Question: is all the Ford dealer doing is installing coil spring guards and not replacing the springs? This is about their speed (backwards), like the cooling fan fuse install. They do not replace the (maybe) defective fan motor and stick a fuse in that will blow when it craters. Then they sell you a new cooling fan assembly for $400 - what a rip. The coil spring breaks, the guard keeps the spring from carving up a tire so avoiding an accident, sell (former) customer new springs, blame state work crews for using salt to melt snow and ice instead of the spring supplier.
I heard years ago that Ford lost track for a few years (cost cutting) of what parts went to what plant into which models on what day.. Quality control got laid off. mad
