Parts for your 1999 Daihatsu Terios-Exhaust mount

1999 Daihatsu Terios Exhaust Mounts

Yes, the 1999 Daihatsu Terios uses exhaust mounts (rubber hangers/insulators). This is confirmed by the Daihatsu Terios J100/J102 workshop manual’s Exhaust System section, which illustrates the muffler and tailpipe supported by rubber insulators and hanger brackets, the Daihatsu Electronic Parts Catalogue (EPC) listings for exhaust mounting insulators for the J100-series, and common aftermarket fitment catalogues (e.g., Bosal/Walker) that supply multiple exhaust mounting rubbers for the 1997–2005 Terios. So the exhaust-mount is absolutely relevant for this vehicle.

On a 1999 Terios, the exhaust mounts do the quiet work: they suspend the pipes and mufflers under the car, isolate engine and road vibration, and let the exhaust move a touch as the drivetrain twists or the body flexes off-road. They also keep the tailpipe sitting neatly in the bumper cut-out and maintain safe clearance from the floor, fuel tank and driveline. When the rubbers harden, crack or tear, the system can sag, rattle on bumps, or thump the body, and that’s when a cheap bit of rubber can feel like a big headache.

As part of regular servicing, it’s smart to eyeball the mounts every 10,000–15,000 km (or at each service/WOF). The Terios’ short wheelbase and 4WD use often mean more articulation and heat cycling, so mounts cop a fair hiding on corrugations, when towing a little trailer, or after creek crossings. Look for perished rubber, splits around the holes, shiny scuff marks on the exhaust or crossmembers, and any bracket rust. If the tailpipe’s gone crooked or starts tapping the rear bumper, that’s a giveaway too.

Replacement is straightforward and inexpensive. There are usually several mounts along the system—one near the front pipe/cat area, one around the centre muffler, and a pair at the rear muffler. Support the exhaust with a jack and a wood block, spritz the old rubbers with silicone spray, and lever them off the pegs with a hook or long-nose pliers. Fit quality OEM-type rubber, polyurethane hangers are tougher but can pass a bit more noise into the cabin. Once fitted, make sure the exhaust sits naturally with even clearances and no hard contact points. Give all bracket bolts a once-over with a spanner, and if the metal hangers are flaky with rust, sort them before they become the next rattle.

• Common signs your Terios needs new mounts:
  • Rattles or clunks over bumps
  • Droopy or off-centre tailpipe
  • Visible cracks/tears in the rubber
  • Exhaust knocking the floor or bumper

How many exhaust mounts does a 1999 Terios have, and where are they?

Most 1999 Terios (J100/J102) use several rubber hangers: typically one supporting the front/centre section and two around the rear muffler, though exact count can vary with exhaust spec or aftermarket systems. They’re located on steel pegs welded to the exhaust and body brackets near the centre and tail section.

When checking, follow the pipe from the cat back to the tail—each place the pipe “hangs” on a rubber insulator is one mount.

What are the signs the mounts need replacing?

Look for perished or split rubber, a sagging exhaust, rattles on start-up or bumps, and the tailpipe touching the bumper. Fresh scrape marks on the pipe or crossmembers often mean the system is moving more than it should.

If the Terios suddenly gets boomy inside or knocks on take-off, the rear mounts are prime suspects.

Can they be replaced at home, and what fits?

Yes—if the car is safely supported and the exhaust is cool. Use silicone spray and a hook tool to slip the rubbers off. Most owners stick with OEM-style rubber insulators sized for the J100-series, aftermarket equivalents with the correct hole spacing and thickness work fine.

Avoid universal mounts that stretch the exhaust into a bind, alignment and proper clearance are more important than stiffness alone.
