Mitsubishi Pajero IV Front Clunk Over Bumps: Causes & Safety

Why your Pajero IV clunks over bumps

That clunk you hear over bumps and potholes is your Pajero's way of saying something's loose. On the Pajero IV, the front double-wishbone suspension has several wear points, and the noise usually comes from a few usual suspects. The good news: most are cheap to fix. The bad news: if you ignore a worn ball joint or tie rod, you could lose steering control. So let's walk through it step by step.

Start by checking these parts, in this order. A helper to bounce the front end while you listen and feel for play makes this much easier:

• Sway bar links and bushings: The number one cause of clunks over bumps. Worn links or bushings let the bar knock against the control arm. Inexpensive and easy to replace.
• Lower and upper ball joints: Jack up the front and pry the wheel up and down. Any vertical play means the ball joint is worn. This is a safety-critical part—don't delay.
• Control arm bushings: Look for cracked, soft, or missing rubber. Worn bushings let the arm shift and clunk over bumps.
• Shock absorber mounts: Check the top and bottom mounting bolts and bushings. A loose or worn mount can sound like a hammer over bumps.
• Steering rack bushings and tie rod ends: Grab the tie rod and check for play. Worn rack bushings let the whole rack move and clunk.
• Brake caliper bolts and pads: A loose caliper or missing anti-rattle clip can mimic a suspension clunk. Quick to check.

No suspension sensor causes a clunk, but a loose ABS wheel speed sensor or its wiring can rattle and sound similar—so give those a quick look while you're under there. As for safety: if the clunk is only from sway bar links, you can drive gently to a shop. But if you feel steering play, vibration, or the noise is loud and metallic, park it and get it towed. Worn ball joints or tie rod ends can fail suddenly and cause a crash. When in doubt, have a pro inspect it on a lift. Your Pajero is a tough truck, but it needs those front-end parts tight.
