F53 death wobble?

It is rather funny that in all my years of repairing and rebuilding front ends I do not recall anyone coming in in a relatively newer unit complaining about the vaunted death wobble that Ford has. It would seem that I should remember someone having done so. I do recall people complaining about it in GM vehicles like Cad's, Buick's, Oldsmobile's, Pontiac's and Chevy's but then that wasn't because of long leaf springs, maybe it was caused by too big of coil springs. As I said before, if you have the problem something is worn and needs to be replaced. Too many Ford chassis owners do not have the problem for it to be caused by the long leaf springs. Again I add installing aftermarket items simply masks the problem, someday you will find out when the tie rod end or something else breaks and your steering becomes dangerously erratic. As to increased caster being the cause, whomever planted that seed should go to alignment school.
