I have an 03 Dodge 2500 w/ hemi 4x4. Are they known for transmission or rearend problems? Whan I slow down it makes a noise like a playing card in a bike spoke. One time it sounds like its in the rearend but then the next its elsewhere. Anyone have any ideas what it could be before i spend mega bucks on labor w/ a mechanic. You only hear it when you are slowing down or holding a steady speed like 25- 35mph. It has 66,000 miles on it and ive never pulled w/ it but the previous owner did cause there is a trailer brake under the dash. Any help is very much appreciated.
