Parts for your 2000 Subaru Legacy-Strut mounts

2000 Subaru Legacy strut mounts — what they do and when to replace them

Based on technical references including the Subaru Factory Service Manual for the 2000 Legacy (BE/BH), the Subaru FAST parts catalogue, and major suspension catalogues from KYB and Monroe, the 2000 Subaru Legacy uses MacPherson struts in the front and a strut-type rear suspension. That means it’s fitted with strut mounts (also called top mounts or insulators) at all four corners. These mounts sit at the top of each strut assembly, tying the suspension to the body while isolating noise and vibration.

On this Legacy, the strut mounts carry the vehicle’s weight, allow the strut to pivot when steering, and keep road harshness out of the cabin. Over time, the rubber insulator can crack or compress, and the bearing (in the front mounts) can bind or wear. If left too long, worn mounts can cause clunks over bumps, vague steering, tramlining, or a creak when turning the wheel at low speed. Tyre feathering and inconsistent ride height at a corner can also point to tired mounts.

There’s no fixed service interval for strut mounts, but it’s smart to inspect them every 40,000–60,000 km or whenever tyres are rotated, especially if the car sees rough rural roads or corrugations common around Aus and NZ. Look for perished rubber, separated bonding, rusty or mushroomed centre studs, or gritty/rough steering feel. Any time new struts are fitted, budgeting for new mounts and boots is good practice, it saves labour later and helps the new dampers do their best work.

When replacing, fit quality mounts designed for the BE/BH Legacy and always follow safe spring-compression procedures. After installation, get a proper wheel alignment — ride height and top-mount position affect camber and caster on this platform. Fresh mounts can noticeably sharpen steering response, quieten the front end, and restore that planted Subaru feel in the wet. For owners chasing longevity, pairing new mounts with new upper spring seats, bump stops and dust boots keeps the front end tight for years.

• Tell-tale signs: clunks over speed humps, steering “notching”, wandering at motorway speeds, or visible cracking at the mount.
• Best practice: replace mounts with struts, torque fasteners to spec, and align immediately after.

Popular questions about 2000 Subaru Legacy strut mounts

Do both front and rear struts on a 2000 Legacy use top mounts?
Yes. The BE/BH Legacy runs a MacPherson-style front and a strut-type rear suspension, each using a dedicated top mount/insulator to attach the strut to the body and control noise and vibration.

What symptoms suggest the strut mounts need replacing?
Listen for clunks over potholes, creaks when turning the wheel at parking speeds, or a steering wheel that won’t self-centre smoothly. Uneven tyre wear and a slight drop in ride height at one corner can also point to worn mounts.

Should the mounts be replaced when fitting new struts?
It’s recommended. Old mounts can transfer noise and reduce the life of new dampers. Replacing mounts, bearings, boots and bump stops at the same time minimises repeat labour and keeps the front end tight and quiet.
