Personal link deleted I have a 1990 Buick LeSabre that has a steering geometry problem
When I go into a curve the car will lurch and the steering wheel will attain a position that is a few degrees off of what was the straight ahead position. This position will remain until I enter an opposite curve or if I hit a rough spot on the road. This is very consistent. If I were not aware of this change in geometry, the lurch might literally throw me into another lane. I have checked or replaced the hub bearings. I replaced one inner tie rod end. I replaced the struts. I also noted that the camber angle changes between the two settings when I checked it with a spirit level. Also when I enter a curved-to-the-right exit ramp, I sometime get a slight squealing of the front tire. As long as I am on a straight level road, I have no problem and the steering wheel is positioned as it should be. I tried to check for movement of the steering rack, but I was unable to see any movement or signs of movement.
Some immediate thoughts about the symptoms are:
How can I check the lower ball joints?
How can I check the top strut supports under the plastic caps in the inner fender where the strut nut is located?

I think your barking up the wrong tree here. Your Camber isn't really changing. It's normal for it to lean on turns. Check the mount bushings for the Rack and pinion and see if the rack is sliding side to side.
