- Wheel balance: Even if the tires are new, improper wheel balancing can cause shaking at high speeds.
- Transmission problems: Issues with the transmission, such as worn-out gears or a faulty torque converter, can also lead to vibrations.
- Engine issues: Engine problems like misfires or a faulty ignition system can cause the car to shake during acceleration.
- Aerodynamic issues: In some cases, aerodynamic problems, such as turbulence caused by aftermarket modifications, can cause the car to shake at high speeds.
It's important to have the vehicle diagnosed by a qualified mechanic to accurately identify and rectify the cause of the shaking during acceleration at high speeds.
