Did the problem exist before replacing the engine mount? If not, maybe the mount was incorrectly or poorly installed.

Could be a transmission mount or maybe an engine vibration damper.

no when i put on the motor mount i done it the perfectly way.... but i forgot to check my trany mount to see if it is bad... the problem started a year later when i but on my motor mount... i might think that i has to be my trany mount because my i can feel the rattle on my shifter... o yea and when the problem just started i drove foe about a week my driveshaft bolts brakes off... i dont knoe why how can it break.... if you think that it might be my trany mount then what brand should i get and would it be expensive....
