2004 Chevy Impala suspension/steering

hey guys
I have a 2004 chevy impala w/ 63800miles
i take good care of it but
i seem to be having a problem with
my front suspension/steering . It feels wobblely
espacially when i make a turn on to another intersection at speeds of about 15-20mph thru bumpy roads. It sounds like something
is loose or worn. what do you guys think it could be
rack and pinion, tie rods?

thanks ,johnny
