Hello new here. I hope for the love of God someone can help me. I have a 05 Sebring convertible that has a hard clunk over bumps at all speeds. So far we have replaced both lower control arms due to bad bushings, both strut assemblies including new mounts and upper control arms, sway bar links. Checked tightness on every bolt I could reach including frame to body bolts. I'm at a loss because everything seems tight yet it still has a noise from what sounds like the left front. Any help would be appreciated.

 

Engine mount? Just a guess.

 

How certain are you the clunk is coming from the front? One known area is the rear upper strut mount. They tend to disintegrate and unless yours have been changed could be a likely candidate.

One area in the front are are the sway bar bushings; the bolts can be tight but the bushings may be worn or gone.

 

I'm pretty sure it's front. Been at my shop driving it around and when I pull in as soon as the front tires hit the threshold it clunks.

 

My Sebring had a persistent clunk in front until I replaced the upper ball joints. But it seems like you've ruled that out by replacing the upper arms.
