front end grinding on slow turn HELP!!!

hey guys i need help !!!
i just got a 94 GT, never hit, all stock and all of a sudden when im moving slow and i turn the wheel i occasionaly feel a grinding in the front and once this happens for a minutes i would feel it even if i just turn the wheel side to side slightly even while standing
im confused as it doesnt happen when the car is cold only after i drive it for some time and then i would start to feel that mellow grinding - not only in the wheel but in my seat - although my wheel turns completely normal and then it would go away and come back again but only when im turning slow slow
any ideas please !!!
thanks

ye i do get it only after the car is warm or when its hot out
n ye only makes the noise while driving really slow like in parking not in actual driving
could it be my tie-rods (a b.s. mechanic told me thats most likely the cause)???
*btw how crucial is it for me to do this right away altho i dont want any further damage?

thank you guys !
