if it shakes while your braking your front roters could be warped or if it shakes while your driving try balancing the tires at a tire shop.
if the steering wheel shakes there can be a problem with alignment. shaking when braking would probably be a brake problem. constant shaking i'd expect you should check the muffler If the front end of your car shakes when just driving normally, your front end probably needs re-aligning. If it shakes when you apply the brakes only, your brake rotors are probably warped and need re-surfaceing. Impossible to answer question, please be more specific. It shakes when... I feel it shake in the steering wheel when... I'm driving along and... etc. It depends on WHEN it shakes. Low speed driving: damaged tire, U-Joint, ignition misfire, burned valve, low engine RPM. Highway driving: loose steering, faulty ball joints, tire balance, bent wheel, tire damage. Engine idle: burned valve, ignition misfire, motor mounts, low engine RPM, dirty injectors, EGR valve... All of the above plus quite a few other possibilities.
because ur hand is shaking
It is normal chihuahuas usually shakes and it could be hot.
Does it quit shaking when it warms up? What engine and year of Aerostar?
AnswerMore likely...if it shakes from side to side while driving I would strongly suspect a frozen upper or lower link in the rear suspension. Alignment issues will cause vibration but not side to side shaking.
engine rubber mounts or timin out
If the motor is shaking in your Kia Sephia, you probably have loose motor mounts. Simply tightening these up will stop the engine from shaking and vibrating.
you need a front end alignment
The intensity of ground shaking during an earthquake is influenced by factors such as the earthquake's magnitude, depth, and distance from the epicenter. The type of soil and rock formations in the affected area can also impact the extent of ground shaking. Additionally, local topography and buildings' proximity to fault lines can amplify shaking.
Need more info like what is the vehicle doing when it shakes, is it idling in park, driving down the road, braking, driving at highway speeds, etc.
If your car is shaking, it normally has to do with your tires. Check your tires for a flat or to make sure they are securely put on.
