Parts for your 2008 Subaru Tribeca-Exhaust mount

2008 Subaru Tribeca Exhaust Mount

Exhaust mounts (rubber hanger insulators) are absolutely used on the 2008 Subaru Tribeca. This is documented in the Subaru Service Manual for the 2008MY Tribeca under the Exhaust System section, and shown in the Subaru electronic parts catalogue (FAST), which lists multiple exhaust pipe hangers/insulators along the system. Major aftermarket catalogues for this model (e.g., Walker, Bosal) also specify direct-fit exhaust hangers for the Tribeca, confirming their fitment.

On a 2008 Tribeca, the exhaust mounts are the small but mighty rubber insulators and brackets that suspend the exhaust from the body. Their job is to hold the exhaust at the correct height and alignment while isolating vibration so the cabin stays quiet. They also prevent undue stress on joints, flanges and the catalytic converter during engine movement, bumps, and heat cycling.

Because these mounts live under the car, they cop heat, road grime, salt spray near the coast, and plenty of flex. Over time, the rubber can harden, crack or stretch. That’s when knocks over bumps, a droopy tailpipe, or a new buzz at idle can appear. As part of servicing a 2008 Subaru Tribeca, it’s smart to give the exhaust mounts a quick look whenever the car’s on a hoist—ideal with every major service or tyre rotation.

• Common signs they’re due: exhaust rattles on start-up, clunks over speed humps, visibly perished or torn rubber, sagging muffler, or exhaust tips sitting off-centre in the bumper.
• Inspection tips: check each hanger from the centre pipe to the rear mufflers, look for splits, elongation of the rubber holes, and rusted brackets or loose hardware.

Replacement is straightforward for a competent DIYer, though any exhaust work should be done on a stable lift or stands. Let the system cool fully, support the exhaust to relieve weight, then lever off the old rubber insulators and press on new ones with a dab of silicone spray. If any metal brackets are bent or corroded, replace those as well. Refit hardware to factory torque as specified in the Subaru service manual, and ensure the system has adequate clearance from the body, heat shields and rear subframe.

For Aussie and Kiwi conditions—heat, towing, or frequent gravel roads—expect to inspect the mounts more often. Fresh mounts are inexpensive insurance against cracked welds, broken hangers, or a fatigued flex joint down the track.

Popular questions about 2008 Subaru Tribeca exhaust mounts

How many exhaust mounts does a 2008 Tribeca have, and where are they?
The Tribeca typically uses multiple rubber hangers from the mid-pipe back to the rear mufflers, including mounts near the centre resonator and one or more around each rear muffler. Exact count can vary by market spec and replacement exhausts, but you’ll usually see three to five mounting points. A quick visual under the car will confirm what’s fitted on your vehicle.

What are the symptoms of a worn exhaust mount on this model?
Look for new vibrations at idle, a metallic knock over bumps, or exhaust tips that sit unevenly in the rear bumper. You may also hear a rattle on cold start that eases as the rubber softens with heat. If the rubber is cracked, stretched, or the hanger pegs are shiny from movement, it’s time to replace.

Is it safe to drive with a broken exhaust mount?
Short distances at low speed might be manageable, but it’s not advisable. A dropped or poorly supported exhaust can stress joints, damage the catalytic converter, or contact heat-sensitive parts. It can also get noisier and risk scraping on the road. Replacing the failed mount promptly helps avoid bigger repair bills.
