One problem related to suspension noise has been reported for the 1998 Lincoln Mark Viii. The most recently reported issues are listed below.
Update to last complaint: the passenger side hid headlight has failed, no replacement except $1000 conversion kit. Have to drive with only "brights" on from now on. Danger to myself and those I'm passing, plus if the "brights" aren't on, then I have no headlights and could get pulled over. Passenger side ball joint/control arm broke while driving and tire fell off while driving in parking lot at work. After repair, hearing a bad creaking noise. Air suspension has to fill up all the way when I start the vehicle even after 5 minutes of it being shut off. Have paid $1,200 for repairs of suspension and steering in 6 months. (that's with my dealership employee discount). Seriously, I've heard too much about defective ball joints, headlights, no heat, door handles snapping off, and the air suspension going bad. Why is Ford not doing anything about these obviously defective parts??? because the car is rare and they don't make them anymore???.
