Sounds like you have a good start on getting everything firmed up...
R&R of the Tie Tods, Center Link, & Idler arm is a very good start... ALL of the suspension components work together as a whole to affect the feel of your car..
Your Ball Joints COULD have some slop.
Also Very Likely is the Possibility of your Upper and Lower Control Arm Bushings being worn.
You could take care of all of these items by replacing the Bushings & Ball Joints at the same time. If you are going halfway with the dissasembly doing one why not do both..and save yourself the hassle later.. [img]graemlins/
After all the above has been addressed, then that would only leave your Steering Gearbox..there are different schools of thought on this, but depending on your mileage, driving habits & tire size the gearbox will take a bit of wear and translate that back to you..
I replaced all the above Steering Components, Ball Joints & Bushings then replaced my Steering Gearbox with 125k miles on it.. Drastic Improvement and I KNOW I dont have to worrry about any of it for a while.... Just a thought.
