Parts for your 2011 Subaru Forester-Strut mounts

2011 Subaru Forester strut mounts: what they do, and when to sort them out

Based on the Subaru SH (2009–2013) Forester Factory Service Manual and OEM parts catalogues, the 2011 Forester uses MacPherson struts up front with a dedicated upper support/bearing assembly (the front strut mount). At the rear, it runs a double-wishbone layout with separate shock absorbers that attach to an upper mount/insulator. So yes — “strut mounts” are very much relevant on the 2011 Forester, particularly at the front where the mount also carries a steering bearing.

A front strut mount does two key jobs: it anchors the strut to the body and cushions road harshness, and, thanks to its integrated bearing, it lets the strut rotate smoothly as the wheels steer. That rubber-and-bearing combo keeps noise and vibration in check, maintains precise steering feel, and helps tyres wear evenly. The rear shock mounts don’t steer, but they still isolate bumps and keep the back end quiet and composed.

As part of routine servicing on a 2011 Forester, it’s smart to check strut and shock mounts whenever tyres, brakes, or suspension are inspected — especially from 60,000–80,000 kilometres onward, or sooner if the vehicle sees rough roads. Look for cracks in the rubber, torn bushings, rust at the studs, or perished isolators. Up front, rotate the steering at a standstill and listen for graunching or feel for notchy “memory steer”, that often points to a dry or failing bearing in the mount.

Common signs it’s time to replace the mounts include:

• Clunks, creaks, or knocking over bumps
• Notchy steering, poor return-to-centre, or vague on-centre feel
• Uneven tyre wear or a tendency to wander
• Visible splits in the rubber, or water ingress/rust at the top hat

When fitting new front strut mounts, use quality OE or reputable aftermarket units with the bearing pre-fitted. Replace any single-use hardware, set all fasteners to the factory torque spec, and book a wheel alignment — removing the front strut disturbs camber and toe. If you’re refreshing struts or shocks, doing the mounts at the same time saves labour and avoids chasing new noises later. For the rear, inspect or replace the upper shock mounts/insulators with the dampers to keep the cabin quiet and the handling tidy.

Popular questions about 2011 Subaru Forester strut mounts

How long do the front strut mounts typically last?
Many Forester owners see 100,000–160,000 km from front mounts, but life varies with road quality and load. City kerbs, corrugations, and heavy accessories can shorten their lifespan. Replace them on condition — if there’s noise, steering notchiness, or perished rubber, don’t wait.

Do I need a wheel alignment after replacing strut mounts?
Yes, if the front struts are removed. The strut-to-knuckle bolts and strut position influence camber and toe, so an alignment is recommended to protect tyres and restore proper handling.

Can worn strut mounts cause steering vibration or “memory steer”?
They can. A binding or contaminated bearing in the front mount may cause notchy steering or poor return-to-centre, and worn rubber can transmit vibration into the cabin. Fresh mounts usually bring back smooth steering feel and reduce shakes over bumps.
