Why does my Jeep shake when I turn on AC?
When the AC is turned on, the mountings undergo additional strain due to immense starting load. So any issue in the mounts will result in shakes or vibrations. The broken mount can lead to increased vibration and noises especially when the compressor of AC puts pressure on the engine.
How is intermittent vibration related to exposure time?
Intermittent vibration is assessed using the vibration dose concept which relates vibration magnitude to exposure time. Relevant multiplying factors are used to derive acceptable magnitudes of vibration on the basis of the receiver type and the nature of the vibration.
Is it normal for a car to vibrate when idle?
The car vibrates while idle in drive, lower gears, and reverse. However, when it is in Neutral, the vibration is at a normal level. In Drive, once we accelerate, vibration is normal.
Which is the best way to assess intermittent vibration?
Section 2provides preferred and maximum values for continuous, impulsive and intermittent vibration. Intermittent vibration is assessed using the vibration dose concept which relates vibration magnitude to exposure time.
What is the current technical guideline for vibration?
Evaluation of human exposure to vibration in buildings(1–80 Hz). BS 6472 (current and former versions) has guided the Department of Environment and Conservation’s (DEC) evaluation of vibration since the mid-1980s. Thus, this technical guideline does not represent a change in policy approach.
Why does my Jeep Grand Cherokee have vibration?

When i brought it to the dealership they said the drive shaft was to blame and they replaced the drive shaft. drove home and noticed the same problem once again.
What causes vibration in the CV joint when accelerating?
Damaged Inner CV Joints Can Cause Vibration on Acceleration. Damaged inner CV joints cause vibrations on acceleration and are very difficult to diagnose because the damage is so inconspicuous. You can only see it once the inner CV joint is removed from the vehicle and cleaned of all grease and debris.
Is the vibration on a Jeep Commander bad?
The vibration doesn’t sound as bad as yours — my seat doesn’t move — but it is annoying and makes the feel of driving the car very unpleasant. Everytime you step on the gas, if rumbles and vibrates. I have it too on my Commander with the HEMI. At around 70 it kicks in. Annoying as hell.
Why does my Corvette have a vibration in it?
Figuring out what’s causing that vibration is the real challenge. It’s a good idea to start with the basic, tire-related culprits such as tire wear, pressure and balance. That said, there are a few issues unique to the Corvette that require special care and attention.
