Over the years I've skimmed hundreds of individual responses in control arm threads here, but not sure I recall reading anyone who points out what you should look for to determine if your control arms are bad. Is it a noticeable change in ride quality? Something else?

In my case, I had one ball joint and one control arm that were bad. The only way I found out, was when I went to have a wheel alignment done. The tech discovered the problem and said they couldn't do the alignment until I had them replaced. The car drove fine.

in my case, the LS460 would make a noticeable clunk sound when applying brakes moderately hard at ~40mph.

Clicking over speed-bumps is a good indicator. Then you can also use my fave: the rubber mallot method. Whack those control arms and listen for one to sound different from the others. Happy Hunting

Sloppy ride, fairly noticeable jolt when applying the brakes abruptly, visual crack and movement.
