Parts for your 2006 Subaru Forester-Engine mount

2006 Subaru Forester engine-mount — purpose, servicing and replacement

Yes, the 2006 Subaru Forester is fitted with engine mounts. Subaru’s factory service manual for the 2006 Forester and the official Subaru genuine parts catalogue both show left and right engine mounting insulators along with a transmission mount. That means the engine-mount is absolutely relevant to this model, helping secure the EJ-series boxer engine to the subframe while controlling vibration and movement.

The engine-mount’s main job is to support the engine’s weight and isolate noise, vibration and harshness, so the cabin stays calm and the driveline stays aligned. On a Forester, the horizontally opposed engine produces unique vibration characteristics, quality mounts keep those vibes out of the cabin and stop the motor rocking under throttle, braking and on rough Kiwi and Aussie roads.

• Common signs of worn mounts: extra vibration at idle, a thud or clunk on take-off or over bumps, shudder when shifting from Park to Drive, visible splits or sagging in the rubber, or excessive engine movement under the bonnet.
• Ignoring failed mounts can stress exhaust joints, CVs, hoses and wiring, and can contribute to poor shift quality.

Service advice for a 2006 Forester: there’s no strict replacement interval, but a quick visual check at every service (or roughly every 20,000 km) is smart. Look for perished rubber, collapsed height, or oil contamination. If one side has failed, replacing both engine mounts as a pair is often the best value to keep balance and NVH in check. Choose quality OEM or reputable aftermarket mounts designed for the Forester’s boxer layout.

Replacement is a straightforward but safety-critical job: support the engine from underneath with a proper stand or brace, never just a jack. Follow the correct loosening and tightening sequence and torque specs from the service manual. If the front crossmember is loosened, a wheel alignment check is a good idea. After installation, re-check fasteners at the next service.

Maintenance tips that extend mount life include fixing oil leaks promptly (oil softens rubber), ensuring the idle is smooth and within spec, and avoiding repeated clutch dumps or shock loads. A tidy set of engine and transmission mounts will make this Forester feel tighter, shift more cleanly and keep drivetrain components happier over the long haul.

• Popular questions about 2006 Subaru Forester engine-mount

How long do engine mounts last on a 2006 Subaru Forester?
With gentle use and no fluid leaks, mounts can often last 150,000–250,000 kilometres. Frequent towing, hard launches, or persistent oil contamination can shorten that considerably. Regular inspections during routine servicing will catch deterioration early.

Can worn engine mounts damage other parts?
Yes. Excessive engine movement can stress exhaust flex joints, radiator hoses and wiring, and contribute to driveline shudder. It can also make automatic shifting feel harsh or clunky. Replacing tired mounts restores alignment and protects these components.

Should both engine mounts be replaced at the same time?
It’s recommended. If one mount has collapsed, the other is usually not far behind. Replacing them as a pair restores balance and NVH control, and can save on labour compared with doing them separately.
