This truck had 91,074 miles which was mostly highway without a trailer. The complete clutch components failed striped down to the rivets. Had the G56 components replaced with a South Bend Clutch. Everything felt good as I drove it back home. Two days later when I got in it the batteries were drained dry. Put the battery charger on, placed the key in the ignition, and numerous warning and interior lights started flashing non-stop.
