How to fix that? It gives a scraping sound when passing different leanings like when turning into my drive way. Right now it is four shiny scraped rings almost all the way back on the drive shaft just before the rear axle gearbox.

Let me guess,you've lowered the truck,if so spring for an adjustable track bar,and shift the rear end over so the driveshaft doesn't rub on the tank
