Getting inner tie rods replaced tommarow! what should I expect?

I am getting my inner tie rods replaced on my 91 olds 88 royale tommarow. for about 2 years I have had a strange rattling sound around the middle front of the car whenever I had to go slow on the dirt road to my house or on any dirt road. so when I get these tie rods replaced, what should I expect for improvements after its all said and done? I know nothing about these things so any help would be great!!

thanks
