Popping sound on drivers side

Had a broke sway bar last year an it got fixed, then the popping sound started. I was told it was the shocks and struts, had that replaced on both sides in front this year recently. Well that seemed to solve the rough riding we was having and the popping stopped on the highway. We could never go above sixty miles the car would pop and shake. But now it is still popping, but not as bad just do not know what is causing it whether it is serious or not.
