Parts for your 2005 Toyota Kluger-Exhaust mount

2005 Toyota Kluger exhaust-mount: what it does and how to look after it

Yes, the 2005 Toyota Kluger uses exhaust-mounts. Toyota’s repair manual and Electronic Parts Catalogue (EPC) for the 2004–2007 Kluger/Highlander platform (ACU25/MCU28) show multiple rubber exhaust insulators—often called exhaust-mounts or hangers—supporting the front pipe, centre section and rear muffler. They’re standard kit on this model and essential to how the exhaust is held in place.

On the Kluger, each exhaust-mount suspends the exhaust from the body with a rubber isolator. That rubber lets the system move a touch under load and heat expansion, while soaking up engine and road vibration. The result: fewer rattles in the cabin, the pipe and mufflers sit at the correct height, and there’s less stress on joints, flanges and the catalytic converter. If a mount perishes or stretches, the exhaust can sag, knock on crossmembers or the rear subframe, and clamp loads can shift—eventually causing leaks or cracked welds.

There’s no fixed replacement interval for exhaust-mounts on a 2005 Kluger, age, heat and climate do the damage. As a rule of thumb, start checking them from about the 8–10 year mark, or around 150,000–200,000 km, and anytime the vehicle sees lots of towing or rough roads.

• Signs a mount needs attention: exhaust thuds over bumps, a tinny rattle at idle, a tailpipe that sits off-centre, or visible splits and glazing in the rubber.
• Service tip: during routine servicing, inspect each insulator and the steel hangers. Look for cracks, hardening, elongation of the holes, and surface rust on brackets.
• Replacement advice: support the exhaust with a stand, spritz the old insulators with silicone spray, then lever them off the pegs. Fit quality EPDM or OEM-style insulators, avoid petroleum-based lubes on rubber. Replace mounts in pairs on the same section to keep the system level.
• After fitment: confirm the tailpipe sits evenly in the bumper cut-out, check for at-least-finger clearance to heat shields, and recheck after a few heat cycles.

DIYers will find this a straightforward job with basic tools, but always work on a cool exhaust and use proper stands. For bracket bolt torque and any model-specific quirks (e.g., AWD versus 2WD layouts), follow the Toyota workshop manual.

Popular questions about 2005 Toyota Kluger exhaust-mounts

How many exhaust-mounts does a 2005 Kluger have?
Most 2005 Kluger variants use roughly four to six rubber mounts, depending on engine and exhaust layout. Expect one near the front pipe, one around the centre section, and two at the rear muffler. Some trims may add an extra insulator near resonators or heat shields.

Can universal exhaust hangers be used?
Yes, but pick quality EPDM rubber and match the hole spacing and thickness to the Kluger’s pegs. Poorly sized universals can leave the system sagging or too tight, which invites knocks or premature wear. OEM-style insulators usually fit best and keep noise down.

What causes exhaust-mounts to fail early?
Heat cycling, oil contamination, and road salt speed up ageing. Frequent towing or corrugations also work the rubber harder. Keeping oil leaks sorted and checking mounts at each service helps them last the distance.
