How to Solve the Exhaust Pipe Vibration Issue in Prado?
2 Answers
Prado exhaust pipe vibration can be resolved by: 1. Replacing the connecting device between the exhaust pipe and the engine; 2. Replacing the rubber rings connecting the exhaust pipe and the frame; 3. Replacing the exhaust pipe; 4. Cleaning the throttle body, fuel injectors, and intake manifold; 5. Adjusting the position of the chassis suspension. The Prado is a mid-to-large-sized SUV. Taking the 2019 Prado Automatic Premium Edition as an example, its body dimensions are: length 4840mm, width 1885mm, height 1890mm, wheelbase 2790mm, fuel tank capacity 87L. It is equipped with a 3.5L naturally aspirated engine, with a maximum power of 206kW and a maximum power speed of 6000rpm.
My Prado also had exhaust pipe shaking issues before, and it took quite a while to fix it. The common cause is the aging or damage of the exhaust pipe's mounting hangers, which leads to shaking, especially after off-roading when vibrations intensify. First, lift the car to check if the hangers are corroded or broken. Leaking gaskets at the connections can also worsen the shaking. When the engine runs unevenly, such as unstable idling, it can amplify the exhaust pipe's resonance. It's best to have a friend help start the engine while you observe the shaking points from underneath the car and try tightening the screws. If that doesn't work, you'll need to go to a professional repair shop to replace the hangers or the entire exhaust pipe. My experience is that early intervention brings peace of mind, preventing accidents from parts shaking loose on the road. The Prado is often used for off-roading, so the exhaust pipe area is prone to impacts. Pay extra attention to the bracket condition during regular car washes—prevention is low-cost.
