Jeep Cherokee Transmission Mount
Diagnosing Problems of Jeep Cherokee Transmission Mount
While they basically consist of nothing more than two metal plates and a block of rubber, the transmission mount of the Jeep Cherokee is responsible for various tasks such as securing the transmission and minimizing engine noise and vibration. This is why once the transmission mount breaks down, it needs to be repaired or replaced as soon as possible to avoid any serious mechanical problems in both the engine and transmission. In this article, we'll break down some of the common problems associated with Jeep Cherokee transmission mounts and how to diagnose them.
Engine and transmission vibration
Excessive vibration from the engine and transmission mounts is one of the most common signs of transmission mount failure. This is because the mount stabilizes the engine driveshaft. So when the mount breaks, the driveshaft loses its stability and starts to vibrate. The vibration often decreases when the vehicle is set to neutral and increases at higher engine speeds. If you notice such vibration in your car, have the transmission mounts checked and replaced if necessary.
Loud thumping noises
Another common sign of transmission mount failure is a loud thumping noise, particularly when accelerating or braking. Many Jeep Cherokee owners describe the sound as similar to that of a snowball or a heavy clump of dirt hitting the undercarriage. In such cases, the transmission mount has softened due to wear and can no longer hold the transmission securely in place. This, in turn, causes the engine to lift up when the vehicle accelerates and slam down when the throttle is released, creating the thumping noise.
A loose, worn, or misaligned transmission mount may also change the alignment of the transmission, resulting with an ill-fitting link between the transmission and the driveshaft that can damage both the driveshaft and transmission coupling.
Cracked transmission housing
Worn or damaged transmission mounts will not be able to support the transmission and eventually buckle under the weight. Once this happens, the strain of the unsupported transmission weight will cause the transmission housing to warp or crack. The internal components of the transmission are also likely to get damaged if more than one transmission mount fails.
