How to diagnosis the front engine mount?

While you're waiting for a tech to give you a more detailed answer, I'll contribute thsi: if the engine mounts are original, you can pretty much count on them all being worn out. This is a known issue with this series Camry. If the mounts have been replaced, check to see if the radiator hoses have stiffened with age - they can transmit too much vibration when they get hard.

try this-when you turn hard does the power get weird... Those were the symptoms on my wives camry and it was the engine mounts..When you would turn hard--you would lose some power..

The engine needs to be raised slightly to take the weight off the mounts. Typically a block of wood between a floor jack and the oil pan is what the shade tree mechanic uses.

Check the front and rear mounts then for cracks, hardening, and separation. Replace as necessary. Some people shift from neutral to drive/reverse and look for excessive engine movement. Also check the transmission mount.

In addition to engine mounts, also check the harmonic balancer pulley. The rubber may have deterioated. Of course we assume the engine is well tuned and working properly, etc.
