Actually, any number of things.
1) Could be a tire out of balance
2) You may need an alignment
3) or you could need some other front end work such as ball joints. If your tires are good and your alignment is good then take the car to a mechanic to see what is wrong.
Wheels are not balanced or ball joints
its chasis could be loose or its just old chasis being he thing that holds the wheels to the car.
As I remember ^^ Because once you start the engine you give it power so it start working, and this power is really so HIGH that your car can start from 0 MPH to 100 MPH or something like this. So for sure it would shake.
Could be tires out of balance. Or a bad tire.
Especially if it does it for 5-10 mph at starting at a certain speed, it is almost always wheel balance only. If it persists, check for alignment and bent wheels.
My steering wheel shakes what could this mean? _____ try getting your car re-aligned.
yes, it does. Once the outer tie rod is loose or damage the wheel automatically lose strength and start shaking.
your problem is yu have a broken motor mount that will make the car shake when you start it and step on it
Yes
A car may shake at 45 to 55 mph due to several potential issues, such as unbalanced tires, misaligned wheels, or worn suspension components. Imbalances in the tires can cause vibrations that become noticeable at specific speeds. Additionally, problems with the drivetrain or brake components could also contribute to the shaking. It's important to have the vehicle inspected to identify and resolve the underlying cause.
Yes, one bad cell in a car battery will cause the car not to start.
Certainly, a loose wire on the car battery can cause the car not to start.
