Ok So I pretty much baby my truck. After getting home I put my truck in reverse to back into the driveway and, clunk? I put it in park and said maybe it was something else. I put it back in reverse and another clunking noise... I put it into neutral and then drive and it also clunks in drive. Im not really familiar with RWD vehicles so I couldnt tell you what anything is under there besides the exhaust, differential, and driveshaft lol. What could be causing this clunk? Think the dealership will repair it under the warranty?
