Just started today. There is a loud almost Clicking/Clacking noise that comes from underneath my truck. More towards the rear and it gets faster as I go faster. When I slow down around 10-15 mph its gets slower and will pause and start again randomly until I come to a complete stop in which case the noise stops. It does it in reverse forward and if I'm rolling and put it in neutral. I looked under the truck and didn't notice anything rubbing anything or coming into contact with anything. I recently had new tires put on but they've been on for about a week now. Any help would be much appreciated. I had 4.56 gears installed but that was about 40,000 miles ago. I have 58,000 on the truck now. Theres is no leaking from the rear diff as well. Also its a 2wd Hemi if that helps.

id get under there and check it out and find out where the noise is coming from.

kinda sounds like a u-joint on the rear end

thats what i think u joint

trust me its no u joint . its the rear diff. or the damm rear drum brakes
