Parts for your 2010 Mitsubishi Outlander-Exhaust mount

2010 Mitsubishi Outlander exhaust-mount: what it does and when to replace it

Technical sources confirm the 2010 Mitsubishi Outlander is fitted with exhaust mounts (also called exhaust hangers or insulators). The Mitsubishi workshop manual for the CW-series Outlander shows multiple rubber hangers supporting the front pipe, centre section and rear muffler, and the Mitsubishi ASA electronic parts catalogue lists “exhaust insulator” items for this model. Aftermarket parts catalogues in Australia and New Zealand also carry direct-fit exhaust mount rubbers for the 2010 Outlander, so the part is absolutely relevant to this vehicle.

On this Outlander, exhaust mounts are small rubber isolators that suspend the exhaust from the underbody. Their job is to keep the pipe and muffler positioned correctly while soaking up vibration, so passengers don’t cop excess noise, harshness or rattles. When the rubber perishes or stretches, the system can sag, knock on the subframe over bumps, or develop an annoying drone at certain revs.

As part of routine servicing, a quick look under the car pays off. The mechanic (or a switched-on DIYer) should check each hanger for cracks, splits, hardening, or oil contamination. If one mount is on the way out, it’s smart to replace the pair on that section so the exhaust sits level. Use quality OEM-equivalent rubber or an appropriate high-temp polyurethane where available.

Handy tips for replacement and care:

• Inspect every 10,000–15,000 kilometres or at each service, and before a WOF or rego check.
• Support the exhaust with a jack and a block of wood before popping mounts off.
• A dab of silicone spray helps slide the hangers on and off the pegs without a fight.
• Watch clearances around heat shields, rear bumper and driveshafts, adjust as needed.
• If the exhaust still sits crooked after new mounts, look for a bent bracket or fatigued clamp.

Signs it’s time for new mounts on a 2010 Outlander:

• Thudding or tapping from the rear over speed humps.
• Tailpipe sitting low or off-centre in the bumper cut-out.
• Rubber hangers visibly cracked, glossy/hardened, or oil-soaked.
• New exhaust drone or vibration that wasn’t there before.

They’re inexpensive, quick to fit, and can save the cost of a cracked weld or dented muffler if addressed early. Keeping the mounts fresh helps the Outlander stay quiet and comfy on Aussie and Kiwi roads alike.

Popular questions about 2010 Mitsubishi Outlander exhaust mounts

How often should exhaust mounts be replaced on a 2010 Outlander?
There’s no fixed interval. In normal use, many last 5–10 years, but heat, road grime and towing can age them faster. Inspect at each service and replace at the first signs of cracking, sagging or hardening. If you’ve just fitted a new exhaust, fresh mounts are a good idea.

Can worn exhaust mounts cause rattles or drone?
Yes. When mounts soften or split, the exhaust can touch shields, the subframe or the rear bumper. That contact creates knocks over bumps and can introduce a low-frequency drone at certain revs. Restoring proper support and clearance with new mounts usually sorts it.

Are polyurethane mounts better than rubber for the Outlander?
Polyurethane can be tougher and resist heat and oil better, great for heavy towing or rough roads. The trade-off is a firmer connection that may transmit a touch more vibration. For daily driving, quality OEM-style rubber is typically the best balance of comfort and longevity.
