Gear box mountings Volvo 240 (M46)

A sagged or cracked gearbox pad often shows up as a jolt when shifting, vibration in the floor or a dull thud when the power comes on. The rubber hardens and cracks over the years, and then the box wanders in the tunnel, which can also stress the universal joints and exhaust system. On the 240 with the manual M46 box, the rear mounting is a recurring check point when renovating the drivetrain.
