Whats wrong with my Dusters front end?

Get "one of you" under the car so someone can turn the wheel in various ways back and forth, looking for movement that should NOT be there as well as movement that is NOT there that should be

What are you using for tires?

What did you use for alignment specs?

Start with the steering coupler. Gently wiggle the wheel back and forth, looking for UNWANTED relative movement between the steering column shaft and the coupler, as well as between coupler and box shaft

Look for LACK of movement at pitman arm as wheel is wiggled.

Go on down the system step by step from there

Don't assume anything. Broken / cracked K member or A arms, etc

Tires and alignment make a TREMENDOUS difference.
