The supporting joint mounting kit contains the bushes, sleeves, and hardware that secure the engine or gearbox support arm (torque strut) to the subframe or body. This arrangement restrains the powertrain from rotating under torque reaction during acceleration and braking. Worn bushes in the supporting joint allow excessive engine movement, causing a characteristic thud on acceleration and deceleration, knocking from the engine bay, and in severe cases accelerated wear on driveshaft constant-velocity joints. Febi Bilstein, Lemförder, and Meyle supply replacement mounting kits in OE and heavy-duty polyurethane specifications for a wide range of front-wheel-drive and all-wheel-drive vehicles.
Engine and gearbox mount wear produces distinctive symptoms that worsen progressively. The powertrain should remain almost stationary relative to the body during normal driving — any visible rocking indicates mount wear.
Most front-wheel-drive vehicles have three or four engine/gearbox mounts: two or three rubber-to-metal mounts that carry the static weight, and a torque strut that resists rotational movement. The supporting joint or torque strut bush is the most likely to allow rocking under load because it experiences the highest dynamic forces.
Support the engine and gearbox with a jack and wooden block before removing the torque strut or supporting arm. The rubber bushes can often be pressed out and replaced without removing the arm from the vehicle. Torque the new fasteners to specification — an undertorqued mounting will move, quickly destroying the new bush.
