Noise from underneath front end?

So, I just changed out my front strut assemblies, sway bar links and lower control arms which of he 3 were the most difficult to get off and then back on but after I test drove it I began hearing a rattle or knockin those areas mostly soundong like from the passenger side area as if a bolt had come loose or even out. When doing the driverside the axle didnt move in and out at all and getting the new control arm was beyond difficult but was done finally. I jacked back up on the passenger side where I felt the noise was coming from and didnt see any lost or coming loose bolts and nuts but still could I have not tightened them tight enough on the arms or to much on the struts or links maybe or could it be that driverside axle is bad I just bought it and no very little about it.
