Hello, I have a 94 Caravan that I have had for over 10 years. The alignment has always been slightly out but not enough to worry about. Probably over a year ago I started experiencing more problems with it. One of these problems is that my front passenger tire keeps getting ate up on the inner side of it. The other is sort of a slight jerk and click noise right as you first start to accelerate. I had replaced the front struts and wheel bearing on that side last year yet the tire gets ate up still. A few weeks ago I noticed that the boot on one of the inner tie rods was damaged so I went ahead and replaced both the inner and outer tie rods. While doing this I had also noticed that the wheels when turned all the way to either side is rubbing away at the plastic and metal depending on which way it is turned. They are the proper size of tires so I am also wondering why the turn goes too far. The outer tie rods took between 25 to 27 turns taking them off so I installed both new ones at 25 turns. I am curious if that is too many and possibly causing too much turn radius. Another thing that I noticed was on the driver side boot of the inner tie rod there is a small hole that goes onto a piece of metal and this piece of metal moves back and forth a little and I don't think it should. I have attached pics and a video link. If someone could help it would be much appreciated.
1. What is this clicking noise and should there be play in the wheel like this?
2. What is the small metal piece that the small hole in the boot covers, what is it's purpose and am I correct in thinking it should not move?
3. Why do these wheels go so far when steering all the way that it is rubbing in the wheel well, could it be that 25 turns on tie rod like it was originally is too much or would it be something else?
4. Any other ideas on what could be wrong to cause the inner side of that tire to lose it's tread?
