Engine mountings B230 Volvo 700/900 (1988-)

Shaking at idle or a thud when you hit the gas can point to tired motor pads – a common wear item on the B230 cars in the 700/900 series, where the rubber hardens and cracks over the years. When a pad sags the motor shifts and can knock against adjacent parts, so the mounting is a good check point on high-mileage examples.
