How to Solve the Resonance Issue in Pajero V73?

Only the areas where the chassis armor is applied can be thoroughly cleaned, so it's necessary to go to a professional facility for chassis cleaning. After cleaning, simply spray a layer of chassis armor. The coating will alter the hardness, mass, and dimensional shape of the chassis components, thereby eliminating the resonance.
After driving a Pajero for 15 years, let me tell you, resonance issues require systematic troubleshooting. A common culprit is a deformed engine skid plate contacting the chassis, causing loud clunks over bumps. My old V73 had this last time—the skid plate got dented by a rock, and the steering wheel vibrated noticeably at 1800 RPM. Spending 300 bucks to remove, hammer it flat, and the problem was solved. Also, don’t overlook the exhaust hangers—rubber parts usually degrade after 7-8 years, and a loose exhaust pipe will cause a droning noise. Here’s another unconventional fix: the spare tire carrier! Last year on the G318 highway, unbearable metal scraping noises came from the tailgate—applying grease to the spare tire carrier’s pivot worked instantly. When greasing the driveshaft, pay close attention to the U-joints—if the cross joint wears grooves, it can make the whole body shake. If all else fails, try rotating the tires—uneven tread wear on older tires often triggers vibrations too.
