Parts for your 1999 Subaru Forester-Strut mounts

1999 Subaru Forester Strut Mounts

Strut mounts are absolutely used on the 1999 Subaru Forester. Technical references including the Subaru Forester (SF, MY1999) Factory Service Manual front and rear suspension sections, Subaru genuine parts catalogues (listing front and rear “strut mount/insulator” assemblies), and application guides from suspension manufacturers such as KYB and Monroe all specify dedicated strut top mounts for this model at both ends.

On the 1999 Forester, the suspension is MacPherson strut front and rear, so the strut mounts (often called top mounts, top hats, or insulators) do a critical job. They locate the top of the strut in the body, isolate noise and vibration with a rubber insulator, and—on the front—house a bearing that lets the strut rotate smoothly as the wheels steer. When healthy, they keep the ride quiet and the steering feel consistent, when worn, they can cause clunks, vague steering, and uneven tyre wear.

As part of routine servicing, it’s smart to check the mounts whenever the Forester is on a hoist. Look for cracked or perished rubber, separated bonding between the rubber and metal plate, loose or rusty studs, and roughness or notching in the front mount bearings. A road test that reveals clunks over small bumps, “memory steer” (steering doesn’t self-centre cleanly), or a creak on low-speed turns points to tired mounts.

There’s no fixed replacement interval, but in Aussie and Kiwi conditions many original mounts are past their best by 150,000–250,000 km. If replacing struts or springs, it’s good practice to fit new mounts at the same time to avoid paying labour twice. Go with quality OE-style rubber mounts to keep NVH civilised, polyurethane options can add noise and harshness on a daily driver.

• Always replace mounts in axle pairs (both fronts or both rears) for consistent handling.
• Use proper spring compressors and follow the workshop manual for reassembly order and torque specs.
• Mark camber bolts before removal and book a wheel alignment after any strut or mount work.
• Inspect related parts while you’re there: dust boots, bump stops, upper spring seats, and bearings.

Done right, fresh mounts sharpen steering feel, quieten the cabin, and help tyres wear evenly—well worth it on an SF Forester that’s still doing the hard yards.

Do 1999 Subaru Foresters use strut mounts front and rear?

Yes. The SF Forester runs MacPherson struts at both ends, so it has dedicated strut top mounts (insulators) front and rear. The front mounts include a bearing to allow smooth steering rotation.

How long do strut mounts last on a 1999 Forester in Australia or New Zealand?

Usage and conditions vary, but many original mounts show wear by 150,000–250,000 km. Frequent gravel roads, heavy loads, and hot climates can shorten service life. Replace on condition—noise, cracking, or rough steering feel are the cues.

Do you need a wheel alignment after replacing strut mounts?

Definitely. Any time struts or top mounts are disturbed, alignment can shift. A post-repair alignment helps prevent odd tyre wear and ensures the Forester tracks straight.
