Default Loud Suspension Noise

On my 98 Bonneville SLE, when I drive it around 25 mph, it makes a fairly loud sound, almost once every revolution of the wheel. Then around 30, it gets really really loud. It'* a loud clunking, and looking under the car, the link for the anti-roll bar looks a little messed up, but I can't move it. Any ideas? Thanks.

Pics of the endlinks and balljoints on both sides, please.

In the meantime, jack the car up in front to get the weight off the wheels and start shaking things.

When shaking,

Put your hands at 12 and 6 on the tires.. wiggle
Also 3 and 9 wiggle.

If either of those feel loose or have play, get a helper to watch while you move the wheel to determine what part is bad.

Shaking parts under the car will help isolate the problem also. Swaybar, A-arms, etc.

While you're checking things, check the strut mount bearings, also. Does it have sort of a spring type "sprong" sound when it does it? Have someone turn the wheel while you watch. Does the top part of the strut move smoothly, or does it catch and when it lets go, you hear the noise?

Is there any shake or shimmy while driving? Can you feel it up through the steering column?
Is it worse on hard acceleration?
Is it louder or more apparent when you are making a turn?
Does it get worse when you hit a bump?
Does your call pull to one side or another?

Turned out to be one of the anti-sway bar bolts had broken.

Sure sounded like the lower frame was coming off.

I like cheap fixes!

Thx for all of your help and responses.
