Car shaking when accelerating >30mph. Bad strut/tire?

There are several possible causes for a car shaking when accelerating, including:

* Driveline issues: This could include problems with the driveshaft, universal joints, or transmission.

* Tire issues: This could include problems with the tires themselves, such as uneven wear or a damaged sidewall, or with the wheel alignment.

* Suspension issues: This could include problems with the shocks, struts, or control arms.

* Engine issues: This could include problems with the spark plugs, ignition coils, or fuel injectors.

If your car is shaking when accelerating, it is important to have it inspected by a qualified mechanic to diagnose the cause and determine the appropriate repairs.

Here are some additional tips for diagnosing and fixing a car that is shaking when accelerating:

* Check the tires: Make sure the tires are properly inflated and have even wear. If the tires are worn or damaged, they can cause the car to shake.

* Check the wheel alignment: If the wheels are not properly aligned, this can also cause the car to shake.

* Check the driveshaft: The driveshaft is responsible for transferring power from the transmission to the wheels. If the driveshaft is damaged or worn, it can cause the car to shake.

* Check the universal joints: The universal joints are located at the ends of the driveshaft and allow it to move up and down. If the universal joints are worn or damaged, this can also cause the car to shake.

* Check the transmission: If the transmission is not working properly, this can also cause the car to shake.

* Check the engine: If the engine is not running properly, this can also cause the car to shake.

If you are unable to diagnose and fix the problem yourself, it is important to have your car inspected by a qualified mechanic.
