2001 Hyundai Elantra Clanking noise went I hit small bumps

I just replaced the passenger side CV boot on my Elantra (the boot had torn) prior to replacing it no noise was detected, I had to removed the entire assembly cleaned out the inner housing and bearings as well as the outer one, repacked sealed and reinstalled but as I test drove I heard clanking noises comming from the same side (had not noticed before). I noise only happens when I hit small bumps on the road, what do you think could be the problem.
