What are the symptoms of a broken transmission mount pad?

[GiaMarie]

Engine mount pad failure symptoms include idle steering wheel vibration, body vibration, and loud body resonance noise. The engine mount pad is an elastic structure that connects the engine to the frame, significantly reducing the transmission of engine vibration to the vehicle body, which can cause passenger discomfort. Function of engine mount pads: Engine mount pads serve as the connection between the powertrain and the vehicle body. Their main purposes are to support the powertrain, reduce the impact of powertrain vibration on the vehicle, limit powertrain vibration amplitude, and play a crucial role in the vehicle's NVH performance. The mount pads are used to install the engine on the frame, isolating engine resonance and primarily serving as vibration dampers. Lifespan of mount pads: Under normal use, engine mount pads can last over 6 years with no specific replacement interval. However, they must be replaced immediately if inspection reveals signs of cracking, aging, or corrosion. Generally, mount pads are replaced after exceeding 150,000 kilometers, with some vehicles not requiring replacement until over 200,000 kilometers or even longer.
