And this is definitely the most common cause of vibration complaints. But what do you do when you put on new tires and they balance out perfectly yet the vibration continues to exist on the vehicle. If the car is a front wheel drive automobile checking out the CV joints and the drive axles would seem to be the next logical step.
If it is a rear wheel drive automobile universal joints and drive shafts should be inspected for problems. Often these different types of driveshaft components can create car vibrations that feel very much like tire balance issues.

While inspecting the CV joint for problems such as ripped boots or loose clamps it is also a good idea to check the transmission and engine mounts at the same time. Any of the above mentioned parts that are broken or defective can cause vibrations under load that may feel like a tire or wheel balance problem.
A good rule of thumb to apply if you have car vibrations at highway speeds is that a wheel balance problem will be continuous regardless of your throttle position. Vibrations from the CV joint would be worse under power and may disappear completely when your foot is taken off the accelerator.
This same rule of thumb would apply to a rear wheel drive vehicles using a driveshaft with standard U-joints. When these parts develop excessive clearances vibrations are usually more evident when the loose parts are under load and can disappear when the vehicle is coasting.
