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.
Misaligned transmission
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.
The transmission mount of the Jeep Cherokee is designed to be as rugged as the vehicle itself, but it still needs proper maintenance from time to time in order for it to provide sufficient performance for a long time. As with other parts of your Cherokee, the transmission mount is quite vulnerable to wear and damage. But with proper use and maintenance, the Jeep Cherokee transmission mount can provide years of service without fuss.
Inspect the mounts on a regular basis
Some of the things you need to look out for include cracks, loose brackets and missing bolts. Check the rubber portion of the mount as well for rot and brittleness. In addition, check for unusual thumping noises when the engine is running. Worn or damaged transmission mounts would not be able to secure the transmission properly, resulting in thumping noises particularly when the gas pedal is applied. Replace any worn and damaged transmission mounts as soon as possible.
Avoid driving aggressively
While the Jeep Cherokee is designed for tough driving conditions, consistently aggressive driving practices can stress out the transmission mounts. Every time the Cherokee is put into gear or the gas pedal is depressed, the torque from the engine moves both the transmission and motor mounts. And by driving aggressively, the stress imposed on the mounts is greater compared to normal driving. This will eventually cause the mounts to break apart even if they are still far from the end of their service life. So don't drive aggressively if it can be avoided; the transmission mounts will thank you for it.
Keep the mounts protected with silicone lubricant
The rubber parts of the transmission mount are vulnerable to dry rot, wherein the rubber starts to become brittle from heat and age. Transmission mounts will eventually succumb to dry rot, but this can be kept at bay by covering the mount with silicon-based lubricant. Silicone helps prevent the rubber parts of the mount from drying out and, thanks to is inert and non-flammable properties, suitable for use near the engine. We recommend using spray-on silicone lubricant as they are more convenient to apply than silicone grease.
