Presuming u loosened the adjusting idler pulley to remove the old belt, it sounds like the new belt needs to adjusted a pinch tighter.

In fact, I have had to do this every time I changed the belt on my 99.....Even good quality belts "stretch" just a very tiny bit when under load.
The belt on the 4.0 needs to be awfully darn tight to stay quiet. Tighter than most any other vehicle I've owned. Snug it a bit and I'll bet that noise is gone.

Try 1/2 turn on the adjusting bolt at a time. Be sure to loosen the idler pulley 1st, then turn the adjusting bolt 2nd, then re-snug the idler pulley 3rd. Still squeaks, try another 1/2 turn adjustment.
