Need some help with a steering knocking and wanna change the clutch myself but need a few pointers.

I have a 2005 relay 2.2. And over the last few months the steering has developed a knocking especially when going from lock to lock at slow speed. I believe it to be the bearings on the strut tops which I have bought. Am I on the right track and how much of a job is it for a DIYer?
