Hello everyone. I know this is a 2011 forum but I'm curious about the ram 1500's 2010 and up. I know people have posted about the sloshing of the fuel when coming to a stop, it almost feels like a slight bump from behind. My question here is has anyone felt a slight thump or clunk during accelerations? My truck from day one has clunked on I'd say 2 out of every five starts from stop when I have over a 1/2 tank of gas. It feels like a clunk in the drive train resembling a bad u joint. Once I get below a half tank the clunk goes away. I have the 32 gal tank. Brought it to dealer with 3/4 of a tank and they heard the thump but couldn't find the issue.
