Parts for your 2018 Mitsubishi Asx-Engine mount

2018 Mitsubishi ASX engine mount — purpose, checks and replacement

Yes, the 2018 Mitsubishi ASX uses engine mounts. This is confirmed by Mitsubishi’s factory Workshop Manual for ASX/RVR/Outlander Sport (2018 model year), which details the engine mounting insulators and torque supports, and by the Mitsubishi ASA Electronic Parts Catalogue that lists a right-hand engine mounting insulator (engine side), a left-hand transaxle mount, and front/rear roll stoppers depending on drivetrain. General repair guides such as the Haynes manual for ASX/Outlander Sport/RVR (2011–2019) also cover inspection and replacement of these mounts.

On this ASX, the engine mounts secure the engine and transaxle to the subframe and body, while isolating vibration so the cabin stays calm. They also control drivetrain movement on take‑off, gear changes and over bumps, keeping driveshaft angles and exhaust alignment happy and protecting hoses, wiring and the radiator from stress.

As part of routine servicing, it’s smart to have the mounts inspected, especially if the car sees corrugated roads or lots of stop‑start commuting. A quick visual and lever check can spot perished rubber, collapsed or torn insulators, and—on hydraulic designs—any fluid seepage. Typical warning signs include:

• Noticeably more vibration at idle, felt through the seats or steering
• Clunks or a thud on take‑off, shifting, or when backing off the throttle
• Excessive engine rock under the bonnet when blipping the throttle
• New exhaust rattles or driveshaft shudder that appeared out of the blue

Replacement intervals vary with use, but many ASX mounts last 80,000–150,000 km. If one mount has clearly failed, technicians often check the companion mounts as well because extra movement can accelerate wear elsewhere. Quality OEM or equivalent mounts keep NVH close to factory levels.

When replacing, the engine should be safely supported with an engine support bar or jack and block at the sump, then fasteners loosened and re‑torqued at normal ride height. It’s wise to follow the workshop manual’s tightening sequence and torque specs, and to recheck for any contact between the engine, subframe and exhaust after a short road test. Driving long‑term with a failed mount isn’t ideal—besides cabin buzz, it can stress the exhaust flex joint, hoses and even the radiator.

Popular questions about 2018 Mitsubishi ASX engine mounts

How many engine mounts does a 2018 Mitsubishi ASX have?
Most 2WD ASX models use three primary pieces: a right‑hand engine mount, a left‑hand transaxle mount, and a front torque/roll mount. Some variants add a rear roll stopper. Exact count can vary by engine and market spec.

What are the common symptoms of a worn engine mount on an ASX?
Extra cabin vibration at idle, a clunk during take‑off or shifting, visible engine rocking, and new exhaust or driveshaft shudders are the usual clues. Hydraulic mounts may also leak fluid when they collapse.

How much does replacement usually cost in Australia or New Zealand?
Ballpark figures: quality aftermarket mounts are often in the $150–$350 range per mount, OEM typically higher. Labour varies by mount position but is commonly 1–3 hours each. Most owners see a fitted cost per mount somewhere around $350–$900, depending on brand and workshop rates.
