Here Are Some Reasons If your car starts shaking or shuddering when you start driving or suddenly starts doing it while you are driving e.

If your car vibrates while idling, braking, or accelerating, it signals something is wrong. What causes a car to shake when driving?
Another possibility is that you have a bent axle. Your best bet is to resolve any shaking issues before they worsen. This will allow you to take the proper course of action should they show up. But even if you drive less, you still have to worry about the tires themselves becoming old and drying out. This is known as dry rot, which causes them to become brittle, lose color, and start to crack. Otherwise, you are putting yourself and those around in danger by continuing to drive on them.
Fixed over the rotor, is a brake caliper, which squeezes the brake pads against it, creating friction and slowing the rotation. Over time, the rotor can become bent or warped. When this happens, and the calipers squeeze against them, you may notice a vibration. Thankfully, rotors last a while, usually between 30, to 70, miles.
Basically, any issue that involves your brakes should not be ignored. Warped rotors can not only reduce braking performance, but they can also make it hard to control your car in an emergency situation. You May Have Engine Issues There are several components under the hood of your car that can cause it to vibrate while idling or accelerating. If any of them are worn, it can interfere with them firing correctly. When an engine misfires, it can cause a shake with each cycle.
This can also cause a misfire, and thus a shake. You might also have worn motor mounts. Thankfully, they usually last for between years. Beyond this, they may weaken, which might lead to a noticeable vibration. The good news is that spark plugs and fuel or air filters are cheap to replace. Wheels Are Damaged Or Need Balancing If your car shakes while driving, it may just mean you need your wheels balanced.
Balancing is the process of distributing weight evenly across the tire and wheel assembly. This ensures that they rotate correctly at higher speeds. Even a small weight difference from one wheel to the next can cause your car to shake. They place it on a machine that spins it at a high rate of speed and then measure the weight around the circumference. The tech will then attach weights around the wheel to ensure it is perfectly balanced. Damage to your wheels can also cause your car to vibrate.
This usually stems from running over an object or a pothole. Thankfully, unless the damage is severe, a shop should be able to restore it to its original shape. A Bent Axle May Be At Fault If your car started shaking after an accident, or some other mishap like running over a large pothole or hitting a curb, you might have bent an axle. If you do not know already, an axle delivers power directly from the transmission to the wheel.
It is basically a shaft connecting these two parts, that rotates with the wheels. It all depends on the extent of the damage and whether a repair is even possible. The make and model of your car also influence the cost. Otherwise, you may wreak havoc on the rest of your suspension system, which can become expensive rather quickly.
If the shake is minor, you should be ok driving for at least a little while. When was the last time you replaced your tires, spark plugs, or filters? How about balancing your wheels? Have you recently run over a large pothole? Related Reads.
