Parts for your 2012 Mitsubishi Outlander-Strut mounts

2012 Mitsubishi Outlander strut mounts

Strut mounts absolutely apply to the 2012 Mitsubishi Outlander. The factory service manual’s Front Suspension section specifies a MacPherson strut layout on the front axle, and Mitsubishi’s ASA parts catalogue lists the upper strut mounting/insulator and bearing for this model. Major aftermarket catalogues (KYB, Monroe) also list front strut mounts for 2012 Outlander variants. The rear uses a multi-link setup with separate shocks, so no rear strut mounts there—just conventional shock mounts.

Up front, the strut mount (often called a top mount or insulator) bolts the strut assembly to the body and isolates vibration with a thick rubber layer. It also houses a bearing so the strut and spring can rotate smoothly when steering. On a 2012 Outlander, healthy mounts keep things quiet, help the steering self-centre, and protect the cabin from harshness on coarse Aussie and Kiwi roads.

Because the rubber and bearing live a tough life—heat, water, dust, and constant load—wear is normal, typically showing up from medium to higher kilometres or earlier on rougher routes. Common symptoms include:

• Clunks or knocks over bumps, especially at the top of the strut tower
• Creaking or graunching when turning the wheel at low speed
• Notchy or vague steering feel, poor return-to-centre
• Vibration through the column and accelerated or uneven tyre wear

Inspection is straightforward during a service: look for perished or cracked rubber, separation around the centre sleeve, rusty cups, and binding as the spring turns. Given how interconnected the front end is, it’s smart to replace mounts in pairs and to fit new bearings when doing front struts. Many technicians will also refresh the dust boots and bump stops at the same time.

Replacement involves compressing the coil spring, so correct tooling and safety are critical. Refit with the spring correctly clocked, use new top nuts where specified, and torque fasteners to spec from the service manual. A wheel alignment afterwards is a must—ride height and camber/caster can shift slightly with fresh components. In typical Australian and New Zealand use, front strut mounts often last well past 80,000 km, but frequent corrugations, heavy loads, or big potholes can shorten that. Keeping tyres balanced and pressures right helps them live longer.

• Service tip: if the steering feels notchy with the car stationary, suspect the strut mount bearing first.
• Best practice: replace both front mounts together to keep steering feel consistent left-to-right.

Popular questions about 2012 Mitsubishi Outlander strut mounts

Do both front strut mounts need replacing at the same time?
While you can change one, it’s recommended to do both. Mounts age similarly, and replacing in pairs keeps the steering feel and ride height even across the front. It can also save on duplicate labour and alignment costs.

How long do strut mounts last on a 2012 Outlander?
Many see service life beyond 80,000–150,000 km, but it varies with driving conditions. Rough rural roads, heavy towing, and bigger aftermarket wheels typically shorten lifespan. Regular inspections during services will catch wear before it causes tyre issues.

Can worn strut mounts cause tyre wear or steering shudder?
Yes. A sloppy mount lets the strut move around, which can alter alignment under load and create uneven tyre wear. A binding mount bearing can also cause shudder or a notchy feel as you turn the wheel, especially at parking speeds.
