Chrysler Repair: 99 Chrysler 300m grinding/rubbing/squeaking from front end., chrysler 300m, brakes squeak

Question
My Chrysler is making a roaring/grinding noise when coming to a stop.  I have changed the axles, one of the boots, the transmission support (it was broken) and the brakes and rotors.  It is also making a rubbing/squeaking noise when I make sharp turns, as though something in the suspension is shifting, and this seems to affect the frequency and loudness of the grinding/roaring.  The brakes squeak like no other when this happens.  It only does this after the car has been driven for a bit (warmed up) but does not when its cold.  It does however make the shifting noise when cold, and does this only when making sharp turns or when taking off from a stop too fast.  Any idea what it could be.  I am starting to lose hope :( .

Answer
Well obviously you have some movement in you suspension.An easy way to look at this is to do a dry park.With the car off and on flat ground have someone shake the steering wheel back and forth while you lay underneath feeling for looseness.

There is something else you should check.They are called cradle bushings.The engine cradle is a large u shaped piece that cradles the engine.There are 4 large bolts at the corners.There is a bushing at the bottom and 1 between the cradle and the frame.Also there is a bar that goes across the back that holds the trans mount.You want to make sure those bolts are tight too.
