There are two types of squeal: one is a high-pitched shriek and the other is a low-pitched growl. A high-pitched shriek occurs during normal braking. It also occurs during light braking on vehicles with Read more Brake Squeal Phenomenon and Causes
Causes
Vibration During Braking Phenomenon and Causes
The dashboard, steering wheel, and seats vibrate abruptly upon braking. A pulsation is felt on the brake pedal at the same frequency as this vibration. Although the frequency is similar to that of body Read more Vibration During Braking Phenomenon and Causes
Cranking Vibration Phenomenon and Causes
The body and seats shake slowly when you are cranking the engine. This vibration occurs immediately upon cranking, and stops the moment the engine has started.
Main causes
Engine torque fluctuations
Body Read more Cranking Vibration Phenomenon and Causes
Take-off Vibration (Acceleration Vibration) Symptoms And Malfunction Causes
Mechanism
1.Engine torque fluctuations
On take-off, the engine rpm drops when the clutch is engaged. At this time the engine torque fluctuations increase, causing the engine to vibrate on its roll Read more Take-off Vibration (Acceleration Vibration) Symptoms And Malfunction Causes
Take-off Vibration Symptoms And Malfunction Causes
The body, instrument panel, and steering wheel vibrate slightly on take-off. This occurs during gradual engagement of the clutch, while the engine is still idling. The shift lever, front seats, body, and Read more Take-off Vibration Symptoms And Malfunction Causes
Clutch-shudder (Judder) Symptoms And Malfunction Causes
This symptom occurs when the clutch is engaged at take-off, shaking the vehicle in fore- and-aft direction. The shaking stops once the clutch has been completely engaged. It occurs more often when the Read more Clutch-shudder (Judder) Symptoms And Malfunction Causes
Wind Noise Symptoms And Malfunction Causes
This noise can be heard as airflow hissing in the window area. It occurs mostly at high speeds, and changes in the vehicle speed or in the direction of the wind alter this noise. Usually the volume of Read more Wind Noise Symptoms And Malfunction Causes
Engine Noise Symptoms And Malfunction Causes
A relatively high-pitched noise is whining in the passenger compartment, increasing in volume with increases in engine rpm, when the vehicle is running at high speeds or under a heavy load.

Body Beating Noise Symptoms And Malfunction Causes2
1.Torque converter slippage
(1)Noise caused by imbalance
If there is an imbalance in the pump impeller, and another behind the turbine runner, such as in the propeller shaft, each one of these components Read more Body Beating Noise Symptoms And Malfunction Causes2
Body Beating Noise Symptoms And Malfunction Causes
The volume (amplitude) of this noise alters cyclically, coming to you in waves. The frequency of the noise accelerates with the increase in vehicle speed. This noise occurs at certain engine and/or vehicle Read more Body Beating Noise Symptoms And Malfunction Causes
