Chevy s10 bad steering problem

I just bought a 2000 s10 extended cab 2wd. I have been driving it for about 3 weeks now everything seemed fine then it started making a knocking noise sounds like it’s coming from the driver side suspension area (not motet Knocking) I hear it when I hit bumps in the road but it’s gotten worse now ver the last week or so. The steering was tight when I first started driving it now it seems to have gotten lose. Also pulls to the right pretty bad .Yesterday while driving home from work it about half way home it got really bad. The best way I can describe It felt like the wheels were going to fall off going 60 mph it was hard to keep it straight The knocking noise was worse as well. Any ideas I jacked it up and looked under it but did not see anything broke. Anyone else ever have this problem I have no idea what to do or where to start.
