Why Your Hyundai Palisade Clunks Over Bumps — and What to Check First

Most likely causes — check these first

A clunk from the front of your Palisade over bumps is usually a worn or loose suspension part, not a sensor failure. I start with the sway bar end links and sway bar bushings because they take a beating and often sound like a loose hammer when they wear. Then I inspect the strut mounts and bearings, lower control arm bushings, and ball joints. A worn strut mount can clunk over sharp bumps, while a bad control arm bushing often thuds on potholes. Also check for loose brake caliper hardware, a loose underbody shield, or something rolling around in the spare tire well — easy to miss.

• Sway bar end links and bushings — the most common source of front-end clunks.
• Strut mounts and bearings — listen for a clunk when turning or hitting sharp bumps.
• Lower control arm bushings — often thud over potholes and rough pavement.
• Ball joints and tie rods — check for play, torn boots, and steering looseness.
• ABS wheel speed sensor wiring — not a clunk cause, but inspect for damage after a hard hit.

Can you keep driving? If the clunk is mild and steering, braking, and tire wear feel normal, it's usually not an immediate safety emergency — but don't put it off. A worn ball joint or tie rod can fail suddenly and affect steering. If you feel steering play, a shimmy, a pull, or hear a metallic clunk when turning, get it inspected right away.
