Your Mercedes-Benz has a part called a motor mount which is part and parcel of the smooth-driving experience you’ve come to expect from your vehicle. Composed of metal and rubber, the motor mount is there inside the subframe to hold up your transmission and engine.
Naturally, it can wear down over time, and that’s when you’re going to start noticing that your drives are a lot less smooth, as bumps in the road and your engine’s operation become more apparent with increased vibration and other symptoms.
Thankfully, this is something that you can watch for if you know the signs, or even eliminate completely with a little preventative maintenance. Today we’ll talk about some symptoms to watch out for that may indicate your motor mount needs to be replaced, so that you’ll know what to look for and when it’s time to get your Mercedes into the shop!
Signs your Mercedes motor mount needs replacing
There are a handful of signs and symptoms that will pop up when your motor mount is starting to wear out.
Mercedes ‘ignition lurches’
If you start up your Mercedes and find it lurching forward lately, and also repeating this behavior when you cut off the ignition, then this could be related to the motor mount. Sometimes when it loses firmness, the torque of the engine causes it to move around a bit in the housing.
After a while this becomes a heavy vibration, rather than lurching, as the problem becomes more advanced. If you are experiencing this, then it’s a good idea to get your Mercedes looked at right away before the problem can become worse.
Changes in vibration
Aside from securing your motor and transmission in place, a big part of the motor mount’s job is to absorb vibrations from engine operation so that your drives are smooth and pleasant. As such, one of the first signs that the motor mount may be degrading is going to be excessive vibration.
You can also end up with leakage from fluid-filled mounts, so you may see a puddle underneath your vehicle as another warning sign that the mount may be compromised. In any case, the excess vibration means that it’s time to get a closer look at the motor mount as soon as possible.
Clunking from the engine
Another common symptom that the motor mount may be degraded or otherwise damaged is the sound of knocking or clunking from the motor bay. While it may just sound annoying and not seem to do much of anything else, you want to keep in mind that the engine is no longer firmly fixed and that movement may result in damage to other components!
Mercedes vehicles are famous for the way they seem to glide smoothly over the road, so any noises or knocking from the engine bay should be addressed immediately – before they can become more costly problems down the line!
Gear jolts while driving
If you are noticing sudden ‘jumps’ when shifting beyond the expected change of pace, but only when your Mercedes is moving swiftly down the road, then this could be an indicator that the motor mount needs replacing.
You may also notice thudding or knocking when this occurs and that’s definitely not a good thing – it could be the engine moving about, and potentially lead to engine block damage or worse.
You’ll want to get your Mercedes in immediately to someone who knows their way around these vehicles, such as Motorhaus of West Palm Beach, FL.
