1996 Lincoln Town Car suspension problems

1996 lincoln town car steering went out causing consumer to run into a fence. The steering wheel would turn left and right but the wheel did not respond. Rear air spring were replaced due to excessive cracking. The vehicle steering a suspension performed poorly. The dealer replaced the upper and lower ball joints and the inner and outer tie rods. The right front window regulator broke. The interior light on the left side of the vehicle did not work.

While driving my 1996 signature series town car about 25 mis/hr in residential area the right front ball joint suspension collapsed & "rolled" under the car frame. The slow speed enabled the car to be stopped within feet. Driver & a passenger unhurt. Car towed to aaa certified garage that had been used for over 25 years. Suspension replaced as was the left one that mechanic deemed ready to also collapse. Resident municipality literally surrounded by expressways whose speed limit is 65 mis/hr.
