Parts for your 2018 Mitsubishi Eclipse cross-Exhaust mount

2018 Mitsubishi Eclipse Cross exhaust mount

Yes, the 2018 Mitsubishi Eclipse Cross uses exhaust mounts. Mitsubishi’s Eclipse Cross (GK series) workshop information for Group 15A – Exhaust, along with the Mitsubishi ASA electronic parts catalogue (GK1W/GK2W), shows multiple rubber “insulators” and brackets supporting the front pipe, centre pipe and rear muffler. These are the exhaust mounts: heat‑resistant rubber hangers and metal brackets that hold the exhaust in position while isolating noise and vibration.

On this model, the exhaust mounts do the heavy lifting quietly in the background. They keep the system centred under the car, stop the muffler knocking the body over bumps, and soak up engine movement so there’s less drone in the cabin. Over time, heat, road grime and age harden or crack the rubber. When that happens, the exhaust can sag or shift, causing rattles on start‑up, thuds over speed humps, or a buzz at certain revs.

For owners servicing a 2018 Eclipse Cross, it’s smart to treat the exhaust mounts as consumables. Inspect them at each service or at least every 20,000 km. Look for perished or split rubber, elongated holes, missing hangers, or a tailpipe sitting off‑centre in the bumper cut‑out. If one mount has failed, the others are often tired too.

• Common signs they’re due: metallic tapping on cold start, clunking on gear changes, exhaust touching a crossmember, or visible cracking of the rubber insulators.
• Replacement tips: let the exhaust cool fully, support the system with a jack and a timber block, use penetrating spray on bracket bolts, swap one mount at a time to keep alignment, don’t preload the rubber—let the system hang naturally before tightening brackets.
• Parts choice: use OEM or quality aftermarket insulators rated for high heat. Avoid generic soft rubbers that can sag quickly.
• After fitment: check tailpipe clearance to the bumper and suspension, confirm no contact at full droop or lock, and listen for new noises on a short road test.

In Aussie and Kiwi conditions, many originals last 7–10 years, but frequent short trips, towing, rough roads or an aftermarket exhaust can shorten that. If there’s any exhaust contact with the body or subframe, replace the offending mount immediately to prevent damage to heat shields and prevent fumes sneaking forward.

Popular questions

Do all 2018 Eclipse Cross models have exhaust mounts and how many are there?

They all have them. The exact count depends on drivetrain and exhaust layout, but typically there’s a hanger by the front/centre section and multiple insulators at the rear muffler, commonly three to four rubber mounts in total. AWD variants may use an extra bracket due to underbody packaging.

What are the symptoms of a bad exhaust mount on this model?

Expect rattles on start‑up, thuds over bumps, the tailpipe sitting off‑centre, or a steady vibration at certain engine speeds. Visual checks often reveal cracked or stretched rubber, missing hangers, or shiny rub marks where the exhaust has been touching the body.

Can a home mechanic replace the exhaust mounts?

Yes, if they’re comfortable working under the vehicle. Basic hand tools, a safe way to raise and support the car, and a jack to hold the exhaust are the essentials. Swap one mount at a time, avoid forcing alignment, and recheck clearances after a test drive. If bracket bolts are badly corroded or the system needs re‑alignment, a workshop visit is the safer bet.
