I think i got it .. i went to go look around at the crankshaft pulley to see what the sheave could possibly be.. i tugged on the fan which had no concerning wobble. I spun the fan by hand and could here the squeal .. i started the truck snd squeal was there i sprayed the water pump pulley with water and it immediately went away comes back once water drys up i spray again and it goes away. The belt seems to be slipping on pulley .. the fan pulley even just spins by hand way to easy slipping off belt. I have belt really tight so it has to be the width size of belt.. waiting on 5/8 belt had to order it no auto store carried a 5/8 x 44 i tried a 43 but could not get it around pulley .. belt teeth kept it from going on so i have go a little bigger on belt size..
