97 Intrepid with steering issues

I have a 97 Intrepid with about 114,000 miles on it. Just about two weeks ago I had the outer and inner tie rod bushings on both the right and left tie rods replaced, and I also had the right outer tie rod end replaced (about a year ago I had the left outer tie rod end replaced). In addition to that I had the left wheel bearing hub and assembly replaced. Before the repair I noticed my steering wheel would shake a little while driving down the road, and when cornering left at a fairly normal speed I would sometimes feel the left wheel vibrating as if trying to turn, and then it would give a huge jerk and I would turn normally after that. Well I haven't noticed the wheel shaking after the repair, and I even cornered hard to the left to make sure the car didn't jerk, and it never did. But just tonight, it did it twice while I was driving around and my wheel started shaking a tiny bit again (not as bad as before). I'm planning on taking it back in to the same place, I think something must have broken right away, but just for comparison, what does it sound like to you?
