A front-end clunk over bumps is usually worn sway bar links, bushings, strut mounts, or control arm bushings. Here’s what to check first and when to stop driving.
What's likely causing that front-end clunk
On a Subaru Outback VI, a clunk from the front suspension over bumps and potholes is almost always a worn or loose component in the sway bar, strut, or control arm system. The most common culprit is the front stabilizer bar (sway bar) end links and bushings. They take a beating on rough roads, and when the bushings harden or the links develop play, you'll hear a dull rattle or clunk at low speeds. Next on the list are the front strut mounts and bearings, the lower control arm bushings, and the ball joints. Loose strut mounting bolts or a worn top mount can also clunk over sharp bumps. On higher-mileage cars, a worn CV axle or loose brake caliper can mimic suspension noise, so a proper inspection matters.
