Parts for your 2017 Daihatsu Bego-Exhaust mount

2017 Daihatsu Bego exhaust mount — what it does and when to replace it

Yes, the 2017 Daihatsu Bego uses exhaust mounts. Technical sources including the Daihatsu Terios/Bego J200-series workshop manual (Exhaust System section), the Toyota Rush J200 service manual, and the Daihatsu electronic parts catalogue list multiple “muffler hangers” or “exhaust pipe insulators” that suspend the front pipe, centre section and rear muffler on this platform. These rubber mounts are standard hardware on the Bego/Rush/Terios family and are essential for supporting the exhaust while isolating vibration.

On a 2017 Bego, exhaust mounts are the quiet achievers. They’re the chunky rubber insulators that hold the exhaust up under the car, keeping it aligned while soaking up engine movement and road shocks. By decoupling the exhaust from the body, they prevent rattles in the cabin, stop metal-on-metal knocks over bumps, and help protect welds and flanges from fatigue. Typically there are several mounts along the system—commonly one near the front pipe, one around the centre section and two at the rear muffler—so the load is spread and the pipework stays clear of the underbody.

• Common symptoms of tired mounts:
  • Rattling or thuds from the rear on take-off, over speed humps or rough roads
  • Exhaust sitting low or looking crooked in the bumper cut-out
  • Perished, cracked or oil-soaked rubber insulators
  • Clunks when shifting from Drive to Reverse

Replacement is straightforward for a workshop and a sensible bit of preventative maintenance. During routine servicing, it’s worth inspecting each insulator for splits, hardening and elongation. If one is shot, check the rest, replacing them as a set on the affected section often restores proper alignment and reduces future call-backs. A spritz of silicone spray helps slide new mounts on without tearing. After fitment, confirm there’s adequate clearance to the crossmember, rear axle, towbar and heat shields with the vehicle at ride height.

For Aussie and Kiwi conditions—coastal air, heat, and the odd gravel road—rubber ages faster. Vehicles used for towing or with long country kilometres can load up the rear mounts more, so keep an eye on them at each service interval. There’s no fixed replacement schedule, many last 5–10 years, but once cracking or sagging shows, swap them out. OE-spec or quality aftermarket insulators both do the job, aim for rubber hardness similar to factory to maintain the Bego’s comfort and keep boom and drone at bay.

• Quick tips:
  • Never jack under the exhaust—support the system if other components are removed
  • Replace stretched or rusty hangers/brackets along with the rubber insulators
  • Re-check clearances after the first heat cycle, mounts can settle slightly

Popular questions

How many exhaust mounts does a 2017 Daihatsu Bego have?
Most Begos run three to five mounts, depending on trim and exhaust layout—typically one at the front/centre and two at the rear muffler. The exact count can vary with market equipment like towbar fitment and heat shields.

Can worn exhaust mounts cause knocking sounds?
They sure can. Perished or stretched mounts let the exhaust swing and tap crossmembers, the rear axle or the bumper. If there’s a dull thud on take-off or over bumps, or the tailpipe looks off-centre, the mounts are prime suspects.

When should the mounts be replaced?
There’s no set kilometre interval. Inspect them at every service. Replace if the rubber is cracked, hard, oil-soaked or the exhaust sits low. In hot or coastal areas, expect earlier ageing than in milder climates.
