I am pretty sure it is the belt not the pump. Stock Bronco pump with PS and hydroboost. It has been squealing for a while but is slowly getting more annoying and constant. Everything works great and the fluid is topped off with PS fluid.
At idle it is usually ok if you have your foot on the brake. If you are cruising along at low speed it squeals constantly. If you move the wheel back and forth it does not change the sound. If you are in park foot off the brake it will squeal but stop as soon as you put your foot on the brake. I tried silicone spray and tighten the belt up but no change.
New or different belt? Sand the pulleys? Different spray product? I know serpentine but I am not ready to stop driving this for a yet!
