Parts for your 2007 Subaru Tribeca-Exhaust mount

2007 Subaru Tribeca exhaust-mount: purpose, upkeep and when to replace

Yes, the 2007 Subaru Tribeca is fitted with exhaust mounts (also called exhaust hangers or cushion rubbers). This is confirmed in the Subaru B9 Tribeca Factory Service Manual (MY2006–2007, Exhaust System section) and the Subaru Electronic Parts Catalog (Group 44 – Exhaust), which both show the exhaust pipe and rear silencer supported by multiple rubber “cushion” mounts attached to body brackets. The same arrangement is depicted in common workshop databases used in Australasia, such as ALLDATA and Mitchell1.

On this model, the exhaust-mounts are simple but critical rubber isolators that hold the centre pipe and muffler in the right spot while soaking up vibration. They stop the system clattering on crossmembers or the rear subframe, help keep the tips aligned in the bumper, and reduce droning in the cabin. Over time the rubber hardens, cracks or stretches thanks to Aussie/Kiwi heat cycles, road grime, and the odd off-bitumen adventure.

Typical tell-tales that the Tribeca’s exhaust-mounts are on the way out include:

• Rattles or thuds on start-up, shut-down, or over bumps
• Exhaust sitting low or skewed in the bumper opening
• Visible splits, perishing, or oil-soaked rubber hangers

As part of routine servicing, it’s smart to inspect the mounts every 10,000–15,000 kilometres. Look for cracking, elongation of the holes, rusted brackets, or missing retainers. A quick spritz of silicone spray can quiet a squeaky mount and make future removal easier, but if the rubber’s perished, replacement is the go—lubricant won’t fix a torn hanger.

Replacement is a straightforward driveway job if the exhaust is cool. Support the system with a jack and a block of wood, then swap one mount at a time so nothing sags. A dab of soapy water or silicone on the pegs makes the new hanger slide on nicely. Inspect the steel brackets for corrosion and renew hardware if it’s crusty. When touching any bracket bolts, tighten to the factory spec listed in the Subaru service manual rather than “by feel.”

OEM-style rubber mounts usually deliver the best comfort and NVH control on a daily-driven Tribeca. Firmer polyurethane options exist and can last longer, but they may add a touch more vibration—fine for some, a bit tiresome for others. Either way, fresh mounts keep the big Subaru quiet, tidy, and happy on long family runs.

Popular questions about 2007 Subaru Tribeca exhaust-mounts

How many exhaust mounts does a 2007 Subaru Tribeca have?
Most vehicles of this type use several mounts along the centre pipe and at the rear silencer—typically four to six on the Tribeca depending on market spec and exhaust layout. A quick visual under the car will confirm the exact count.

What’s the best replacement: OEM rubber or polyurethane?
OEM-style rubber offers factory ride and noise suppression—ideal for family touring. Polyurethane can be tougher and last longer but may transmit a bit more vibration into the cabin. Pick based on comfort preference and how the car’s used.

Can worn exhaust mounts damage other parts?
Yes. A sagging or misaligned exhaust can stress joints, split flex sections, or knock on heat shields and subframes, leading to leaks or cracked welds. Replacing tired mounts early is cheaper than chasing exhaust repairs later.
