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.

Why do you have camber plates?

Sway bar end links.

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.
