2017 Mitsubishi Eclipse Cross Exhaust Mount: What it does and when to replace it

Exhaust mounts are absolutely used on the 2017 Mitsubishi Eclipse Cross. Mitsubishi’s factory Service Manual for Eclipse Cross (GK1W/GK9W), Group 15 – Exhaust System, details rubber hanger insulators supporting the centre pipe and rear muffler, and the Mitsubishi ASA/parts catalogue lists “Insulator, Exhaust” for those hang points. Major repair databases used by workshops in AU/NZ also illustrate multiple hanger locations on this model. So, the exhaust-mount (rubber hanger/insulator) is relevant and fitted to the 2017 Eclipse Cross.

On this Mitsubishi, the exhaust mounts are tough rubber insulators that suspend the exhaust system under the body. Their job is to isolate vibration, keep the muffler and pipe correctly aligned, and let the system move slightly as the engine rocks or the car hits bumps. Good mounts mean fewer rattles, less droning in the cabin, and proper clearance from the bumper, subframe and heat shields.

• Signs it’s time to replace: rattles on start-up or over bumps, a clunk from the rear, the tailpipe sitting off-centre or too close to the bumper, visible cracks or perishing in the rubber, or the exhaust sagging.
• Replacement tips: let the exhaust cool fully, support the system with a jack and a block of timber, spray silicone or soapy water on the pegs to slide the old insulators off, swap like-for-like (OEM or quality EPDM aftermarket), replace mounts in pairs if one has failed, check brackets and heat shields while you’re there.
• Maintenance advice: at each service or tyre rotation, give the hangers a quick look for splits, hardening, or excessive stretch. A light clean and a dab of rubber-safe silicone can help prevent binding, but if the rubber is cracked or oil-soaked, replacement is the go.

Technicians typically inspect the Eclipse Cross exhaust mounts during routine servicing, especially if there’s a noise complaint. Because failed hangers can let the pipe contact the body or stress a joint, prompt replacement helps avoid bigger repairs like fractured welds or a leaking flange gasket. There’s no fixed kilometre interval—condition-based replacement is best. If the vehicle tows, does gravel-road work, or lives near the coast, check the mounts more often, as heat, salt and movement age the rubber faster. Always follow Mitsubishi workshop procedures and tighten any brackets to spec.

FAQs

Does the 2017 Eclipse Cross have exhaust mounts/hangers?
Yes. The factory service information shows multiple rubber hanger insulators supporting the centre and rear sections of the exhaust on the 2017 Eclipse Cross. They’re standard kit on this model.

How often should exhaust mounts be replaced?
There’s no set interval. Inspect them at regular services and replace when you see cracking, hardening, or if the exhaust sags or rattles. Many last years, but usage, heat and road conditions can shorten their life.

Is it safe to drive with a broken exhaust mount?
It’s not ideal. A failed mount can let the exhaust hit the body, melt the bumper, or stress a joint. Short, gentle trips to a workshop may be OK, but get it fixed promptly to avoid further damage.
