Weird sound while turning

I bought my 97 SH about 6 months ago and have been fixing things ever since. The newest problem is that whenever I turn Right the car makes a really weird creaking noise. But it only does it when I turn Right. Could it be the steering arm boots? I took a look at them and they are both pretty cracked. I checked in the Haynes manual and couldn’t find much about it. Anybody have any idea? And if it is the steering arm boots how hard are they to replace? Thanks in advance for all your input
