1993 Chrysler Concorde steering problems

Purchased car used, the front caliper had to be replaced . Tie rod bolt to front left wheel fell out, steering inoperable. Brakes began vibrating at 23000 miles, when braking brakes sounded like metal on metal, brake shoe on the front left was completely gone and rusted. Water pump failed and was replaced. *slc

1. No gradual signs. One day, front end very unstable, shaking and wobbling - as if front end not aligned or bad tires / inflation. Steering the vehicle was a challenge & felt very unsafe. Same day, I took vehicle to tire store to have looked at, tires checked / rotated if needed. Replaced one rear tire that was soon to be needed and checked inflation on others, etc. 5:30pm, I was sent on my way. Car drove better it seemed - for approx. 4 miles. 2.
