Strange noise from front… ?
Correct I have airmatics but if the noise is very little then you may also have a leak on the airmatics but if the shock is gone then it is a very loud thud or your car will just sit on the ground.
The noise is only discernable on a) smooth roads (like car parks) and b) between 15 and 20mph!
Any faster then road noise could mask it I think. Any roughness on the road an road noise masks it.
Any clues chaps?

A bad wheel bearing can damage the spindle assembly and possibly leave the vehicle. You might want to look closely at this one.
But I just had another chance to make sure that there is no free lunch!
I got ~20K miles out of it. Those could probably go for another 5, but on one of them (RR) the metal court came out. ))But I don’t think those were the reason for that noise.
There is only one thing could think of - I probably tolled you this sad story before, but… I took this car to the MB dealer for the alignment right after I had those tires replaced. The first time they were not able to make the steering wheel straight and car was pulling to the right, so I brought it back. Another guy performed the alignment for the second time, but told me that the car pulls a side because of the tires that grubbing the roat to much (or some BS like this, idiot)… to make long story short, I took my car to my friend’s garage, he has a lift, and right away figured out that front wheel bearings had too much play. I adjusted it and the pull has gone, the car became perfectly normal.
I think maybe they had something not tighten up enough when did the alignment, so it become even more loose and that noise came up? I am not sure what are the alignment point’s there, but I don’t have another theory at this time.
Day 1- Replaced lower ball joints- speed bump squeaking and farting is gone, but still have the rattle.
Day 2- Replaced stabilizer bar with the bracket (Came together) and the links. - Same noise.
Day 3- Replaced lower control arm- same noise
Day 4- Replaced shock with upper control arm with attached ball joints....- Same noise $W$T$F$

........
So I changed both tie rods and did an alignment today. -- All noise gone...i probably didnt even have to change the tie rods..
I dont know if i have to be happy or angry...
Now parts for sale: perfectly fine driver side used air shock, used upper control arm.

DJ, Please update us after about 1000 miles or less to see if the sound returns.
After you changed all of that, my guess is that it would have to be something with the steering rack (inner tie rods?). I'm no mechanic but i tried to carefully listen to the exact location and i cant really define where but thats my best guess. I'll carefully remove the boot this weekend to inspect.
I will definitely let you all know how long mine lasts.
I think it was 95% the tie rod since the ball joint that was attached to it was very loose compare to the new ones. I’m not sure if it’s inner or outer, but it’s the one that looks like "C" and it attaches to the knuckle by ball joint.
I just hope mine lasts more than 1000miles!!!

What are some solid indications of worn bushing? Sound when breaking and turning, a feeling in the steering wheel or floor? etc...

Iblaho,
A bad bushing might leak fluid so it can make it easier to see exactly which one is bad. Otherwise you can try to move it around to duplicate the noise. Usually a bad bushing would be heard as a thump on a change of acceleration/braking/going over a decent bump. Most common to fail is the thrust arm bushing. Our problem was noticeable on small bumps and all of our bushings were good. The sound also was more of a rattle.

Yesterday I checked it again, just off ramps, and found the following:
1. The “link’s ball joint on the leftt hand side is pretty much gone – that would kind of id explain the noise that I am getting since the link is connected to the sway bar. I could not see it when the car was hanged on the lift, but it is discoverable when landed on wheels and by now it is in much worth shape.
2. On the right side, the link ball joint seems to be ok, but there is a play – I did not have anybody to help me shaking the wheel (at this time I had the car on the jack), but I have a feeling I will have to replace # 13 (big one) bushings on both sides.
Basically, the next step is to replace # 12 with all the “robbers” in it.
I will keep you posted!
