My stock 81 did wear the tires but after I lifted it a couple inches and put airlift airbags in the front coils that issue was solved. I had 3 IFS Broncos and wore out 2 sets of ball joints and 1 u-joint in about 250k miles. Unless I was going to run tires over 35" I would just keep the IFS.
x2, and If did do a SAS, I would only do a D60, not a 78-79 D44.
