There is a knocking sound coming from the tire on the drivers side. on 1997 Chevrolet Monte Carlo

I had someone look at it because I thought it might be the bearings , or the tire rods, or the struts. The mechanic said that all of those things were fine. What could be making that knocking sound when I drive, make a turn, or hit a bump?

lightly step on brake and see if noise goes away.may have worn caliper hardware or loose pads.
could be a strut mount or a bad tire
