Steering wiggles

I'll up the ante on the steering box bolts. Definitely check to make sure the bolts are tight, but you'll want to check to make sure the steering box mount itself isn't moving on the K member. The steering box mount on my Duster was actually cracked in the middle from the welds being broken on the front brace. When the steering wheel was turned, the entire steering box was rocking back and forth, separating part of the steering box mount from the k frame. Based on what I've seen of the welds on some of the K members on these cars I'd guess it happens occasionally.

Check to make sure the bolts are tight, then have someone else turn the wheel back and forth while you look at the steering box. If the steering box moves at all, you'll have to look at the welds on the K frame. I've been seam welding and reinforcing my K-frames. Helps with handling, but part of the process is reinforcing the steering box mount and going over the factory welds as well.
