Parts for your 2013 Subaru Tribeca-Exhaust mount

2013 Subaru Tribeca Exhaust Mount (Hanger) — Purpose, Care, and Replacement

Yes, the 2013 Subaru Tribeca is fitted with exhaust mounts (often called exhaust hanger cushions). Technical documentation confirms this: the Subaru Factory Service Manual for MY2013 Tribeca (Exhaust section) specifies multiple hanger cushions and brackets along the system, and the Subaru parts catalogue lists OE rubber hangers used to support the centre pipe and rear mufflers. These elastomer mounts are standard NVH hardware on the Tribeca’s H6 exhaust, keeping the pipework supported and isolated from the body.

On this model, the exhaust mounts do the heavy lifting of suspending the exhaust while soaking up vibration and road shock. They keep the mufflers and piping aligned in the tunnel, maintain ground and body clearances, and allow for heat expansion without stressing flanges or the catalytic converters. When the mounts harden, crack, or stretch, owners will often notice a thud over bumps, a rattly tailpipe, or the exhaust sitting off-centre in the rear bumper cut-out.

Servicing-wise, it’s smart to inspect the mounts at every routine service or tyre rotation. In Aussie and Kiwi conditions, think every 10,000–15,000 km checks, and replacement on condition. OE-style rubber hangers preserve factory comfort, firmer polyurethane options can reduce movement on rough tracks or with towing, but may add a touch of cabin buzz.

Common signs a Tribeca exhaust mount needs attention:

• Rubber perishing, cracking, or tearing
• Sagging tailpipe or muffler contacting a heat shield
• Clunks, squeaks, or metallic tapping on start-up or over bumps
• Excessive side-to-side movement at the mufflers
• Visible missing or mismatched hangers after impact or off-road use

Replacement is straightforward workshop work: safely support the exhaust, lube the pegs with silicone spray, swap the hanger, then confirm clearances around the subframe, towbar, and rear bumper. It pays to replace mounts in pairs across the rear to keep things even. Aftermarket towing set-ups or a knocked heat shield can change clearances, so a post-fit check drive for knocks is worth it.

How often should the exhaust mounts be replaced on a 2013 Tribeca?

There’s no fixed interval—replace on condition. Have them checked every service, many last well beyond 100,000 km, but heat, towing, and gravel roads can age them faster.

Can polyurethane hangers be used instead of OE rubber?

Yes. Poly hangers curb movement and can help with heavy towbar loads. Expect slightly more vibration at idle compared with OE rubber, which is quieter and comfier for daily use.

What noises point to a worn Tribeca exhaust mount?

Listen for dull thuds over speed humps, a rattle at start-up, or tapping near the rear bumper on rough roads. If the tailpipe isn’t centred, that’s another giveaway.
