amc49 If dogbone then you will catch the clunk on and off power going straight ahead too.

Turning only at full lock says strut mount or balljoint. Sometimes you swear the joint is tight but you cannot replicate the exact forces on a ton and a half car with a crowbar. BTDT.

Not CV, if clunking there is no way you won't catch it going straight or close to straight too. The wear in CVs is mostly in the straight ahead position, once you vary from that even a little you would run into the clunk long before you get to full lock steering. In CV the clunk is the ball snapping from a worn slot to the relatively unused new part of slot towards the ends. There is an edge that develops there from two arguing slot patterns, the ball snaps across it. The edge should generally show around a half turn or so, not full lock only.

smurf91 My 00 se is doing the same. I replaced control arms,end links,tierods only to find it was the strut mount! My car has 109,000 on it. The rubber around the mount is cracked and showing age.

My culprit turned out to be a busted upper strut mount. I did some research and found that the upper strut mount is common to blow on these things.

To me yours sounds like either a control arm ball joint, and upper strut Mount. Try the upper strut mount first.
This sounds like a very plausible cause as well.

I've replaced the driver and passenger side motor mounts but I didn't do the dogbone. Its probably about time. car has 105,000 miles.
Yes. The "dog bone" or torque strut mount has bushings that can wear out and cause that.

SilverST05 This is sounding like bad motor/transmission mounts.

ligardner Hey you-all thanks for the suggestions. But maybe its not really the CV joint. My gut feeling is that it is something else. This loud noise can happen at real low speed if the wheel is jacked hard enough. And then it Un-clunks if you put in reverse and then slam on the brakes keeping wheel jacked hard. Whatever is slipping and clunking is moving back and forth when the steering is stretched out in a certain way.

Now it is true that the CV joint will be stressed in this exercise, but this clunk is substantial--you can feel it with your foot. I don't think the CV joint can clunk like that.

How can I assess the stabilizer bar bushing and clamp? I suppose I could take the bar off the car and drive the car without it on my street just to see if the clunk is gone. Might be the only way, yes? If the bushing and bar are clunking arround inside the bracket there's no way I could see evidence of movement with bar in the bracket and on the car.

How does this sound as a strategy?

SilverST05 Most probably the CV joints.

2003 Ford Focus One tell-tale sign that it may be a CV is a boot that is split, or wet with grease. If you grab the CV there may be some play in it up, down or side to side.
