to check what you have, Set the chassis on stands as level as you can and remove one of the front hubs so you can see both top and bottom ball joints. get a builders level in upright position aligning with bottom joint. The top joint should be trailing the bottom joint. the trail should be about 10-12 degrees. If its not trailing then there is the problem. you will need to adjust this trail by either washers on the inner bush connections or the body mounts. In some cases the top wishbone might have been fitted wrong way round.
If you have too much turning angle on the rack this can counter the caster effect on full lock. Restricting the turning angle will help.
