Vibration in Car

When you own a car in a long run there is a good chance that it might have developed some mechanical problems and the most common is vibration or shaking of car. This problem starts gradually and develops to a level that vehicle shakes, shimmies or vibrates out of the ordinary. The fix could be something relatively cheap like wheel alignment and balancing or it could be more serious and costly like steering or suspension issues. Diagnosing a car trouble on the basis of symptoms at early stage is always better as it could save you from big repairing bills.
As a part of experience with my car, I have figured out top 5 reasons for vibration in car. These include:
1.Tire Problems:

a. If the car vibrates at certain speeds then tire requires wheel balancing.

b. If the tires have separated tread then tire requires replacement.

c. If your vehicle tires have uneven tire wear then it requires tire rotation.

d. If the tires are out of round and rolls unevenly then tire requires replacement.

2. Wobbly Wheels: While driving if you feel your car vibrate directly through the steering then it's a logical thing to guess alignment issue might be the reason but car experts indicates other possibilities too.

a. One or more wheels have excessive play or wobbliness at the hub itself. Make sure each wheel is fastened securely to its hub with properly torqued lug nuts.

b. Wheel bearing need replacement. Although in modern vehicles wheel bearings are meant to last the life of car but if your vehicle subject to extreme hard driving or off-roading then bearing wear out could be the reason.

c. Another reason of wiggling, wobbly wheels include the tie-rod ends or ball joints. If they're worn out, they'll allow too much play in the wheel which leads to vibration while driving at speed. While driving avoid potholes in the roads and slop road repairs.

3.Brake Issue: In the vibration appears or intensify on application of brakes then twisted or out of shape brake rotor could be the reason. The rotor can get bent out of shape due to overheating from more stopping than that particular rotor can handle. As a result the brake pads squeeze the brake rotors to stop the car can't get the even grip on warped rotor and hence vibration.

4. Axle Issue: Our vehicles are full of reciprocating rotating parts which needs to fall under certain measurements or tolerances in order to perform properly. In case of collision there are chances that axle gets bent. With this problem the vibration often intensify the faster you drive which even causes the shaking of vehicle. Then driveshaft also needs inspection.

Another related reason could be Worn-out constant velocity (CV) joints. If the "boots", those rubbers, accordion-like coverings around the ends of the drive axles are torn and lubricant is seeping out then your vehicle need drive axle replacement.

5.Engine Issue: Sometimes vibration generating from engine compartment might be a sign of engine trouble because the engine isn't getting enough air, fuel or spark that it needs to run smoothly. These symptom includes:

a. Shudder or jerking occurs during acceleration.

b. Staccato shaking, as if over a highway "rumble strip," within a specific speed range.

c. Car starts and drives fine for a while, but later begins to shake. These all symptoms indicates the replacement for spark plugs or the spark plug wires need to be checked it they are connected properly.

Another engine related problem could be a dirty air filter or clogged fuel filter can starve the engine of needed oxygen or fuel. So be sure to replace them at the manufacturer's recommended intervals during the vehicle service schedule.
