Vehicle experiences a violent shaking in the steering and front suspension called "the death wobble". Occurs as speeds between 40 and 70 mph. Occurs if road is somewhat bumpy. Occurs often and could result in loss of control. It requires that I slow down to about 5 mph before it stops. This immediate need to slow down if dangerous if someone is following me (especially a large truck. ).
Report receipt date: Jul 15, 1998 NHTSA campaign number: 98v161000 component(s): fuel system, gasoline , suspension my rear suspension is bad - has this been taken care of on my vehicle? gem module is having trouble. I have been reading this part has caused a lot of trouble for this Ford model.
Shock upper mount simply fell off causing driver side rear shock to drag ground. After further inspection also noticed at the location of the rusted out mount location that the rear wiring for the tail light were severed causing truck to now be stuck in park. Also while inspecting noticed rear frame is simply falling apart and other areas throughout the frame are weak as well. This is a huge safety concern after doing research I am finding many accounts of the same issue online but no manufacture recalls. Why isn't Ford doing anything about this issue? I've never seen frames do this. Truck needs full frame replacement.
