Loose steering?

i have a 2000 cavalier Z24 with about 110K on it. so far its been great however ive noticed an increase in movement in my steering wheel at high speeds(high speeds meaning 70-75mph) its not too bad but it could be dangerous to someone whos not used to it on a wet road. i know i need to get my power steering fluid changed and i plan on it next week but i dont think that is the problem. any input would be appreciated, thank you.

New fluid would help, although things can be warn and you can adjust you pump to be stiffer steering.

thanks for the info, i didnt realize that you could adjust the power steering pump?
