I have a 2013 R/T Classic 6sp manual and I noticed some loud growling noise coming from under he hood. (Not the good rumbly Hemi noise, but more like bad bearing noise.) I checked all around and found the input shaft on the water pump had a lot of play. I tok the car in and they finally agreed with my diagnosis after first replacing an idler pulley, that indeed he water pump was bad. Here's the rest of the story, my car only has 9000 miles, and the part is on national back order and I was told it can be days to weeks until it comes in. Has there been a lot of premature failures on these water pumps? Maybe I suck at google searching, but I really didn't see many threads.
