Front Suspension Stabilizer Bar problems of the 1999 Lincoln Navigator

Heard clicking noise when turning corners. Took 1999 Lincoln Navigator in for inspections and found that the following parts needed replacing: ball joints (front-left), remove and replace control arm, lower, one side, sway bar link-remove and replace stabilizer bar control, alignment cams/wedges (front-left including alignment adjustment. Very costly and time consuming repairs. Since I travel a lot I feel more than blessed that there was not a break down in route of a trip. Was told that this indeed could be very dangerous if not repaired immediately.
