Your shock absorbers are the primary suspension components that actually help “absorb shock” preventing continued bounce every time you accelerate, stop, corner or hit a bump.
One of the most common problems that can cause a car to shake when slowing down is unbalanced tires. An unbalanced tire will lead to uneven tread wear, premature tire aging, and extra friction from the wheel itself. This imbalance often causes this shaking sensation and vibration in the steering wheel.
Why is my front end bouncing?
Here are some of the common reasons why your car may be bouncing excessively or swaying: Your wheel alignment is bad. Your tires have excessive or uneven wear. You have a loose steering linkage.
Worn-out spark plugs or the electrical cables attached to them are one of the most common causes of cars stuttering. A deficient spark plug causes the engine to misfire, making your car jerk when you accelerate.

Why does my car shake when slowing down from high speed?
Your car’s front-end alignment could be way out of whack. Your car’s steering might suffer from a loose control arm or damaged knuckle. You might have a damaged axle shaft that’s acting up. You might even have a case of loose lug nuts, giving the wheel a chance to wobble that becomes especially noticeable as you slow
What does it mean when your car jerks while braking?
If the brake rotors are out of balance or warped, the vehicle can jerk to a stop or rapidly vibrate depending on your driving conditions. If the brake pads are worn or filled with dirt and debris, the area of the rotor under the brake pads can collect these substances, causing the car to pulsate when braking.
Why does my car jerk when I downshift?
With a manual transmission it jerks when you downshift because in the higher gear, your engine was running somewhat slowly. When you downshift you need to either slow down the car or speed up the engine (or both). The jerking is when your slow engine slows the car and your fast car speeding up the engine.
The transmission control module controls the shifting as you accelerate, so you may experience delays with shifting, which can cause your car to jerk. While this is not as common of an issue as others in this list, it can certainly be the culprit behind your car jerking.

What causes a car to surge while driving?
Usually, there are three leading causes behind car surging when accelerating. First, it can be that your fuel is making its way to your engine correctly. Second, it can be due to faulty torque converters. Lastly, engine misfires can come from a loss of vacuum coming from the intake system.
Can a transmission cause surging?
Surges or Stalls
Surges and stalls can mean you have a serious transmission problem. Normally your car should move as soon as you put it into gear. Not only are these symptoms of a transmission problem but surging and stalling can be extremely hazardous while driving.
Engine surging is usually a warning sign that your car or truck is having combustion problems. Since a vehicle’s ignition wires and spark plugs play a major role in proper engine performance, it is likely time to check your engine’s electrical components.
Can bad spark plugs cause surging?
Surging and Lagging
Another good indication that your spark plugs are dirty or worn is if your vehicle experiences surges of speed, resulting in a jerking acceleration. These surges occur because your spark plugs are not igniting the fuel in your engine at the proper rate, resulting in an uneven speed.

What is engine surge or hesitation?
Hesitation is when your engine misfires, stumbles or lacks power when you accelerate or step on the throttle.

What causes a small engine to surge up and down?
A dirty or gummed up carburetor causes an engine to surge. If you feel comfortable working on carburetors, unbolt the bowl and clean it thoroughly. Check whether the float moves up and down without sticking, and clean the tiny ports on the bowl hold-down bolt.
