Mitsubishi Pajero Gen 4 (2008–2021): Grinding Noise Causes, Troubleshooting & Repair Costs

1. Diagnostic Overview for Mitsubishi Pajero Gen 4 (2008–2021)

When a Mitsubishi Pajero Gen 4 (2008–2021) develops a grinding noise, it indicates severe mechanical friction, typically metal-to-metal brake pad wear against rotors, pitted wheel hub bearings, or transmission gear tooth degradation.

Platform-Specific Advisory: On this vehicle, pay specific mechanical attention to 4M41 upper timing chain guide wear, DPF differential pressure sensor fault, and rear wheel bearing play. Addressing the acoustic symptom early prevents cascading failures in neighboring engine or chassis subsystems.

2. Step-by-Step DIY Mechanical Inspection Checklist

Before taking your Mitsubishi Pajero Gen 4 (2008–2021) to a garage, perform these visual and physical checks safely:

• Visually inspect brake rotor friction rings through wheel spokes for deep gouges or metal scoring.
• Jack up suspected wheel and safely check for 12-to-6 o'clock wobble or roughness when spinning.
• Observe whether grinding noise changes pitch when vehicle weight shifts during left/right sweeping turns.
• Check manual transmission or transfer case fluid level for metallic shimmer or burned odor.

3. Estimated Repair Costs & Part Replacements

Standard workshop repairs for a grinding noise on a Mitsubishi Pajero Gen 4 (2008–2021) typically fall in the range of $220 – $1,150.

Pricing varies based on genuine OEM vs. aftermarket component selection, mechanic labor rates, and whether related hardware (such as mounting bolts, seals, or tensioners) requires simultaneous renewal.
