You may have bad motor mounts. I would check this 1st.

SOURCE: I have front end vibration

just checked this out a while ago:



Wheel Hub Assemblies: Systems and Diagnosis of Worn Hub Assemblies & Bearings
Front wheel hub assemblies and bearings control the position of, and reduce the resistance of, vehicle wheels in contact with the pavement. When they fail, front wheels may not be kept in position and vibration and noise usually develop. Symptoms that normally develop as a result of these worn parts include:

• A humming, rumbling or growling noise which increases with acceleration or as the vehicles turns
• Vibration felt in the steering wheel, which changes with vehicle speed or as the vehicle turns
• Looseness or excessive play in the steering wheel (especially while driving over rough road surfaces)
• A loud, constant grinding noise when driving the vehicle (heard in the most severe cases of a wheel bearing failure)
• Pulling to one side when braking.
• Roughness - with the vehicle of the ground, roughness or vibration when rotating the wheel
• Looseness - with the vehicle off the ground, looseness when wiggling the wheel back and forth (Looseness may also indicate a worn ball joint)
• Excessive brake pedal play can also indicate sloppy or excessively loose wheel bearings
• ABS failure in the system may be related to failure of the ABS sensor in the hub assembly or the internal sensor in the wheel bearing

check badly worn frt tire,bent wheel rim,loose wheel rim,frt tires may need te be rebalance

SOURCE: steering wheel shakes and brakes vibrate badly when stoping

Sounds like the rotors are warped,Take to a brake shop and have them checked or replaced.

i had the same problem in a 2001 avalon. i had the brakes machined and the problem was solved.
