The idler pulley on any vehicle is used to maintain the proper tension on the vehicle's belt(s). without it belt maintenance would be difficult.
A deflection pulley is used to change the direction of a belt or chain, while an idler pulley is used to maintain tension in the belt or chain. In other words, deflection pulleys guide the belt around corners or obstacles, while idler pulleys help keep the belt taut and prevent slipping.
Take the belt off, take the bolt off of the idler pulley, take the pulley off, put a new one on replace the bolt, and put the belt back on
The last model year for the full size Ford Bronco was 1996 . The Ford Bronco NEVER used the 4.6 liter V8 engine
There is a small bearing in there and sometimes they just fail. The bearing can't really be changed so you'll have to buy a new or used idler pulley.
Idler pulleys are used to maximize belt contact with other pulleys and to redirect belt around other parts that might interfere with the belt.

Yes, idler pulleys can change the direction of rotation in a belt-driven system. They are used to guide and tension the belt, allowing it to reroute around obstacles or to achieve the desired alignment of components. While the idler pulley itself does not directly drive any load, its placement can effectively alter the path of the belt and the direction of the rotational motion transmitted through the system.
It may be the Idler pulley. I used to have a 96 Breeze with a 2.0L 4cyl that made a whining noise. I thought something might be seriously wrong, but then i discovered it was just the Idler pulley making noise. I changed it-- no more noise.
