You have posted 2 threads in this 79-95 forum, but your avatar shows a 2010 and above as I really can not tell by how black it is.
If it is a whining noise from the rear or trans area, It may be a TOB if in the trans area, or a pinion bearing in the rear. But by your description, it sounds as if it is coming from the tranny area.
The squeeking noise may be a spring unloading when taking off when it squats.
