Made me grease my 2 u-joints,and took my fuel gauge sender out to look inside the tank,was pretty cleanin there. This51 6400 pickup burns only propane, so I haul lawnmower gas in the cab tank and siphon it out when we mow. 98 inch wheelbase with 8.25 rubber on original 3 piece wheels is the best pick-up Iv'e had. built My own heavy duty 4-link using 7/8 heim joints,run it most days .
