Symptoms & Engine Signals

The most common sign of a worn torque strut mount, also known as the dog bone mount, is a distinct clunking or knocking sound from the engine bay when you accelerate or decelerate, particularly in stop-and-go driving conditions common in Kingston. This mount is located at the bottom rear of the engine and is specifically designed to control forward and backward engine movement under torque loads. When the rubber bushing deteriorates, the metal inner sleeve can contact the outer housing, producing a metallic knock that is easily audible inside the cabin. You may also feel a corresponding vibration through the floorboard during acceleration, and the engine may rock noticeably when you open the bonnet and observe it during a rev test. In more advanced cases of bushing failure, the excessive engine movement can cause the exhaust system to knock against the vehicle’s underbody, producing additional noises that can be mistaken for loose exhaust components or failed suspension bushings. The torque strut mount is particularly prone to wear in vehicles driven aggressively or in stop-and-go traffic conditions, as each acceleration and deceleration cycle loads the mount and progressively fatigues the rubber element.

Why Your Car Might Be Struggling

The torque strut mount, also referred to as the lower rear engine mount or dog bone mount, performs a highly specific function in the engine mounting system: it controls the rotational movement of the engine and transmission assembly around their longitudinal axis under the influence of engine torque. When the accelerator is pressed, the engine rotates in one direction as it delivers power to the transmission, and when the throttle is lifted, it rotates in the opposite direction under compression and drivetrain resistance. The torque strut mount is designed with a precisely calculated rubber durometer and geometry to allow controlled amounts of this rotational movement while preventing excessive motion that could cause component contact. The mount’s rubber element is subjected to intense and repeated loading cycles throughout its service life, as each throttle application and release produces a corresponding load on the mount. Over time, the rubber fatigues and develops cracks, particularly at the bond line where it joins the metal mounting surfaces. In the tropical Jamaican climate, the combination of high underbonnet temperatures and road heat accelerates the rubber degradation process, leading to premature mount failure. When the bushing fails completely, the engine can rotate sufficiently to cause the cooling fan to contact its shroud, the exhaust to strike the subframe, and the intake system to rub against the strut tower brace or bonnet insulation. Replacing the worn mount with a quality Lemforder component restores proper engine positioning and eliminates the knocking and vibration that have been affecting your driving experience.
