Death wabble

I have read multiple postings on here about the
Death wabble, I too Have 2017 f350 King ranch an
my issue seem to have started about 25000 miles.
Same wabble on the highway at about 70 speeds
and the whole front end goes crazy like it's tearing
apart. Happened 3 times so far with plenty of
weight in the back. The dealer never mentioned
the Death wabble. They replaced the ball joint and
did the alignment at my expenses. Fixing to go
back tomorrow now that I know some of the
history with other owners. Thanks
