According to your description,you say it only whines under load,and more
noticable at high speeds.In my experience with this it has turned out to be
the pinion bearings.( twice in a 92)Did this place replace these bearings?
If so, did they replace the crush collar and adjust the preload to factory
spec? Be sure you have the old " Chrysler Clunk"or the pinion is
overtorqued.I burned out a pair of bearings in 2 days due to a misprint in
my FSM. Hope this helps Steve
