Hi folks

I have 2005 Toyota Camry XV30, 2.4 ltr, which i bought recently, the problem i am facing is whenever i start the car engine either in idle or when i am driving car, i feel an vibration/humming in whole of the dashboard and steering, this humming / vibration increases when i press the accelerator, irrespective of either i am driving or when the car is parked, i had it checked from the mechanic, he has changed all the engine mounts but still problem continues. The only way this humming / vibration goes is when the mechanic lifts the car with a jack and at one specific elevation car becomes smoothe as silk. Any advice plz? Going crazy with this. Appreciate it, regards

 

Anyone plz?

 

When the car is jacked, is it the front that he is jacking or the whole car? I am just wondering if the front is just jacked up, then the vibration goes away.
