2. Bad Engine And Transmission Mounts

The engine mounts of the car are responsible for holding the whole weight of the engine and transmission upon the car. They also act as a buffer that absorbs all the vibrations and sounds that the engine emits during the operation. When the engine is started the first time,  it shakes heavily in the place, and the engine mounts health to absorb the extra vibration. If the engine mounts are failing, then they would transmit all the starting vibrations directly into the body creating a sound.

Solutions For Bad Engine Mounts

When the engine mounts have gone dad, you don’t have much choice other than to replace them with a new unit. Since they are made of rubber material for hydraulic based, it is almost impossible to get them repaired or rebuilt. In the case of German cars, you have to sometimes get the whole engine out of the car just to replace the engine mounts. 

3. A Weak Car Battery

Starter noise during cranking can also be caused due to a very weak battery. When we use the starter motor the first time, then it consumes a very large amount of current in excess of 600 amps. The car battery that, as the reservoir frot the starter motor. It provides those juicy amps to the starter Motor.

Due to prolonged usage and age the car gathers, it is very common for the Bendix to wear out and start slipping.
