1990 century front end problems

I have a '90 century, 3.3L, with 168,000mi. It was in an accident, and there was some side to side play in the passenger front wheel only. Now a while after the accident it has gotten much worse and it is much looser. The outer tie rod ends are fine, and it is only on the passenger side, could the problem have to deal with the ball joint for the tie rod?

thank you

It could very easily be the ball joint but it could also be bad bushings in the a arm. Pull the tire off an see if you can see where it is moving. This will give you a good idea what repairs you will need.
