Could alignment work bring in clunking noise?

Done my control arm and tie rod end replacement yesterday.
after that I immediately drove to a alignment shop and done the alignment.

while I was driving to there, there's no clunking IIRC

Today when I drove the car I found there's clunking in the front when have small bumps on the road.


my question is, is it because some loose nuts/bolts (maybe because when I tighten them, the car is not loaded)
or it might be caused by the guy doing the alignment?

(I have a camber plate, and he adjust it by loosen the three bolts holding the strut mount to the chasis, and smack the top )

Where could I check?

another thing I could think of is, when I put on the control arm, I tightened the bushing bracket first, and then the ball joints. I don't know if this is a wrong sequence and don't know if this could cause loose nuts when the car is loaded.

Check the lock nut on the tie rod. Maybe they didn't tighten it.

a loose nut would make the car wonder and loose alignment. not necessarily a clunking noise.

Could be a loose nut or something. You should go back to the alignment shop and let the person who performed the alignment know that you are now experiencing some clunking/noises that weren't present before the alignment, so you want to double check to make sure everything that was adjusted is to the proper torque specs.

Bam. 9/10 this is it. For some reason these often need to be tightened twice. Once. And then once again after like 50-100 miles.
Hope this helps.

Hmmm is that a common issue? I just changed the front sway bar links right before thanksgiving. Tonight I'm hearing knocking noise in the front left. I was thinking swaybar links also. I was shaking my head saying I just changed these???

+1 on the links - tighten them with suspension loaded on ramps. I've experienced that issue - it's LOUD and vibrates tremendously.
