Whenever i WOT the truck, it downshifts and almost sounds like the belt is squealing right when the RPMs shoot down.. Always thought the truck was just breaking traction, but it doesnt sound "good". Not really a huge concern, just would like to know what it might be...

 

slipping belt?

worn out tensioner, wrong # of ribs pulley on say a recently changed alternator?

 

Put a Gatorback serp belt on it.

 

hard to install yourself?

 

naw man..belts are EASY to take off and put on..just follow the diagram under the hood..

 

just rent yourself the serp belt tool for the tensioner or your hands with be destroyed by the fan if you use a ratchet
