the new damper to the vehicle spec so the door opens smoothly but doesn’t over-swing. Given New Zealand and Australian conditions—coastal air, dust, and heat—regular cleaning around the hinges and the strut, plus avoiding leaning on the open door in strong winds, will help it last longer.

Popular questions about 2013 Daihatsu Bego gas struts

Does the 2013 Daihatsu Bego have bonnet gas struts?
No. Technical literature for the J200-series Bego shows a prop rod for the bonnet. The gas-charged damper is on the side-hinged rear door only.

How can someone tell if the rear door gas strut needs replacing?
If the door swings too freely, won’t hold its position, or there’s oil misting on the strut body, it’s due. Pitting on the shaft, clunks at the mounts, and poor control in wind are also giveaways.

Is it safe to replace the rear door strut at home?
Yes, if the door is properly supported and the correct part is used. Keep hands clear of the hinge area, don’t compress the new strut by hand, and make sure all clips or bolts are fully seated before removing the support.
