It is Accord 98 I4 LX.
When I shake a steering wheel there is a knocking-cklicking sound comes from rack and pinion. Should I replace it or it worth to fix it?

Also, I need to replace left front swaybar end link. Do I need some special tool
to take of a lower nut or I'm missing something?

I would like to check all this before I take my car to the dealer.
Thank you!
