2022 Subaru Outback Xt Thud Noise at Slow Speeds on Bumpy Roads

Working hypothesis: Most likely, you’ve got a worn front strut mount or control arm bushing. Both are common at your mileage, especially on Subarus that see rough roads. If the thud is sharper and only on one side, sway bar links are a runner-up. If the noise is from the rear, the diagnosis shifts.

Most likely culprits

• Front strut mount — Known to thud over bumps as the rubber deteriorates, especially at slow speeds.
• Front lower control arm bushing — Dull thud, sometimes with steering wander or vague handling.
• Front sway bar link — Sharper clunk, often when one wheel hits a bump or during turns.

How to narrow it down

1. Bounce each corner by hand — Listen for a thud/clunk. If you hear it at the front, suspect strut mounts or bushings.
2. Inspect strut mounts visually — Look for cracked rubber or separation. If you see it, that’s your culprit.
3. Check control arm bushings — Pry with a bar. Excess movement or torn rubber means replacement.
4. Inspect sway bar links — Grab and twist. If you feel play or see torn boots, links are shot.
5. Drive at slow speed over bumps with windows down — Pinpoint if noise is front, rear, left, or right. That narrows the part.
6. Check for loose lug nuts or wheel fasteners — Just in case, but unlikely unless recent tire work.

Possible parts (if needed)

• Front strut mount
• Front lower control arm bushing
• Front sway bar link

A few questions

• Is the thud more pronounced on one side, or dead center front?
• Any change in steering feel, like looseness or wandering?
• Has any suspension work been done recently (struts, bushings, links)?

If you can answer those, I can zero in on the exact part. Safety note: If the thud is severe or you notice handling changes, get it checked ASAP — suspension failures can get ugly fast.
