Solutions for Pajero V73 Resonance Issues?
3 Answers
Pajero V73 resonance issues are recommended to be checked at a 4S shop or auto repair shop. Automobile Resonance: Resonance is normal, every vehicle has its own resonance point, but the specific points vary. Some may resonate at 150 mph, others at 120 mph, it's uncertain. The key is whether it affects driving. Any abnormal resonance in a vehicle is considered abnormal and can affect the vehicle's lifespan. It is recommended to have it checked at a 4S shop or auto repair shop. Vehicle Resonance Points: The speed at which resonance occurs varies from vehicle to vehicle. Generally, the higher the speed at which resonance occurs, the better the vehicle's quality. For example, a Volkswagen Santana may start resonating around 100 mph, while a Mercedes-Benz may not resonate until 200 mph. If the vehicle shakes when the air conditioning is turned on, this is not resonance but rather a sign of insufficient engine power.
I've driven the Pajero V73 for several years, and the resonance issue is quite annoying. The most common cause is loose engine mounts or engine mounting components, especially noticeable at high RPMs. When checking, first look for signs of aging or cracking in the mount bushings, and try tightening the mounting bolts with a wrench yourself. If the mounts are damaged, they need to be replaced with new ones, preferably OEM parts for better durability. Additionally, the tension of the engine belt is crucial; if it's too loose, it can cause vibrations, and adjusting the belt tension can help. Also, pay attention to whether the engine runs smoothly at idle. If there's unusual noise, it might be due to carbon buildup. Regularly cleaning the fuel injectors and throttle body can also reduce resonance. If the problem persists, take it to a professional repair shop as soon as possible to avoid causing other mechanical issues. Safety first—don't ignore small problems!
As a car enthusiast's experience, the Pajero V73 often experiences resonance issues in the exhaust system. Loose or corroded exhaust pipes or mufflers can cause severe vibrations at high speeds, sounding like a buzzing noise. Check for gaps or rust at the exhaust hose connections and gently shake the pipes to see if there's noticeable movement. If you can handle it yourself, start by tightening the connection bolts with a wrench. If the hose is aged or deformed, replace it with a new one, making sure to choose a high-temperature-resistant material. Additionally, a clogged catalytic converter can also cause resonance, making the car feel sluggish and vibrate when accelerating. Regular cleaning or replacement of the catalytic converter components is necessary to prevent carbon buildup. I recommend checking the exhaust system every six months as part of routine vehicle maintenance. If you can't pinpoint the source, take it to a 4S shop for a comprehensive diagnosis instead of wasting time guessing.
