What are the causes of body vibration when the vehicle speed is between 60 and 80?

[DelNorah]

When the vehicle speed is between 60 and 80, the causes of body vibration are as follows: 1. It is caused by the aging or damage of the engine or transmission mount pads. Replacement can eliminate the issue. 2. Damage to the chassis half-shaft or drive shaft; this mostly occurs during acceleration or deceleration conditions. 3. The tire and rim require dynamic balancing, or the tire may be aging and deformed, or the rim may be deformed. Perform tire dynamic balancing as needed to check the condition of the tire and rim. When the car accelerates from 60 mph to 80 mph, the front body vibrates, but it does not vibrate when the accelerator is not pressed, nor does it vibrate at other speeds. This is caused by excessive clearance in the front suspension ball joint or connecting components, which creates vibration at a certain frequency. It is necessary to go to a repair shop to adjust the toe-in and front wheel alignment.
